Autonomous Drone Navigation via Learning from YouTube Videos - Available
Description: Be it mastering a new recipe, performing complex mechanical repairs, or excelling at video games, humans have the ability to learn new skills by just watching an expert perform the task. They often do so by simply watching online video demonstrations, despite significant variations in body shapes, environments, or sensing modalities and, most importantly, without knowing the precise action commands of the expert demonstrator. Inspired by how humans learn, this project aims to explore the possibility of learning flight patterns, obstacle avoidance, and navigation strategies by simply watching drone flight videos available on YouTube. State-of-the-art Large Vision Models for processing and encoding videos, as well as unsupervised training techniques, will be evaluated and designed during the project. Applicants should have a strong background in machine learning, computer vision, and proficiency in Python programming. Familiarity with deep learning frameworks such as PyTorch is desirable.
Goal: Investigate the feasibility and effectiveness of using large vision models along with self-supervised learning techniques to teach drones to navigate autonomously from YouTube videos. Develop a prototype system capable of learning from online videos and demonstrate its effectiveness on a real drone platform.

Hybrid Spiking-Deep Neural Network System for Efficient Event-Based Vision Processing - Available
Description: Event cameras are innovative sensors that capture changes in a scene dynamically, unlike standard cameras that capture images at fixed intervals. They detect pixel-level brightness changes, providing high temporal resolution and low latency. This results in efficient data processing and reduced power consumption, typically just 1 mW. Spiking Neural Networks (SNNs) process information as discrete events or spikes, mimicking the brain's neural activity. They differ from standard Neural Networks (NNs) that process information continuously. SNNs are highly efficient in power consumption and well-suited for event-driven data from event cameras. In collaboration with SynSense, this project aims to integrate the rapid processing capabilities of SNNs with the advanced analytic powers of deep neural networks. By distilling higher-level features from raw event data, we aim to significantly reduce the volume of events needing further processing by traditional NNs, improving data quality and transmission efficiency. System will be tested on computer vision tasks like object detection and tracking, gesture recognition, and high-speed motion estimation.
Goal: The primary goal is to develop a hybrid system that combines Spiking Neural Networks (SNNs) and deep neural networks to process event data efficiently at the sensor level. We will demonstrate its versatility and effectiveness in various computer vision tasks. Rigorous testing in simulation will assess the impact on data quality and processing efficiency, followed by deployment on real hardware to evaluate real-world performance.

Description: In recent robotic advancements, motor policies trained in simulations have achieved impressive real-world performance. This project aims to leverage the high-temporal resolution of event cameras to improve the robustness of these motor policies by incorporating event data as an additional sensor input. Current simulation methods for generating event data are inefficient, as they rely on rendering many high-frame-rate images. This project focuses on creating a shared embedding space between events and frames, allowing motor policies to be trained on simulated frames and deployed using real-world event data. Depending on the project’s progress, the proposed methods can be tested on various robotic platforms, including quadrotors and miniature cars.

Enhancing Neural Scene Reconstruction through Multimodal Fusion - Available
Description: Recent advancements in neural radiance field and 3D Gaussian splatting have shown remarkable success by fusing together vision and semantic modalities for improved reconstruction quality. In this project, we build upon this recent trend and investigate how the use of modalities such as depth, semantic classes, normals and event data, coming from different sensors, can improve 3D reconstruction. The project aims to explore how prior 3D information can assist in reconstructing fine details and how the help of high-temporal resolution data can enhance modeling in the case of scene and camera motion. By exploring the fusion of these modalities, we aim to achieve more accurate and detailed representations of complex environments.
Goal: The primary goal of this project is to evaluate the fusion of multiple sensor modalities, including RGB, depth, and event cameras, for enhanced scene reconstruction quality. We aim to leverage the unique strengths of each modality to achieve finer detail reconstruction and effectively handle complex scenes.

Advancing Space Navigation and Landing with Event-Based Camera in collaboration with the European Space Agency - Available
Description: Event-based cameras offer significant benefits in difficult robotic scenarios characterized by high-dynamic range and rapid motion. These are precisely the challenges faced by spacecraft during landings on celestial bodies like Mars or the Moon, where sudden light changes, fast dynamics relative to the surface, and the need for quick reaction times can overwhelm vision-based navigation systems relying on standard cameras. In this work, we aim to design novel spacecraft navigation methods for the descent and landing phases, exploiting the power efficiency and sparsity of event cameras. Particular effort will be dedicated to developing a lightweight frontend, utilizing asynchronous convolutional and graph neural networks to effectively harness the sparsity of event data, ensuring efficient and reliable processing during these critical phases. The project is in collaboration with European Space Agency at the European Space Research and Technology Centre (ESTEC) in Noordwijk (NL).

Fine-tuning Policies in the Real World with Reinforcement Learning - Available
Description: Training sub-optimal policies is relatively straightforward and provides a solid foundation for reinforcement learning (RL) agents. However, these policies cannot improve online in the real world, such as when racing drones with RL. Current methods fall short in enabling drones to adapt and optimize their performance during deployment. Imagine a drone equipped with an initial sub-optimal policy that can navigate a race course but not with maximum efficiency. As the drone races, it learns to optimize its maneuvers in real-time, becoming faster and more agile with each lap.
Goal: This project aims to explore online fine-tuning in the real world of sub-optimal policies using RL, allowing racing drones to improve continuously through real-world interactions.

Inverse Reinforcement Learning from Expert Pilots - Available
Description: Drone racing demands split-second decisions and precise maneuvers. However, training drones for such races relies heavily on crafted reward functions. These methods require significant human effort in design choices and limit the flexibility of learned behaviors. Inverse Reinforcement Learning (IRL) offers a promising alternative. IRL allows an AI agent to learn a reward function by observing expert demonstrations. Imagine an AI agent analyzing recordings of champion drone pilots navigating challenging race courses. Through IRL, the agent can infer the implicit factors that contribute to success in drone racing, such as speed and agility.
Goal: We want to explore the application of Inverse Reinforcement Learning (IRL) for training RL agents performing drone races or FPV freestyle to develop methods that extract valuable knowledge from the actions and implicit understanding of expert pilots. This knowledge will then be translated into a robust reward function suitable for autonomous drone flights.

Language-guided Drone Control - Available
Description: Imagine controlling a drone with simple, natural language instructions like "fly through the gap" or "follow that red car” – this is the vision behind language-guided drone control. However, translating natural language instructions into precise drone maneuvers presents a unique challenge. Drones operate in a dynamic environment, requiring real-time interpretation of user intent and the ability to adapt to unforeseen obstacles.
Goal: This project focuses on developing a novel system for language-guided drone control using recent advances in Vision Language Models (VLMs). Our goal is to bridge the gap between human language and drone actions. We aim to create a system that can understand natural language instructions, translate them into safe and efficient flight instructions, and control the drone accordingly, making it accessible to a wider range of users and enabling more intuitive human-drone interaction.

From Floorplan to Flight - Available
Description: Drone racing is considered a proxy task for many real-world applications, including search and rescue missions. In such an application, doorframes, corridors, and other features of the environment could be used to as “gates” the drone needs to pass through. Relevant information on the layout could be extracted from a floor plan of the environment in which the drone is tasked to operate autonomously. To be able to train such navigation policies, the first step is to simulate the environment.
Goal: This project aims to develop a simulation of environments that procedurally generate corridors and doors based on an input floor plan. We will compare model-based approaches (placing objects according to some heuristic/rules) with learning-based approaches, which directly generate the model based on the floorplan. Requirements: - Machine learning experience (PyTorch) - Excellent programming skills in C++ and Python - 3D Modeling experience (CAD, Blender) is a plus

Description: Recent progress in drone racing enables end-to-end vision-based drone racing, directly from images to control commands _without explicit state estimation_. In this project, we address the challenge of unforeseen obstacles and changes to the racing environment. The goal is to develop a control policy that can race through a predefined track but is robust to minor track layout changes and gate placement changes. Additionally, the policy should avoid obstacles that are placed on the racetrack, mimicking real-world applications where unforeseen obstacles can be present at any time.

Event-based Particle Image Velocimetry - Available
Description: When drones are operated in industrial environments, they are often flown in close proximity to large structures, such as bridges, buildings or ballast tanks. In those applications, the interactions of the induced flow produced by the drone’s propellers with the surrounding structures are significant and pose challenges to the stability and control of the vehicle. A common methodology to measure the airflow is particle image velocimetry (PIV). Here, smoke and small particles suspended in the surrounding air are tracked to estimate the flow field. In this project, we aim to leverage the high temporal resolution of event cameras to perform smoke-PIV, overcoming the main limitation of frame-based cameras in PIV setups. Applicants should have a strong background in machine learning and programming with Python/C++. Experience in fluid mechanics is beneficial but not a hard requirement.
Goal: The goal of the project is to develop and successfully demonstrate a PIV method in the real world.

Foundation models for vision-based reinforcement learning - Available
Description: Vision-based reinforcement learning (RL) is more sample inefficient and more complex to train compared to state-based RL because the policy is learned directly from raw image pixels rather than from the robot state. In comparison to state-based RL, vision-based policies need to learn some form of visual perception or image understanding from scratch, which makes them way more complex to learn and to generalise. Foundation models trained on vast datasets have shown promising potential in outputting feature representations that are useful for a large variety of downstream tasks. In this project, we investigate the capabilities of such models to provide robust feature representations for learning control policies. We plan to study how different feature representations affect the exploration behavior of RL policies, the resulting sample complexity and the generalisation and robustness to out-of-distribution samples. This will include training different RL policies on various robotics tasks using various intermediate feature representations.
Goal: Study the effect of feature representations from different foundation models on learning robotic control tasks with deep RL and imitation learning.

Sim-to-real transfer of event-camera-based RL policies - Available
Description: This project aims to develop and evaluate drone navigation policies using event-camera inputs, focusing on the challenges of transferring these policies from simulated environments to the real world. Event cameras, known for their high temporal resolution and dynamic range, offer unique advantages over traditional frame-based cameras, particularly in high-speed and low-light conditions. However, the sim-to-real gap—differences between simulated environments and the real world—poses significant challenges for the direct application of learned policies. In this project we will look try to understand the sim-to-real gap for event cameras and how this gap influences downstream control tasks, such as flying in the dark, dynamic obstacle avoidance and, object catching. This would include learning representations for event data ( ideally while reducing the sim-real domain gap) and training navigation policies using either reinforcement or imitation learning methods.
Goal: Train drone navigation policies on various tasks in simulation using event-based images and transfer them to the real-world.

Offline-to-Online (model-based) Reinforcement Learning Transfer and Finetuning for Vision-based Robot Control - Available
Description: Vision-based reinforcement learning (RL) is often sample-inefficient and computationally very expensive. One way to bootstrap the learning process is to leverage offline interaction data. However, this approach faces significant challenges, including out-of-distribution (OOD) generalization and neural network plasticity. The goal of this project is to explore methods for transferring offline policies to the online regime in a way that alleviates the OOD problem. By initially training the robot's policies system offline, the project seeks to leverage the knowledge of existing robot interaction data to bootstrap the learning of new policies. The focus is on overcoming domain shift problems and exploring innovative ways to fine-tune the model and policy using online interactions, effectively bridging the gap between offline and online learning. This advancement would enable us to efficiently leverage offline data (e.g. from human or expert agent demonstrations or previous experiments) for training vision-based robotic policies. This would/could involve (but is not limited to) developing methods for uncertainty estimation and handling, domain adaptation for model-based RL, pessimism (during offline training), and curiosity (during finetuning) in RL methods.
Goal: Develop methods for transferring control policies learned offline to the online inference/finetuning regime.

Hierarchical reinforcement learning for 3D object navigation tasks - Available
Description: This project aims to simplify the learning process for new drone control tasks by leveraging a pre-existing library of skills through reinforcement learning (RL). The primary objective is to define a skill library that includes both established drone controllers and new ones learned from offline data (skill discovery). Instead of teaching a drone to fly from scratch for each new task, the project focuses on bootstrapping the learning process with these pre-existing skills. For instance, if a drone needs to search for objects in a room, it can utilize its already-acquired flying skills. A high-level policy will be trained to determine which low-level skill to deploy and how to parameterize it, thus streamlining the adaptation to new tasks. This approach promises to enhance efficiency and effectiveness in training drones for a variety of complex control tasks by building on foundational skills. In addition it facilitates training multi-task policies for drones.
Goal: Develop a hierarchical RL framework that leverages a library of low-level skills. The latter can be either learned using interaction, discovered from offline data, or designed.

Incorporating expert data into model-based reinforcement learning - Available
Description: Model-based reinforcement learning (MBRL) methods have greatly improved sample efficiency compared to model-free approaches. Nonetheless, the amount of samples and compute required to train these methods remains too large for real-world training of robot control policies. Ideally, we should be able to leverage expert data (collected by human or artificial agents) to bootstrap MBRL. The exact way to leverage such data is yet unclear and many options are available. For instance, it is possible to only use such data for training high-accuracy dynamics models (world models) that are useful for multiple tasks. Alternatively, expert data can (also) be used for training the policy. Additionally, pretraining MBRL components can itself be very challenging as offline expert data is typically sampled from a very narrow distribution of behaviors, which makes finetuning non-trivial in out-of-distributions areas of the robot’s state-action space. In this thesis, you will look at different ways of incorporating expert data in MBRL and ideally propose new approaches to best do that. You will test these methods in both simulation (simulated drone, wheeled, legged) and in the real world on our quadrotor platform. You will gain insights into MBRL, sim-to-real transfer, robot control. Requirements: Applicants should have a strong background in machine learning, computer vision, and proficiency in Python programming. Familiarity with deep learning frameworks such as PyTorch is desirable.
Goal: Study and propose methods for leveraging expert data in model-based reinforcement learning for quadrotor flight control.

Learning Robust Agile Flight via Adaptive Curriculum - Available
Description: Reinforcement learning-based controllers have demonstrated remarkable success in enabling fast and agile flight. Currently, the training process of these reinforcement learning controllers relies on a static, pre-defined curriculum. In this project, our objective is to develop a dynamic and adaptable curriculum to enhance the robustness of the learning-based controllers. This curriculum will continually adapt in an online fashion based on the controller's performance during the training process. By using the adaptive curriculum, we expect the reinforcement learning controllers to enable more diverse, generalizable, and robust performance in unforeseen scenarios. Applicants should have a solid understanding of reinforcement learning, machine learning experience (PyTorch), and programming experience in C++ and Python.
Goal: Improve the robustness and generalizability of the training framework and validate the method in different navigation task settings. The approach will be demonstrated and validated both in simulated and real-world settings.

IMU-centric Odometry for Drone Racing and Beyond - Available
Description: Our recent work has shown that it is possible to estimate the state of a racer drone only using a low-grade IMU. This project will build upon our previous work and try to extend its applicability to scenarios beyond racing. To achieve this goal, we will investigate an "unconventional" way of using camera images inside the odometry pipeline.

Goal: Development of an IMU-centric odometry algorithm. Benchmark against state-of-the-art VIO method. A successful thesis will lead to the deployment of the proposed odometry algorithm on the real drone platform. We look for students with strong programming (C++ preferred), computer vision (ideally have taken Prof. Scaramuzza's class), and robotic background.

Navigating on Mars - Available
Description: The first ever Mars helicopter Ingenuity flew over a texture-poor terrain and RANSAC wasn’t able to find inliers: https://spectrum.ieee.org/mars-helicopter-ingenuity-end-mission Navigating the Martian terrain poses significant challenges due to its unique and often featureless landscape, compounded by factors such as dust storms, lack of distinct textures, and extreme environmental conditions. The absence of prominent landmarks and the homogeneity of the surface can severely disrupt optical navigation systems, leading to decreased accuracy in localization and path planning.

HDR NERF: Neural Scene reconstruction in low light - Available
Description: Implicit scene representations, particularly Neural Radiance Fields (NeRF), have significantly advanced scene reconstruction and synthesis, surpassing traditional methods in creating photorealistic renderings from sparse images. However, the potential of integrating these methods with advanced sensor technologies that measure light at the granularity of a photon remains largely unexplored. These sensors, known for their exceptional low-light sensitivity and high dynamic range, could address the limitations of current NeRF implementations in challenging lighting conditions, offering a novel approach to neural-based scene reconstruction.
Goal: his project aims to pioneer the integration of SPAD sensors with neural-based scene reconstruction frameworks, specifically focusing on enhancing Neural Radiance Fields. The primary objective is to investigate how photon derived data can be utilized to improve scene reconstruction fidelity, depth accuracy, and rendering quality under diverse lighting conditions. By extending NeRF to incorporate event-based data from SPADs, we anticipate a significant leap in the performance of neural scene synthesis methodologies, particularly in challenging environments where traditional sensors falter.

Dynamic occlusions are particularly challenging because of the continuously changing pattern. This project aims to leverage the unique capabilities of event-based vision sensors to address the challenge of dynamic occlusions. By improving the reliability and accuracy of vision systems, this work could benefit a wide range of applications, from autonomous driving and drone navigation to environmental monitoring and augmented reality.
Goal: The goal of this project is to develop an advanced computational framework capable of identifying and eliminating dynamic occlusions from visual data in real-time, utilizing the high temporal resolution of event-based vision sensors.

Develop an RL environment for GoKart racing - Available
Description: The student will develop an RL training environment that is able to train an agent to race in a race track. This environment will support different RL algorithm (PPO, SAC, etc). The student will first start with building the environment itself, including the track and a potential ‘car’ with its basic dynamics. After this, the student will develop a reward function that is able to take the car to its limits of handling, similar to what we have in the drones.
Goal: At the end of the project, the created environment will be able to train a car agent that is able to race time-optimally through a track
Contact Details: The project will be supervised by both Professor Emilio Frazzoli and Professor Davide Scaramuzza's groups. The experiments will take place at the Winterthur testing ground, utilizing our fleet of autonomous racing karts.

Vision-based Navigation in Dynamic Environment via Reinforcement Learning - Available
Description: In this project, the goal is to develop a vision-based policy that enables autonomous navigation in complex, cluttered environments. The learned policy should enable the robot to effectively reach a designated target based on visual input while safely avoiding encountered obstacles. Some of the use cases for this approach will be to ensure a safe landing on a moving target in a cluttered environment or to track a moving target in the wild. Applicants should have a solid understanding of reinforcement learning, machine learning experience (PyTorch), and programming experience in C++ and Python.
Goal: Develop such a policy based on an existing reinforcement learning pipeline. Extend the training environment adapted for the task definition. The approach will be demonstrated and validated both in simulated and real-world settings.

Learning Rapid UAV Exploration with Foundation Models - Available
Description: In this project, our objective is to efficiently explore unknown indoor environments using UAVs. Recent research has demonstrated significant success in integrating foundational models with robotic systems. Leveraging these foundational models, the drone will employ learned semantic relationships from large-world-scale data to actively explore and navigate through unknown environments. While most prior research has focused on ground-based robots, this project aims to investigate the potential of integrating foundational models with aerial robots to introduce more agility and flexibility. Applicants should have a solid understanding of mobile robot navigation, machine learning experience (PyTorch), and programming experience in C++ and Python.
Goal: Develop such a framework in simulation and conduct a comprehensive evaluation and analysis. If feasible, deploy such a model in a real-world environment.
