Project Database

This page contains the database of possible research projects for master and bachelor students in the Biorobotics Laboratory (BioRob). Visiting students are also welcome to join BioRob, but it should be noted that no funding is offered for those projects (see https://biorob.epfl.ch/students/ for instructions). To enroll for a project, please directly contact one of the assistants (directly in his/her office, by phone or by mail). Spontaneous propositions for projects are also welcome, if they are related to the research topics of BioRob, see the BioRob Research pages and the results of previous student projects.

Amphibious robotics

756 – Imitating animal behavior on a bio-inspired robot with reinforcement learning
Show details
Category:semester project, master project (full-time)
Keywords:Experiments, Learning, Programming, Robotics, Simulator
Type:15% theory, 10% hardware, 75% software
Responsibles: (MED 1 1611, phone: 36620)

Description:

Introduction

This project has been taken.

The spinal cord in many vertebrates contains a central pattern generator (CPG)[1] that can control the physical body to interact with the environment and produce diverse rhythmic motor patterns, such as walking and swimming. And amphibious robots are good biological counterparts of animals for understanding their locomotion. In this project, we would like to use the Deep reinforcement learning framework BRAX[2] in MuJoCo[3] for exploring and designing CPG controllers for a bio-inspired robot Polymander[4] and then verify the controller in real experiments.

Main Contents (PdM contents in bold)

  • Migrate the existing CPG-controller into MuJoCo Jax framework to prepare robot simulation experiments
  • Use Deep reinforcement learning to train a CPG network for Polymander to walk [, swim, and transition] in different terrains. If needed, access to EPFL scitas computing cluster would be provided.
  • Deploy the network on real robots for validation [and reduce the reality gap].

The student is expected to be rigorous and patient, have good programming skills and prior knowledge in reinforcement learning. Having taken the course CS-433 Computational Motor Control is a plus, but not mandatory. Students interested in this project could send CV, transcripts, and materials that can demonstrate project experience, if possible, to supervisors listed above.

Human-exoskeleton dynamics and control

735 – Hip exoskeleton to assist walking - multiple projects
Show details
Category:semester project, master project (full-time), bachelor semester project, internship
Keywords:Bio-inspiration, C, C++, Communication, Compliance, Control, Data Processing, Dynamics Model, Electronics, Experiments, Inverse Dynamics, Kinematics Model, Learning, Locomotion, Machine learning, Online Optimization, Optimization, Programming, Python, Robotics, Treadmill
Type:30% theory, 35% hardware, 35% software
Responsible: (MED 3 1015, phone: 31153)
Description:Exoskeletons have experienced an unprecedented growth in recent years and hip-targeting active devices have demonstrated their potential in assisting walking activities. Portable exoskeletons are designed to provide assistive torques while taking off the added weight, with the overall goal of increasing the endurance, reducing the energetic expenditure and increase the performance during walking. The design of exoskeletons involves the development of the sensing, the actuation, the control, and the human-robot interface. In our lab, a hip-joint active hip orthosis (“eWalk”) has been prototyped and tested in recent years. Currently, multiple projects are available to address open research questions. Does the exoskeleton reduce the effort while walking? How can we model human-exoskeleton interaction? How can we design effective controls? How can we optimize the interfaces and the control? Which movements can we assist with exoskeletons? To address these challenges, the field necessitates knowledge in biology, mechanics, electronics, physiology, informatics (programming, learning algorithms), and human-robot interaction. If you are interested in collaborating in one of these topics, please send an email to giulia.ramella@epfl.ch with (1) your CV+transcripts, (2) your previous experiences that could be relevant to the project, and (3) what interests you the most about this research topic (to be discussed during the interview).

Mobile robotics

754 – Vision-language model-based mobile robotic manipulation
Show details
Category:master project (full-time), internship
Keywords:Control, Experiments, Learning, Python, Robotics, Vision
Type:20% theory, 20% hardware, 60% software
Responsible: (MED11626, phone: 41783141830)
Description:INTRODUCTION Recent vision-language-action models (VLAs) build upon pretrained vision-language models and leverage diverse robot datasets to demonstrate strong task execution, language following ability, and semantic generalization. Despite these successes, VLAs struggle with novel robot setups and require fine-tuning to achieve good performance, yet how to most effectively fine-tune them is unclear, given many possible strategies. This project aims to 1) develop a customised mobile robot platform that is composed of a customised and ROS2-based mobile base and robot arms with 6DOF (ViperX 300 S and Widowx 250), and 2) establish a vision system equiped with RGBD cameras which is used for data collection, 3) deploy a pre-trained VLA model locally for robot manipulation with a focus of household environment, and 4) platform testing, validation and delivery. Excellent programming skill (Python) is a plus. For applicants not from EPFL, to obtain the student status at EPFL, the following conditions must be fulfilled (an attestation has to be provided during the online registration): [1] To be registered at a university for the whole duration of the project [2] The project must be required in the academic program and recognized by the home university [3] The duration of the project is a minimum of 2 months and a maximum of 12 months [4] To be accepted by an EPFL professor to do a project under his supervision For an internship, six months at least is suggested. WHAT WE HAVE: [1] Ready-and-easy-to-use robot platforms: including ViperX 300S and WidowX-250, configured with 4 RealSense D405, various grippers, and mobile robot platform [2] Computing resources: TWO desktop PC with NVIDIA GPU 4090 [3] HPC cluster with 1000h/month on NVIDIA A100 and A100fat : can use 1000 hours of A100 and A100 fat NVIDIA GPU every month, supports large-scale training and fine-tuning. Interested students can apply by sending an email to sichao.liu@epfl.ch. Please attach your transcript and past/current experience on the related topics. The position is open until we have final candidates. Otherwise, the position will be closed.
