The Soft Robotics Lab within the Institute of Robotics and Intelligent Systems at ETH Zurich is inviting applications for Postdoctoral researchers to join and steer our research efforts in the advanced modeling of soft robots. Our lab's goal is to build, model, and control robots in a fundamentally different way, so that they become more flexible, dexterous, capable, and adapt better to their environment. The lab showcases its research in design and algorithms through several real-world applications including a robotic fish for underwater locomotion, soft robotic hands for pick-and-place tasks, and multi-segment arms for dynamic object manipulation.
Robots made of soft materials, so-called soft robots, well surpass the limited degrees of freedom that rigid systems possess and therefore potentially offer adaptable and inherently safe ways of achieving versatile forms in locomotion and manipulation. Soft robots can homogeneously combine actuation, sensing, and structure in one composite. In our lab, we develop continuously deformable robots using compliant materials and intelligent sensors whose properties resemble those of living organisms. These soft robots can be used more flexibly and are safer than conventional ones when interacting with humans and surroundings. The vision of the project is to evolve soft robotic systems from the realm of proof-of-concept, one-off prototypes into capable and reliable machines that can morph to tackle challenging tasks in manipulation and locomotion.
One of the core challenges to overcome and realize the project's vision is the development of soft robotic "brains". Robotic “brains” are needed to fully exploit the unique properties of soft robots and make them useful for real-world applications. The controllers within a robotic brain relies on a fast and representative model of the robotic “body” that is to be controlled. However, accurately modeling a deformable material under controlled actuation and/or interacting with the environment is complex and computationally slow because of the infinite dimensions of the material. Modelling and control approaches used for traditional robotic systems made of rigid links do not readily extend to soft robots. Therefore, it is important to develop new models and controllers for soft robots to enable them to perform challenging locomotion or manipulation tasks that surpass the capabilities of rigid robots.
You develop computationally efficient physics models that capture only the relevant degrees of freedom of a soft robot as defined by their tasks. In your research, you will learn to describe non-linear deformations of hyperelastic materials in real-time. You pursue dual research tracks to achieve a universal soft robotic modeling framework: For symmetrically-shaped robots, you develop minimal parameter methods sufficient enough to capture the dynamics and impedance of the deformable structures while being computationally efficient. For robots of irregular shape, you develop large scale finite element methods and make those models tractable by expanding on techniques such as model order reduction with state observers and deep learning methods. You advance the state of the art of the current modeling approaches used in the dynamic closed-loop control of soft continuum robots. You continuously design, simulate, and test your modeling algorithms on your deformable robots so that they become more able to dexterously interact with an inherently deformable world.
Your system modeling and model-based control approaches will be design-agnostic and user-friendly to facilitate broad adoption in the robotics community. You will conceive and create an open-source modeling framework for soft robots. The development of such a framework will be accelerated through active collaborations with other researchers working on numerical simulations of physical systems such as SOFA and on toolboxes for dynamical systems modeling such as Drake.
Next to your research efforts, you are a passionate mentor and a patient educator. You are outstanding in mentoring students performing their semester projects or thesis works in our lab. You will also be involved in the teaching of graduate classes in soft robotics, modeling, controls, and machine learning.
You are extremely curious, very driven, highly independent, and you want to make a real difference with your research. You work best when you are in a team, you are respectful and thrive when you can collaborate with others and provide support. Through your prior research experiences, you have proven your skills in:
A deep foundational understanding of physical modeling and machine learning methods is essential for the successful completion of this proposed postdoctoral research project. It would be greatly advantageous if you are already proficient in C++ and Python. You collaborate well with your lab mates and other research labs, you are a resourceful asset for other researchers and students, and you can make efficient use of the provided support from R&D experts, scientists, engineers, and doctoral students with background in materials science, mechanical engineering, electrical engineering, computer science, and physics.
