We are building on top of established robotics joints, such as the one used in the MIT Mini Cheetah [1]. However, we are fully customizing its design with our own electronics and novel hardware aspects through integration of elastic elements.

We want to find the best way to exploit all novel actuator features in control. We have designed a first prototype and want to work on control implementation and testing through an adaptation for a highly dynamic use-case (e.g., vertical jumping or throwing).

Student work is planned to span prototyping for finalizing the test setup alongside robotics control concepts for exploitation of system elasticities. A promising research direction is emulating VSA behaviour [2] through the interaction of the mechanical spring and motor control.

We are looking for candidates with a strong interdisciplinary focus and interest in practical work, with an excellent academic record.

What you will gain:

• Experience in Modeling and Control of Robotics systems
• Experience building, prototyping
• Best design practices
• Insights into our System Development and access to our community

Requirements from candidates:

• Strong in Control Methods
• Any CAD software for the part designs (Solidworks, Fusion 360, etc.)
• Matlab skills
• Basic skills in Electronics
• Plus are:
  • Understanding how Motors work
  • Familiarity with GIT
  • Working skills in Ubuntu operating system
  • Embedded systems development

To apply, you can send your CV, transcript and short motivation to Vasilije Rakcevic for initial review (application deadline - September 10).
