Bio Robotics

Research Group

Our Motivation

The research group Bio Robotics at the Chair of Micro Technology and Medical Device Technology (MiMed) examines the feasability of organic systems to replace physikal components in the field of robotics. We want to explore and develop devices or systems in which biological components work in symbiosys with physical ones. For this purpose, we are working in the field of mechanics, kinematics, electronics and information technology. Particularly, the potentialities of rapid manufacturing (e.g. selective laser sintering) are systematically explored.


We want to research robotic systems that are biohybrid systems that generate forces and torques through muscles made of biological cells encapsulated in exoskeletons or skin-covered tissue systems that can be electrically controlled. The skeletons consist of mechanisms that can convert simple linear motions into complex spatial motions with high precision.
The future of robotics consists of systems, taking their energy from food, converting the energy into force via cells, and can still being controlled electrically.
The question is, up to which point it is possible to arrange biorecators around the muscle cells and with which skeletal structures mechanical movements can be achieved.


The chair posseses various manufactoring facilities for the production of functional models and prototypes. Such as a precision engineering shop floor. Notable facilities include:

  • EOS Formiga 100
  • CNC 5-axis milling machine (Deckel)
  • Z-corp Z-510
  • Trotec Speedy 400 flexx laser cutter
