BioBiped Project (2009 - 2014)

biologically inspired robots with human-like musculoskeletal leg structures

BBp3 The vision of humanoid robots which mimic abilities of humans has inspired researchers for decades. Yet transferring human abilities into a robotic counterpart has proven to be highly challenging in most cases. The recently launched BioBiped project aims at realizing human-like three-dimensional running, walking and standing and herewith allowing the free selection of speed and gait. For achieving this goal, the SIM Group of TU Darmstadt and the Locomotion Laboratory of TU Darmstadt cooperate in this project.

Integration of biomechanics research in the concept of the development of versatile, robust and energy-efficient bipedal robots may represent an essential tool to get a step closer to robots with human-like locomotion capabilities.

In 2010, BioBiped1 was presented as the first of a planned series of musculoskeletal robotics platforms being developed for the purpose of investigating and evaluating hypotheses and results from biomechanics of human locomotion in robotics and their transfer to new robotic platforms.


Alternate hopping on moving treadmill


BioBiped 3 robot was designed and manufactured in 2014-2015. In this robot active mechanisms (SEA) were developed for the biarticular thigh and shank muscles. Their adjustment results in better synchronization of different limbs, reducing energy consumption using the system natural dynamics and more importantly, helps benefit from separation of axial and rotational direction of leg force to facilitate locomotion control. A simple experiment is presented in the following video.
