Researchers designed lab-grown muscle and its flexible scaffold together

These robots have real muscles, and they’re finally making big moves. Researchers at ETH Zurich have developed muscle actuators that flex strongly enough to enable small robots to jump, swim, walk and grasp.

Quick read

A research news article from ETH Zurich describing centimetre-scale biohybrid muscle actuators jointly designed with their soft hydrogel scaffolds. Visit to learn how computer co-design and 3D-printed scaffolds enabled visible muscle-driven movements like jumping, swimming, walking and grasping.

  • Muscle and hydrogel scaffold were co-designed via computer simulation
  • Bioactuators (~1.5 cm) show up to 11x greater range of motion
  • Demonstrations include jumping, swimming, walking and grasping
