This movie shows some unique feature of STAR (Sprawl Tuned Autonomous Robot). The biomimetic robot is 3D printed and controls its sprawl angle control which allows him to perform many maneuvers to overcome obstacles. In the movie the robot sprawls down and goes under a door then sprawls up.
It can run at all speeds up to 5.2m/s (43 body lengths per second) on smooth surfaces while steering is on (i.e. it can be controlled to run in straight line or turn). The legs slide to the side in order to reduce collisions with the ground which allow for better stability and steering control.
The robot was designed by David Zarrouk, Andrew Pullin, Nick Kohut and Ronald Fearing at the Biomimetic Millisystems Lab, UC Berkeley. (Reference: ICRA 2013)
This is the third version of our robot, we made some mechanical improvements. We added fiber reinforced rods to reduce collision damage at high speeds.
