STAR is a bioinspired robot which can run at 5.2m/s

Published on Feb 21, 2013


STAR is a six legged bioinspired, 12cm long, Sprawl Tuned Autonomous Robot which can vary its sprawl angle in order to adapt to different surfaces.
The robot, can achieve legged performance over rough surfaces and obstacles, using a high sprawl angle, and nearly wheel-like performance over smooth surfaces for small sprawl angles. By changing the sprawl angle it can climb over obstacle or crawl underneath them.
STAR can run at 5.2m/s (43 body lengths/second, Froude number 9.8) over a smooth surface which makes it the fastest untethered crawling robot.
STAR was developed at the Biomimetic Millisystem Lab, UC Berkeley, by David Zarrouk, Andrew Pullin, Nick Kohut and Ronald Fearing. (IEEE ICRA 2013)

Acrobatics of STAR.V3, UC Berkeley, a high speed 3D printed robot

Published on May 24, 2013


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.
