Georgia Tech's Sand-running robot

Georgia Tech's Sand-running robot

Postby adam.klaptocz on 06 Jun 2008, 09:27

Teams at Penn University and Georgia Tech have tackled the problem of sluggish robot movement on sand. Following a study of the locomotion of lizards on the ground and in water, they have built a six-legged robot with curved, C-shaped limbs instead of wheels.

This guy looks very similar to Boston Dynamic's RHex: http://www.bostondynamics.com/content/s ... ction=RHex - any connection?

Yes, as far as I know it's the same bot. I think the Crab Lab team at Georgia-Tech helped optimize the movement in sand based on a study (http://www.physics.gatech.edu/research/ ... /index.htm).

This reminds me of Roger Quinn's Wheel-Legs ( Whegs : http://biorobots.cwru.edu/projects/whegs/ ).

According to the last link the RHex actually preceded Quinn's Whegs... In any case the concept seems very versatile - one of Metin Sitti's Waalbots shows another application of the same idea: http://nanolab.me.cmu.edu/projects/waal ... -leg.shtml

The RHex is even more amazing than I initially thought! Folks over at McGill university have gotten the robot to walk on 2 legs:



A bipedal RHex! :D

Video below; skip to about halfway for slow motion!




Make sure to also check out the recent Robots interview with Bob Full, who is the biologist behind these robots!
