The Sand Flea robot rears up in preparation for launch
When we first spied Sandia National Laboratories' Precision Urban Hopper Robot back in 2009 it employed combustion-driven pistons to propel it into the air and allow it to clear obstacles. In the same year Sandia handed development of the jumping robot over to Boston Dynamics, the company behind robots including PETMAN, BigDog and CHEETAH. Now known as Sand Flea, Boston Dynamics has released new video of the robot showcasing an updated jumping mechanism.
