Hobby Robots Can Jump
Writing by Evan Ackerman on Monday, 14 of December , 2009 at 1:24 am
Getting a humanoid robot to jump is no easy task <... You need to have very powerful servos capable of very high acceleration, something that until recently wasn't readily available to hobbyists. Not in a small package and relatively reasonable price, anyway. This robot is able to jump some 3cm into the air using the new (as of August 2009) Kondo KRS-2552HV in its legs; these servos put out 14kg*cm of torque and can rotate 60 degrees in 0.14 second. They're no RX-64, but they only cost about $80 each as opposed to $300.
The upshot of all this is that servos are getting faster, stronger, and cheaper, which means that we’ll be seeing more robots capable of feats like running and jumping.

The designer really should try to incorporate some suspension mechanism into the legs – to store energy for the next jump, but mostly to alleviate shock from the other servos.
