Here’s another cool tiny robot from MiddleCreekMerchants.
This is a very small all-analog real working robot. It walks forward a little less than 1 inch per Second. The robot moves in psuedo-organic behavior.
Two Servos twist left then right in a pattern which places each foot on the ground at different times in order to give him a forward stride.
The robot has a NiMh battery which runs for about 15 minutes on a full charge and charges via a USB cable in about 5 minutes.
This one recharges using mini-b USB cable (for cameras and cellphones).
