4-Servo Walker
Neat little bot uses four 9-gram servos and short legs to walk. http://www.youtube.com/watch?v=jh1wQtIjbTw&NR=1 Straight walking only, no turning demonstrated.
It has a curious gait: each leg pauses mid-stroke in a vertical position. The builder programmed this, on purpose or accidentally. I found that same off-brand uC can drive 8 servos pretty smoothly: http://www.youtube.com/watch?v=HSLktpOkrGs
I've stockpiled several (8 or more!) of these $1 China servos in anticipation of building a simple walker. Here's a baseline for future comparison.
