Take a peek at (the rather crummy, I'm afraid) pictures at

It's an insect thingy that works a bit like that. It's a bit bulky since it
uses universal joints to make the leg rods "bend."

There has got to be hundreds of little walkers in the desk drawers of every

can talk clever! (1)

However, I'd dispute the cleverness of mine :-)

The two motors aren't synchronised, and when they get out of phase, the
robot rocks back and forth until bits fall off. I guess I could use
angle/rotation
sensors to work out where one side is relative to the other, but that's a
job for
another day/month/year...

(...) Actually you could use the differential technique discussed before to measure their phase directly, if you're short of sensors (as one is...). stephen (26 years ago, 7-Dec-98, to lugnet.robotics)

(...) John Willoughby has made a different version of the same walking technique at (URL) uses only one degree of freedom, but using two motors, one for each side should be easy. Perhaps this construction is more rigid? Fredrik (26 years ago, 8-Dec-98, to lugnet.robotics)
