Solarwalker 1V0

Home Beam Bots Links

Solarwalker1V0 Likely the simplest solar walker that can be made, a 1381J Solar engine with a master/slave Bicore. All on one IC (74AC240) that also direct drives the Nihon gear motors. The SE drives the enables low as it fires and off it goes.

Completed- Sept/2001

It takes about a minute to charge the SE up to 3 Volts and then 20 to 30 seconds there after. The enable is triggered at the 3 Volt level and driven high at about the 2.7 Volt level. So no real problem for the two series 1F 2.5v Capacitors.  [click image for larger view]

The leg design was inspired by pictures of the B.I.O. Bugs that Solarbotics had up a long time ago. For each charge it takes about 4 - 6 steps so not very fast, but left to its own devises it gets a fair distance it a few hours. [click image for larger view]

The longest, and most difficult, part of making  this walker was trying to make the frame strong and light, every frame element and the legs are various sized paperclips. [click image for larger view]
