Beam style bot. Introduced by Mark Tilden. Uses 5 modified servo motors. Uses bicore to drive a 4 Neuron string (74hc14). Opposed to a 4 Neuron loop. Alot more reliable. Reverse sensor using 74HCT240. 74LS245 used as motor drivers. Waist motor uses a 6 Darlington transistor h bridge. I plan on adding turn sensors and photodiodes for sight later on. Power is supplied by 5 1.5v 1600Ma nicads at 7.5 volts. Takes very large steps and get get over many obstacles. I had to redo the electronics twice and the frame about 4 or 5 times because the the walking gait wasn't quite right. Very frustrating. Plus the first set of batteries only lasted a few minutes so I replaced those too. I think they were recharged wrong. I want to wait and see how long this set last before having to be recharged before adding any sensors. I am currently working on a monster 8 servo walker using microcore technology with a new many new circuit ideas I recently came up with. I also plan to add a Basic stamp to and more functionality.
