BEAM walker circuits The whole enchillada... So far, I host eight walker circuit pages locally: Wilf Rigter's 1-motor uCrawler Another on Wilf's P5v2 5-motor walker circuit A hexapod circuit A 2-motor walker circuit that uses unmodified hobby servos A series of quad op-amp designs by Wilf A phototropic 2-motor walker (a bit complex) by Wilf A solarized phototropic walker, also by Wilf Tom Gray's response to a challenge in the "Junkbots" book Meanwhile, for your 'bot building pleasure, here are links to walker circuits elsewhere: Complete walker freeform by Sebastiaan van Vliet 1 page, 13 images / 32 KBytes inline Bicore-based two-motor walker with reverse; really complete tutorial with fantastic graphics. Complete Master-slave bicore by Ian Bernstein 1 page, 1 image / 142 KBytes inline Bicore-based two-motor walker with reverse switch; shares page with many other circuits. 4 Nv uCore by Chiu-Yuan Fang 1 page, 17 images / 264 KBytes inline Two-motor walker; schematic is down near the bottom of the page. Reversing Microcore by Wilf Rigter (now offline, was here ) 1 page, 1 image / TBD KBytes inline Reversing PNC-free microcore with driver [74HC14, 74xx240]. 6 Nv uCore by Chiu-Yuan Fang 1 page, 13 images / 322 KBytes inline Three motor walker; schematic is down near the bottom of the page. Microcore walker by Terry Newton 1 page, ASCII circuit diagrams A reversing microcore with drivers [74HC14, 74HC245]; diagrams are very readable for ASCII "art." Walker 2:14:1 by Eric Seale 1 page, 7 images / TBD KBytes inline A simple non-reversing (74*14) quadcore with 74*245 drivers; schematics, layouts, PCB designs, parts list. Walker 2:14:2 by Eric Seale 1 page, 7 images / TBD KBytes inline A simple (74*14) quadcore with reversing 74*240 drivers; schematics, layouts, PCB designs, parts list. For more information... The Bestiary pages on walkers start here.
