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.

Image

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.

Image

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.

Image

Reversing Microcore by Wilf Rigter (now offline, was here )
1 page, 1 image / TBD KBytes inline

Reversing PNC-free microcore with driver [74HC14, 74xx240].

Image

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.

Image

Microcore walker by Terry Newton
1 page, ASCII circuit diagrams

A reversing microcore with drivers [74HC14, 74HC245]; diagrams are very readable for ASCII "art."

Image

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.

Image

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.
