Well, I found some interesting code on the internet for a serial driven servo controller, for up to 8 servos, on a single pic 16c54A ucontroller. Kickass. Unfortunately, there was no schematics, circuit board, or anything else for the thing. Not that that is really a problem.

I have built the schematics and pc-board for the controller, and managed to squash the whole thing into a 1.65" x 1.95" space. Just supply 6 volts and you are good to go. I will be posting the entire thing on my site at RantTV later on today. I tested on a breadboard, but I still need to test the actual board, so don't build it just yet eh?

The code itself (written by Mark Sullivan, available at http://www.markwo rld.com/servo1.asm) is capable of running 8 servos, off of a 9600 bps 8n1 serial port. It can run up to 19,200 or down to 300 bps. This should help me get my legs moving.

Well, I headed on down to the alleged meeting of the Vancouver Robotics Club on Sunday. 10:00am came, then 10:30, then 11:00.....

No members.

Lot's of other people who were curious about the club came out, and we talked for a bit about what we were all doing, but in the end, no members. So we left. I took down all the non-members emails and I am hoping to form a Vancouver Robotics Club splinter faction ;)

Hmm, what to post... I have some interesting ideas for control systems, especially a feedback motion control system that allows for sub-millimeter positioning and very high speed using a pneumatic cylinder. I have used this system to great effect for an automotive application. I have wanted to play with it for a leg actuator for a while now, but never have enough time. Drop me a line through my homepage if you are interested in learning more...
