Nice toy!
I am also working on a robot using gumstix cpu board and RX-64 servos. Can I ask what interface you use between gumstix and rs485? It seems to me that a USB to rs232/rs485 converter would add some serious delays. The TI ARM chip does have a couple of UARTS but they don’t seem to be designed for auto rs485 flow control. The only options I see are:
1) to hack the uart driver to control RTS pin in real-time but driver coding is still a little above my head…
2) use SPI-rs485 converter chip but that is more hardware hacking than i’d like to get into.

Any suggestions/comments would be greatly appreciated.

Rob-

Total retail parts cost is a bit over $10,000 USD… but that’s not factoring in the hundreds of hours I’ve dropped into it over the past 6 months.

Wow that is cool, you could probably sell kits for that, it would be cool to have one.

How much has the build set you back so far?

You has GOTS to put a small GI Joe or some such in the cockpit.

That is some sweet electromechanical work!
