Roz - Walking Fast and Smooth

Here's a short video showing the improved gait:
I'm planning on swapping out the Arbotix board for a gumstix Overo Earth, which I happen to have sitting on my desk thanks to my brother Dave. That board will run Squeak, and I've already got the IK and gait code from my friend Mike Ferguson ported into Squeak.

I've also got a new leg design prototyped, with a compliant spring. Once I add a sensor to this leg, I will be able to start looking at handling terrain compliance, which will allow Roz to handle uneven terrain (like what you find outdoors).
Lots of things to do, lots of places to go....

Neat leg design. I also find it interesting that you are upgrading the processor so soon. Earlier I had assumed you would run the Arbotix in tandem with something more powerful. I am curious to see how easy it is to interface a Gumstix board with the AX-12 servos.
I appreciate the updates, keep us posted!

Its very easy - I just plug in my USB bus interface board, and talk to the bus directly...

That's so easy it almost seems like you are cheating. =)
What sort of interface will you normally have with Roz? A remote control of some sort or maybe a PC running a console application?

Roz is going to be very autonomous. I will have a simple web interface with him, since he will be running a web server, and I can display those pages (at least while I'm at home) on my iPod touch. That will allow me to do simple things like set missions and change settings.
For more complex things, I will be able to communicate directly (over a socket) from my development machine.

Since the Overo Earth doesn't have a wireless NIC built in, what are you using for your network connection?

That's a Trendnet wifi dongle plugged into a very small 4-port USB hub.
