I'm far enough along in my project to post some pictures of my Fit-Phidget rover. It is based on a Lynxmotion A4WD1 v1 kit (http://www.lynxmotion.com/Category.aspx?CategoryID=111), a Fit-PC Slim PC (http://www.fit-pc.com/fit-pc1/)as the brains and uses a Phidget servocontroller (http://www.phidgets.com/products.php?category=11&product_id=1000)to control the motors. A Linksys wireless-G webcam provides the video. My program running on the controlling PC takes input from a PS2 joystick and communicates with the phidgets webservice on the Fit-PC, driving the wheels in tank-mode.

The body houses the four motors, the Sabertooth motor controller, the phidgets board and a Zagros power distribution board under all the wires.

The Fit-PC sits on the top of the body.

The upper deck holds the lithium-ion battery pack which powers everything through the distro board and the webcam.

It's my first robot and it's just a start, so be gentle.

Nice! You may want to clean up the wiring inside since it'll make it a lot easier to track down wiring problems. From the outside though it looks really clean.

why the wireless cam if you have a PC onboard? Couldn't you have the PC host the video on a standard cam?

It turned out that the Fit-PC is way too underpowered to process the video. I'm already thinking about going to an Atom-based mini-itx board.

Once I finalize all the components, I'll work on cleaning up the wiring.:happy:

Looks very nice.

It's a nice looking bot you have there.

Did you find a replacement? I'm looking at using a fit-pc2 (Atom 1.6) for a vision based robot project. That would be a bit faster. I've also been considering a Beagleboard, but they're all sold out right now.

Thanks!

Actually I'm still using the fit-pc because of its small size. I'm using a Logitech 9000 webcam and, as long as I limit the resolution, the fit can handle it. The fit-pc2 would be even better.

The size was important to me because I upgraded the rover chassis to the Lynxmotion v2. With the bigger chassis, I was able to fit (pun intended) everything into one box - the motors and controller board, the phidget servo controller, a power distro board, the fit-pc and a 8000 mAh lithium polymer battery pack to power the whole thing.
