It's November 29, 2011, I have been collecting parts for this Robot for about a year, I started the build about November 1, 2011.

@ PaulJD, per request I have uploaded a video of the robot. The program I am using is fairly simple, it is very simular to code I used in my last robot, but this robot has a lot more servos. I put the current code together recently in my spare time over a few days.

@ Geir Andersen, yes the tracks are expensive, they are from Lynxmotion at http://www.lynxmotion.com/c-120-no-electronics-kit.aspx . The Ping sensor will be useful in the future when the robot is running in the autonomous mode, it will be used to make sure the robot doesn't run  into some thing like a table top. I will need to add several other sensors near the floor. If you watch the video you can see that the robot can look around 360 degrees with the head ping sensor.

Great looking robot. You don’t state the current price but the tracks seem expensive.

One question, is the ping sensor useful mounted so high up or is it just for cosmetics?

It looks wonderful.  Well Done.

I would love to see a video of those motions and commands.    has the programming been in development for a while also, or did it begin lately?
