Yesterday two of the larger packages arrived, which include the servos and the chassis. Naturally I had to start putting it together. You can see in the pictures my arduino powered servo centering jig, I figured it would be a good idea to have all of the servos centered before I start putting them all into the chassis.

I was pleasantly surprised to find that the servos themselves are of decent quality, as advertised they have all metal gears, although they don't quite reach the 180 degrees of motion they advertised. 

While I would love to have started using the LiPo battery the regulator hasn't arrived yet, so I used a wall wart to provide the 5V for centering the servos.

I looked into using openCV with the PI and from what I can tell it may not be fast enough to perform the object avoidance that I was hoping for, even if that's the case I can still use it as a piloting camera over wifi to get that "I'm riding in a walking robot" feeling.
