Dude, awesome robot!
I really like the movements and the design as well.
What's that sensor on the head? Is it a camera?
That bot is using an Atom Bot Board II with Atom-pro 28m and a Serial servo controller ( SSC32 )
controlling 18 servo's for the legs 1 for the head panning.
It PS2 wireless controlled or Autonomous
In the head is ( Yes ) a camera which is sending streaming video to my PC to the program Robot Realm ( free version ) then robot realm sends back serial data VIA blue tooth to the SSC32 to control the head. The camera will also respond to near objects and through Robot Realm will send serial data back to the bot to move away from it or go towards it whatever I program it to do. The bot also has an accelerometer/tilt sensor which in conjunction with the Atom pro program gives it that realistic looking walk.
Some of you may have noticed that the actual head is from the original Rob the robot made by nintendo it works great for my projects I have a few kicking around, inside the head is a wireless cam, Sparkfun blue-tooth, small servo, and a bright led.
