Meet Johnny 5. 

He's an autonomous humanoid robot that is 53 cm tall, weighs just about 1 kg, and has 20 servo motors each capable of 14 kg*cm of torque. On board, custom circuit boards tie together four powerful microprocessors: two 500 MHz Blackfin DSPs (one for each of the two cameras in the head for stereo vision), one 600 MHz Gumstix Overo Air linux microcomputer, and one 20 MHz motion controller board. 

How did you make him?
We purchased a Kondo KHR-3HV Humanoid Robot kit from Kondo in Japan (http://kondo-robot.com/sys/). We then modified the torso to accommodate the computers, larger battery, and related electronics, and created a pan-tilt head assembly to accommodate the two cameras. The electronics consist of a couple of custom PCB boards we designed that integrate and power the two 500 MHz Blackfin computers with the Gumstix. 

How much would it cost ME to make one?
Only $2,500 USD in mechanical / electronic parts and a LOT of free time.

Where can I find out more?

that's not inexpensive; unless you are rich

If you are looking for cheap servos (seems to be most people's concerns) check out hobbyking.com. I use them for all of my RC servos and they sell good all metal gear servos with fast reaction times for CHEAP.

One of the servos that appears to meet the torque requirements of the bot.

i dont see $2.500 as inexpencive :/

$2,500 is relatively inexpensive. Without a complete Instructable, the really expensive part is attaining sufficient knowledge of the following subjects (at least) to recreate this through original research:

  • Machine Vision
  • Machine Learning
  • Genetic Algorithms
  • Humanoid Motion Planning
  • Robotics
  • Engineering
  • Electronic Engineering
  • Programming

$2,500 for materials suddenly seems cheap doesn't it? :)

well im still looking for summin alot cheaper XD
