I will get some details today and make a video of them in action. They do use motors and have clutches that you can tighten to increase strength (less slipage) that are used to protect the gears. It does have rocker control buttons - up is one way and down is another so I believe they already have built in H bridges. The unit takes 4 D cell batteries to operate so I also assume the voltage to be about 5 volts.

You control the opening and closing of the gripper, rotation of the wrist, movement of the elbow and shoulder, and rotation of the arm on its base. The completed arm can lift up to approximately 4.6 ounces (130 grams).

IT looks very cool.just i dont need it motors are sometime has more torque and very easy to convert to servo only need a cheap servo board and feedback pot,i make them all the time servo board is about $2 from futuba S3003 servo from china and pot is a 5k pot

thinking you can easy change the motors for a higher torque

Awesome Dave! your comment about sleeping in the spare bedroom is funny, cause my wife thinks I am building a sexbot ummm no. Good to hear that there's lots of interest for R2. The whole idea of hacking a platform is verry appealing......I know DJ has something to unveil very soon! "Anticipation is making me wait"(to the tune)

Ok. I'llsend an email in the morning (or afternoon more likely) when I am awake and sober so we can talk price. Interested in both arms.
