The Mechanics
The robot is made exclusively from brushed, or black anodized aluminum servo brackets from Servo Erector Set. It also includes an electronics carrier made from ultratough lasercut Lexan.

The Servos
Manufacturer is providing the walker with Hitec HS422 servos. Due to the robot's light weight, these servos work well.

Powering Options
As with any walking robot, weight is a major concern. The best approach is to keep the weight to an absolute minimum. Manufacturer recommend using the 6.0 Volt NiMH 1600mAh Battery Pack and the Universal Smart Charger.
