Biped BRAT (BotBoarduino / PS2) BRATCCU
All mechanical parts
6 servo biped walker (servo not included)
Can be modified with the Servo Erector Set
The Lynxmotion Biped BRAT Kit (No Servos or Electronics) BRAT-BLK is a 6 servo biped walker featuring three degrees of freedom (DOF) per leg. The robot can walk forward or backwards and turn in place left or right with variable speed. It can even do lots of Robo-One style acrobatic moves.
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 ultra-tough laser-cut Lexan.
The Servos
The manufacturer is providing the walker with Hitec HS-422 servos. Due to the robot's lightweight, 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. Manufacturers recommend using the 6.0 Volt Ni-MH 1600 mAh Battery Pack and the Universal Smart Charger.
Controlling the Biped
The robot is available in two basic configurations, Animatronic (tethered connection to a PC) or Autonomous (controlled by the onboard Basic Atom Pro processor). The autonomous version includes the Bot Board II and the Basic Atom Pro processor.
