About the Biped BRAT
About the Biped BRAT
BRAT stands for Bipedal Robotic Articulating Transport. The robot 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. Our combo kits include everything needed to make an operational robot, however the chassis and servos are available separately for those who want to use their own electronics.
The Mechanics
The robot is made exclusively from brushed, or black anodized aluminum servo brackets from our Servo Erector Set. It also includes an electronics carrier made from ultra-tough laser-cut Lexan.
The Servos
We are providing the walker with Hitec HS-422 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. We recommend using the 6.0 Volt Ni-MH 1600mAh Battery Pack (BAT-03) and the Universal Smart Charger (USC-01).
Controlling the Biped
The robot can be controlled in many ways. The combo kit for PC uses our SSC-32 and the Visual Sequencer to control the robots motion. It's a tethered configuration but can be made wireless with any commercial wireless serial device. We have example projects for the Visual Sequencer to get the robot going right away. We will offer a combo kit for Basic Atom as soon as we have programming available. We are working on wireless play station game controller code for remote control as well.
Important!
To keep costs down we are not providing printed Assembly Guides. They are provided online, so you will need to print them when you order the kits. By providing the Assembly Guides online we can provide more detailed and up to date information than the old hardcopy method allowed.
