# Description

About the MH2 Walking Robot The MH2 hexapod robot is designed around a simple mechanical leg design with all metal brackets. This leg design minimizes the number of parts required to make a two DOF (degree of freedom) leg and allows this robot to be steered like a tank. Forward, reverse and in place turning is supported. The robot uses standard sized Hitec servos for the legs. The combo kit includes everything you need to make a functional robot except batteries and optional PS2 controller. The Mechanics The body of the robot is made from ultra-tough laser-cut PVC structural components while the legs are made from high-quality aluminum Servo Erector Set brackets. The MH2 includes 12 servos; six HS-422 and 6x 645MG. The robot is able to adjust its height, walk forward and in reverse, as well as rotate clockwise and counter-clockwise, tit forward and backward, left and right and more. Controlling the Robot There are three control options for the MH2. The first combo kit, the MH2, comes with the SSC-32 and the Bot Board II + BASIC Atom Pro 28. This kit is programmed using Basic Micro Studio. The second kit, the MH2U, includes the SSC-32 and a BotBoarduino, and is intended to be programmed using the popular Arduino software. By offloading the servo pulse generation and sequence movement timing to the SSC-32, the microcontroller has plenty of power to do some really cool things. The sample code allows the robot to walk using the PS2 controller (sold separately). The third kit includes a full version of FlowBotics Studio and includes the SSC-32 as well as a serial to Bluetooth board and Bluetooth module which allows for remote control from the computer. This approach offloads the higher level calculations to the computer. FlowBotics Studio includes a demo project for the MH2 with pre-written walking algorithms. Powering Options The robot is compatible with the following batteries and chargers. Chargers > NiCad & Ni-MH Universal Smart Charger (USC-01) Batteries > 6.0 Volt Ni-MH 1600mAh Battery Pack (BAT-03) > 6.0 Volt Ni-MH 2800mAh Battery Pack (BAT-05) 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.
