This 4WD is the little brother of the 6WD Wild Thumper: It takes almost no time to go from un-boxing to rolling chassis, but it's also ready to be expanded on and makes great base for an Advanced Robot.
The chassis has wicked spiked 120mm diameter wheels and an anodized aluminium chassis made from 2mm thick plate.
The Kit now includes 2x Quadrature Magnetic Wheel Encoders that can be optionally mounted. These can be used to perform accurate speed control, essential in advanced Robotics applications.Please note: the WildTumper Arduino DC Motor Controller is
The chassis has 4mm diameter holes punched every 10mm to allow easy mounting of PCBs, servos etc. All nuts, bolts and screws are stainless steel. Brass fittings and suspension springs are nickel plated.
The Wild Thumper Arduino DC Motor Controller is built by Dagu specifically for their robot platforms. It essentially combines an Arduino development board with a dual H-bridge motor driver all bolted down to an aluminum heatsink. The heart of the board is an ATMega168 AVR microcontroller which comes loaded with the Arduino bootloader and some simple control code. Code can be easily accessed and changed in the Arduino IDE using the on-board FTDI chip and mini-USB connector. All of the headers on board are accompanied by ground and voltage lines to allow for easy servo connection.
The controller allows for on board charging of SLA, NiCd or NiMh battery packs and has a dedicated barrel jack socket for DC input. A 5 Amp LDO voltage regulator handles the step-down from standard 7.2 or 7.4v RC battery packs. A set of screw terminals are provided for the battery connection as well as for connecting external devices (5 volt regulated out).
