Figure 1: The completed Trackbot Mk V.
At the front of the Trackbot is a user-controllable robotic arm. The arm is driven by a DFRobot Romeo microcontroller that takes input from the RC receiver. Internally the claw uses Hitec servos.
Power for the the whole robot comes from a large 3-cell lithium polymer battery. A step-down converter is used to bring the battery voltage (11.1 V) down to the voltage required for the electronic components of the robot. The step-down converter used features a large display that indicates the voltage set by the converter.
We thank kwoeltje for posting the details of his build and are pleased he chose to use our RoboClaw motor controller. For the full detailed build guide and more photos please follow this link to Instructables.
