7. Gripperbot > Assembling the Gripperbot’s Electronics

Assembling the Gripperbot’s Electronics

The system concept for the Gripperbot is relatively simple. There are a variety of motors. The base has two of them, the right and left tank treads. The turret has four of them, the spinner, the “elbow,” the “wrist,” and the gripper. The bracers translate motion and button presses into speeds for specific motors. All of the XBee nodes broadcast to all other XBee nodes. The base and turret receive all messages, and only act on the ones that are intended for motors that they control. The turret uses the Bricktronics Motor Controller, which comes pre-programmed with a set of commands for motors 1 through 5, one for each of its ports. This project only uses four motors on the Motor Controller, which are numbered motors 1 through 4, so the two tread motors on the base’s Arduino are numbered 6 and 7.
