NXT Packbot:

Part 4

by James Isom

Welcome to the final installment of Packbot instructions. There’s not much left now, so let’s get right to it and wrap it up.

STEP 1:

Parts:

Connect wires to each of the three motors and run them around the friction pins to the front of the Packbot. The ultrasonic sensor wire can stay towards the back. Looking from this perspective, the right motor will be connected to Port C, the bottom left motor to Port B, and the top left motor to Port A. The ultrasonic sensor will eventually find its way to Sensor Port 1.
