Attaching the Arm

Start 

We'll need to take off the second level of Robotics Series 3 to attach the robot arm.

Undo Robotics Series 3 

Undo the cables going to the I2C Servo Driver and the I2C Motor Driver. Press down on the orange buttons on the servo driver then remove the jumper. Unscrew all terminal blocks on the I2C motor driver and remove the wires.
