The Arm has a total of 6 axes:

• Axis 1 - Located at the base of the robot and helps it turn from left to right.
• Axis 2 - Allows the robot's lower arm to move up and down.
• Axis 3 - Allows a robot's upper arm to move forwards and backwards.
• Axis 4 - Allows a robot's upper arm to rotate in a circular motion.
• Axis 5 - Raises and lowers the wrist of the robot arm.
• Axis 6 - Allows the wrist of the robot arm to rotate freely in a circular motion.

These six axes are controlled by the two servomotors supplied.
