Overview
Tech specs
Power
There is an on-board voltage regulator for higher voltages that protect the Braccio shield. NOTE: The protection doesn’t work for the Arduino Yun if you put the bridge between Vin and 5V on the Arm Robot Shield V1 (greater version of are called Braccio shield and has a power switch on the top of the shield)

FAQs
How many axis does the Braccio robot arm have?
The braccio has a total of 6 axis:
Axis 1 – It is located at the base of a robot, and helps it to rotate from left to right.
Axis 2 – It helps the lower arm of a robot to move in an up and down motion.
Axis 3 – It allows the upper arm of a robot to move forward and backward.
Axis 4 – This axis is known as wrist roll, and it rotates the upper arm of a robot in a circular movement.
Axis 5 – It permits the wrist of the robot’s arm to raise and lower.
Axis 6 – It allows the wrist of the robot’s arm to rotate freely in a circular motion.
All the above six axes are controlled with the help of servo motors.
