Tinkerkit Braccio robot

The TinkerKit Braccio is a fully operational robotic arm, controlled via Arduino. It can be assembled in several ways for multiple tasks such as moving objects. You can also attach a camera or solar panel. There are so many ways in which the Braccio can extend the reach of your devices.

Power

It is recommended to power the board via the jack connection with a regulated 5 VDC (at) 5000 mA power supply provided in the box.

There is an on-board voltage regulator for higher voltages that protect the Braccio shield. NOTE: The protection doesnt 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)
