Product Details


Been wondering what to try next with your Arduino Board? Introducing the TinkerKit Braccio. This fully operational robotic arm is designed for desktop use and comes in kit form, so you can assemble it to your own requirements, and easily adapt it once made. A Braccio service shield is included in the kit but you’ll need your own Arduino Board. Then the fun really starts. Pick up and move objects, mount a camera and track your movements during a video call, or attach a solar panel and track the movement of the sun. The uses are endless!


We recommend that you plug in the board using the jack connection and use the 5V power supply that comes with it, making sure it’s regulated and provides 4000 mA.

There’s a built-in voltage regulator that safeguards the Braccio shield from higher voltages. Please note: if you connect the bridge between Vin and 5V on the Arm Robot Shield V1 the protection won’t work for the Arduino Yun.
