Arduino Braccio Robotic Arm is the newest kit from ALSRobot.Because it is designed for versatility, the Braccio can also support various objects on the end of the arm.
For example, you can use Braccio:

  • With your camera to follow a subject,
  • By mounting your telephone or your tablet to follow you when you’re at a video conference,
  • With a solar panel to follow the sun.

The TinkerKit Braccio is sold as a kit and requires assembly before use.

After assembly, you can adjust the alignment of all the motors by running the sketch called “testBraccio90” in the Braccio examples.The sketch will position the Braccio in the upright position shown below. If it isn’t in this position, you will need to realign the servos.
