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. Please note: Arduino board not included.
Power
It is recommended to power the board via the jack connection with a regulated 5 VDC @ 4000 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 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)
Includes
- 21x Plastic Parts
- 63x Screws
- 16x Flat Washer
- 7x Hexagon Nut
- 2x Springs
- 2x Servo Motors: 2x SR 311, 4x SR 431
- 1x Arduino compatible Shield
- 1x Power Supply 5V, 4A
- 1x Phillips Screwdriver
- 1x Spiral Cable Protection Wrap
Note: Does not Include Arduino Board. The Arduino Board will need to be purchased separately.
Braccio Shield: The maximum length and width of the Braccio Shield PCB are 2.7 and 2.1 inches respectively, with the power jack extending beyond the former dimension. Four screw holes allow the board to be attached to a surface or case. Note that the distance between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the other pins.

The TinkerKit braccio is open-source hardware! You can build your own board using the following file:
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.
