Tinkerkit Braccio Robotic Arm for Arduino Arduino

DESCRIPTION

Unlock the unlimited possibilities of robotics with BRACCIO!

You can assemble your BRACCIO in a multitude of ways. Because it is designed for versatility, the BRACCIO can also support various objects on the end of the arm. The included BRACCIO shield allows you to hook up the servos directly to your Arduino board.

The BRACCIO can be used to:

• Hold your camera so you can take remote images, capture a moving timelapse or even track a subject
• Hold your phone/tablet or other forms of displays
• Create a solar panel system that moves with the sun

FEATURES

Power

It is recommended to power the board via the jack connection with a regulated 5 VDC @ 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 doesn’t work for the Arduino Yun if you put the bridge between Vin and 5V on the Arm Robot Shield V1 (the greater version is called Braccio shield and has a power switch on the top of the shield)

Fully assembled Braccio Kit:

• Weight: 792 g
• Maximum operating distance range: 80 cm
• Maximum Height: 52 cm
• Base Width: 14 cm
• Gripper Width: 90 mm
• Cable length: 40 cm
• Load Capacity: 
• Maximum weight at 32 cm operating distance: 150 g
• Maximum weight at the minimal Braccio configuration: 400g

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.
