Video: Atmel & Arduino power this robotic hand

A high school student known as “Gabry25” has designed a wirelessly controlled robotic hand using an Atmel-based Arduino LilyPad and an Atmel-powered Arduino Uno.

As Julian Horsey of Geeky Gadgets reports, the wireless robotic hand faithfully reproduces the movements of an accompanying glove worn on another hand.

Aside from the above-mentioned Arduino boards, key project components include:

  • Shield to connect the Xbee module
  • Robot_Shield
  • 5 Flex sensors
  • 5 resistors: 47 KΩ
  • Battery pack with 3×1.5 V batteries
  • LilyPad FTDI adapter (optional)
  • A steel structure for the palm of the hand and wood for the fingers
  • 5 servomotors
  • Fishing wires
  • 9 V Battery

“To connect the servomotors I used the Robot_Shield from FuturaElettronica, which has also a switching regulator to power the entire circuit, but you can use any shield made for that,” Gabry25 explained in a recent Instructables post.
