Meet Snapper Arduino Arm: a robotic arm for those of you just getting started with Arduino and robotics. This open source kit has an extremely modular design, so you can modify and upgrade it. The robot arm kit comes with a control panel that lets you control the arm right out of the box. Sample code is provided as well.
The robot has high-torque servos, so it can pick up 50 gram objects. The Gripper has adjustable angle finger tips. It is controlled using a Geekduino (Arduino compatible microcontroller board). More information is available here.
