    The Snapper Robot Arm is a perfect entry level kit for getting started with Arduino and robotics. This Arduino Robot Arm is aimed at those looking for robot kits for hobby and education. The Snapper is based on the open source Arduino controller and the extremely modular RobotGeek family of parts, sensors, and components. The robot arm can be easily modified and upgraded for many different types of projects.

    The robot arm kit comes with a control panel allowing user control right out of the box using provided sample code. The manual control panel is used to easily position the arm into poses for capture. After capturing all of your poses for your sequences you are ready to enter them into your program for playback. No other Arduino Robot Arm kit gives users everything they need to program arm movement sequences all in one kit. The robot arm can be controlled through the manual control panel, programmed code, direct PC link control, or through any type of custom built control panel using various sensors and anaolg input.

    Four RobotGeek high-torque servos allow this robotic arm to easily pick up 50 gram objects with an impressive reach of 29cm from shoulder to gripper.

    The Geekduino (the RobotGeek Arduino compatible microcontroller board) controls each Snapper Arm. Atop each Geekduino is a RobotGeek Sensor Shield, making it clean and easy to plug in the robot arm's servos and sensors into the Geekduino. This setup offers 6 PWM outputs, 8 digital I/O, 6 analog I/Os, 1 I2C port, and 1 serial data port. This shield makes it a snap to change and add sensors, output modules, and more! And because the base of the Snapper Arm is covered in a standard RobotGeek 1x1 cm grid, it's easy to mount RobotGeek modules and boards directly to the arm. You will need to sand your gripper for smooth operation, more details available in the assembly guide.

    Even the Snapper Arm mount itself is built in the 1x1 cm grid pattern - this means that the arm can easily be removed and mounted onto other RobotGeek plates, like the Large Workbench and the RobotGeek Geekbot.
