Robotic Arm Kit


OnPoynt is proud to introduce a great new line of ground robot kits from the Drone Ranger®. Though our partnership with Sun Founder, we are offering the Robotic Arm Kit 4-Axis for Arduino.

This is one of the latest additions to the Drone Ranger® line of education kits.

Like all OnPoynt education kits, this one comes with everything you need to build and operate it.


  1. The Rollarm is a 4-axis movement kit customized for robot hobbyists to learn to control the mechanical arm, with detailed user manual, code and introduction videos.
  2. 2 controlling manners: manually (by handle) or by computer (LabVIEW).
  3. Able to memorize about 100 movements made.
  4. Four servos compose and control the four joints, and grippers have double layers with pointed end and jagged edges – to grab objects firmly.
  5. Powered by two 18650 batteries.

The Rollarm Kit for Arduino is designed for mass hobbyists to learn robot arm control. With the open source MCU Arduino UNO and a servo expansion board, the robot arm is easy to use and full of fun. You can control its four axes by the 4 potentiometers on the handle, as well as make them move on your computer. In addition, it can memorize the movements it's made and repeat again and again, making it a great tool for repeated tasks.
