ROBOTIS is behind some of the coolest educational robots we have tested. It is now selling a Koch v1.1 Robotic Arm kit, which is a low cost robotic arm based on Alexander Koch’s design. It uses Dynamixel XL430 and XL330 servos. It is compatible with LeRobot framework for machine learning. This video shows how this robot can be used to build a leader/follower system.

This kit ships with servos and other required components to build a robot. You are going to need a 3D printer to complete this project. According to ROBOTIS, the Koch Arm may become available as a complete bundle in the future.
