This is a 3D printed robotic arm. The intent was to design something “easy” and cheap to built with a good visual impact also. Test video: , . I spent time to look around the web at some examples available that could be a good starting from, and between all I found interesting the phenoptix MeArm V4 project ( especially for the simplicity and low cost of parts involved. So I kept only the kinematics geometry and redesign all parts including the gripper”
