Robotic Arm Can with adjustable positions

myminifactory

This is a robotic arm made with 250mL cans and 3D printed joints and base. Each joint can be adjusted freely in any desired position; simply disengage the gears, rotate the arm, and engage again. The cans fit snugly inside each joint, which features holes for screw placement to prevent aluminum movement. A metal clip can also be placed at the axle of the joints to secure it in place, eliminating the risk of falling apart. As seen in the photos, the starting position of the arm can be set to any angle desired. This basic robotic arm has numerous purposes, but the attachment included with this model is a 'can' holder at the end. This model also serves as an excellent teaching tool for kids to learn how real robotic arms work in industry settings, although they typically use motors at each joint to control positions. Unfortunately, I don't have access to a 3D printer to print the joints and assemble the robotic arm; however, I would love to have this robotic arm on my desk, where I could attach various end-effectors for different purposes.
