This project reminds me of the Tony Stark’s robot arm assistant involved in his projects to save the world. The miniature robot arm for your desk has been developed by Andreas Hölldorfer and is inspired by industrial robots.
The real intention is to build an affordable robot arm, and the cheapest solution was to use a 3D printer. The result is an ABS plastic robot arm with a weight of 1Kg without the gripper and the base. By printing the arm, you can benefit from a custom design with a lot of space inside the arm.
The printable arm is engineered with 5 degrees of freedom while the forearm can reach 3 degrees of freedom. The arm is fixed on a rotary platform that can be moved on any flat surface.
The plastic arm was designed in two versions: blue and orange. The blue one uses stepper motors, while the orange version is equipped with DC motors. The implementation of stepper motors is not the best solution for a robotic arm. These actuators provide accurate movement to the detriment of torque-to-weight ratio.
The arm is equipped with a three-finger gripper and a design borrowed from a commercial version.
This printable robotic arm is cheap, can be programmed and customizable. If you want to build your printed robot arm assistant, check the instructions page.
