movemaster.js - Reviving a 40 year old robot and integrating it into the JavaScript ecosystem

movemaster.js

7 / 2025

The Mitsubishi Movemaster EX was a simple robot sold in the 80s for basic handling tasks. While it was not very advanced, it was still interesting to bring this one back to life. The original API is not available anymore, but it is still possible to communicate with the robot via Serial. I developed a server and frontend that communicates directly with the robot.

The robot can now be controlled in a very simple manner. It uses a modern, async synthax that allows to build robot applications fast – without having to worry about the ancient programming language that is usually needed.

The application was tested on a original robot connected to a Raspberry Pi at the State Academy of Art and Design in Stuttgart.
