  • Mujin develops and sells "intelligent robot controllers" with the goal of building a common platform for industrial robots. Conventional robots are suitable for automating repetitive work, but traditionally they've been hard to install in environments where products and surroundings change. Most robots have complex settings that are hard to change for each use case. Mujin's tech solves this problem using technology called motion planning. It allows them to provide solutions that replace heavy but simple work done by humans with automation by robots. The technology is used primarily for logistics and manufacturing applications.
