Welcome to

mrxEE

mrxEE (MUREX Experimental Engineering) is MUREX Robotics's highly experimental research division. Calling upon our foundation of innovative, open-source electrical engineering (hence the origins of EE) designs, we push the absolute limits of modern day robotics. Beyond the MATE ROV Competition, our true goal is to change the world around us with groundbreaking innovation. The industry doesn't move us –– we move it. We achieve what no other team in the world is capable of. And we do it incessantly. Email: [email protected] ACHIEVEMENTS
