. “We started doing this custom build work in 2019 on a project for the University of Indiana, funded by the US Navy, to develop a hybrid autonomous ROV/AUV that could self-navigate and avoid in-water objects on its own,” says Director and Founder Matthew Mooney. “It had a number of sonar systems onboard, and depth sensing cameras, and its own processing system that we designed and worked in collaboration with the team at Indiana University to create. It’s still being used for research purposes to this day in the US.”The company is currently making a ROV for an oil and gas
