For the past 22 years, the MATE ROV competition has challenged students to expand their electrical, mechanical and programming skills by creating an ROV that can complete a variety of underwater mission tasks using a tethered ROV. In 2022, MATE introduced a new type of challenge. MATE Floats!, inspired and funded by GO-BGC as part of the OneArgo array, tasked teams to build an independent self-profiling float that was independent of the ROV, could move vertically on its own in the water column using its own onboard power source, and that could collect and transmit data back to a shore side station. Student team members of all ages tackled this mission with creativity and ingenuity, building on their technical skills and understanding of ocean technology in use today.
