Do you have what it takes to take manual control of a vertical profiling float and pilot it mission success? Hit the target depth and hold within the required zone for each of four phases, while carefully adjusting for a neutral buoyancy point that changes with each new dive. Inspired by the Float mission task in the MATE ROV underwater robotics competition (www.materovcompetition.org). Say "hi!" to the PVIT ROV team at the 2026 MATE ROV World Championships or on Instagram @PVITROV
