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).
