Top: time history of the vehicle’s position. Bottom: time history of the vehicle’s orientation 8.6 Conclusions Interaction control in the underwater environment isavery challenge task. Currently, only theoretical results exist that extended the industrial-based approaches to the UVMSs. Obviously, while these approaches worked in simulation their real effectiveness can be proven only with an exhaustive experimental analysis. Simulations, nevertheless, gave useful information about the need to equip the system with high bandwidth and low noise sensors in order to interact with stiff environment. φ
