Landing-sleep and drifting-sleep experiments of the underwater glider for long-term observation

For long-term monitoring, the authors are developing a prototype underwater vehicle that can sleep on the seafloor or sleep while drifting underwater. Using these functions, it can carry out long-term monitoring of ocean environments while remaining in a designated area. Recent landing-sleep and drifting-sleep experiments yielded good results. Results of these experiments reported herein demonstrate that the landing motion showed good coincidence with the simulation result.
