Some interesting features of Sentry are:
- Built by engineers at Woods Hole Oceanographic Institution (WHOI).
- The robot is designed to dive as deep as 5,000 metres and can dive up to 20 hours.
- The robot is powered by more than 1,000 lithium-ion batteries, similar to those used in laptop computers, to withstand extreme pressures underwater.
- During the first cruise last year, the robot surveyed about 53 square kilometres of seafloor including high-resolution mapping of the seafloor.
- The robot can be pre-programmed for operation.
