1. The document describes the design of a multipurpose land and underwater rover controlled by a Raspberry Pi.
2. The rover is intended to perform inspection, monitoring, and data collection tasks both on land and underwater in a safe, affordable and low-maintenance way.
3. It carries sensors to measure environmental data like temperature, pressure, depth and transmit live video to provide information without risking human divers. Potential applications include inspecting bridges, ships, offshore infrastructure and studying marine life.
