Proteus, named after the Greek sea-god or god of rivers and oceanic bodies, is the first completely self-developed robotics system of Tethys Robotics. The applications are particularly research and development of underwater technology. For this reason, the system is highly modular and resemblances a more classical approach of a UUV design. Furthermore, the system software is based on a updated version of SCUBO 2.0. A major innovation is that Proteus communicates via a thin fibre optic cable with the control station on shore.
The system is powered by on board rechargeable batteries which allow an operation of at least 4 hours. Although the thruster configuration is not as symmetric as the one of SCUBO 2.0, the system is still omnidirectional and has a similar controller. To navigate the UUV, the robot is equipped with a stereo camera, depth sensor, IMU, SBL and sonar.
The separate tube enclosure for the electronics and batteries ensure the modularity of the system and a depth rate of 300 m which is enough to explore all Swiss lakes. The sensors can be easily exchanged and any other type of sensors can be added without big changes in the design to improve the depth rating for up to 600 m.
