Squirtle

Squirtle is the LSTS Mini ROV integration of the BlueRobotics BlueROV2 platform. This system is another example of integration of COTS hardware into LSTS toolchain, enabling the control and command in our typical network. 

For the control part, previous integrations were used from UAV Ardupilot projects having now also support for manual control for the Ardusub subproject. Besides the original ROV configuration, this system also has an acoustic modem which can be used for communication and positioning with other nodes underwater. This ROV model is also suitable for expanding its capabilities and payload modularly.
