Prove II SG is a 4 channel 75Mhz radio controlled ROV designed for operation in an unstructured outdoor environment. It's four 12 volt DC gearhead motors directly drive modified lawn mower wheels, making it slow, but nearly unstopable. It currently features 3 video cameras, including a high resolution color camera with a variable zoom/focus lens, as well as a pan/tilt navagation camera and a fixed rear view camera. Video and audio is transmitted over a 2.4 Ghz link. Camera switching, and other controls are performed by a DTMF push button control system using 430Mhz FRS radios. This vehicle has completed several successful runs outdoors, including a recent live webcast that allowed people from as far away as India to watch live transmitted video over the internet. While Probe II SG is fully functional, I consider it a work in progress, as it itself is a testbed for more complex additional systems.
