This ROV is controlled by a Basic Stamp2 and is fully controlled via StampPlot. This allows for a GUI interface and feedback from the sensors while you are exploring the vast depths of the local lakes.

Initially I had hoped to have an un-tethered ROV. I tried to transmit data using Bluetooth from a laptop to the ROV underwater but as soon as it went under the surface all communication stopped. I also tried data communication using two radio transceivers operating at 438Mhz but got the same result.
