These two aquabots were built for display at the California State Fair. They are being displayed indoors in large glass tubes. Since artificial lighting is being used, they are tweaked to charge and pop as quickly as possible. The red one is a climber and the purple bot is a diver. They were both designed to be easily opened and repaired if needed. Both bots have a threaded cap incorporated with the solar array. The diver also has a second cap at the bottom to allow for replacing the motor. The motors have a brass tube glued and sealed to the shaft bearing that pushes through a rubber grommet on the bots body. This makes for a removable, yet water tight seal. Both bots also have a secondary FLED circuit that operates off of the two calculator solar cells via a pockmark arrangement. One Farad super caps are used as buffers on the FLEDs so that they operate for roughly an hour after the lights go out. The bodies are made entirely of plastic to eliminate corrosion. The props are homemade from thin brass sheeting and bolted to a plastic inner shaft.
