Looking part Tanystropheus, part Gungan and sporting a wicked pair of drive-units on a pivoting boom, this bot is Done!
The head is made of a license plate and the eyes are made of ping-pong balls lit by red LEDs. There are parts from several appliances, including a dehumidifier, computer-monitor, power-drills and various building materials.
The design is far from any boat or sub, having more in common with a compact, mobile buoy. It would be difficult to have less consideration for hydrodynamics, aside from raising up from the water when under-way.
