Bad weather can often interfere with the monitoring work conducted by unmanned surface vehicles at sea, which is why scientists at Universiti Malaysia Perlis have come up with the Sea-Eye -- a battery-powered unmanned surface vehicle designed in such a way that it works even if it's toppled upside-down by waves or winds.
The Sea-Eye has two sets of propellers located at the top and bottom. When it flips over, the top propellers automatically switch off and the bottom ones switch on, allowing it to continue its work. The device can be manually remote controlled or operated autonomously using GPS.
The Sea-Eye is also equipped with on-board solar panels, allowing it to generate power to recharge its batteries.
