Say hello to RoboSea’s Robo-Shark, the coolest – and toothiest – underwater drone on the market. This two metre bionic shark slinks through the water lets you explore the underwater world from a sharks-eye view. Weighing 75kg it’s pretty hefty, but it does have automatic obstacle avoidance and a multi-joint caudal find that reduces water noise. However, unlike a real shark, the Robo-Shark tops out at a speed of 10 knots and with a maximum depth of 300 metres. The battery will last you two hours and it can be fitted with nearly any camera or sensor rig.
