In the past few months, we have had the chance to cover a bunch of cool underwater robots and drones. The Druiser is a tiny underwater drone with a HD camera module that lets you view all the action from a first-person point of view. It can be moved in all directions and has a control range of 10 meters.
The Druiser runs for 30 minutes on battery. It works with iOS, Android, and Windows devices. It has a lightweight polycarbonate construction. The vehicle is capable of diving to a depth of 10 meters.[where to get it]
