Today, most robots get around by using wheels and legs. However, this robot uses a pair of rods that rotate and this causes the robot to tumble around. What I mean by "tumble" is that flips itself over and over again and that's how it gains its mobility. This robot is called Aquapod and was designed at the University of Minnesota's Center for Distributed Robotics. Aquapod uses a pair of carbon fiber rods that are attached to servo motors that are programmed to rotate continuously. The robot is also waterproof, no wonder its called Aquapod, and it also is capable of controlling its buoyancy. An when its not tumbling in the water its usually tumbling around the beach. You can see this robot in action in the video below. Thanks for reading and please comment below!
