This Robotic wheel can change its radius to create larger wheels to climb over things, and shrink back to a smaller size to squeeze under obstacles
The diameter of the wheels grows and shrinks automatically to enable the robot to either be strong or speedy.
The origami wheel can enable the robot to be both speedy and strong because it expands and shrinks in size automatically.
And, it is possible to control the shape of the wheel using only a few actuators.
The scientists think their innovation could one day be used for interplanetary rovers as the wheel can be folded up and 'inflate' itself."
