Meet the sideways scooting robot crab developed by engineers. Engineers developed the world’s tiniest remote-controlled walking robot, mimicking a mini crab that can shuffle sideways without any wire, hydraulics, electricity, or other standard mechanical components. The tiny critter is controlled using lasers.
The unique robot crab is one-fiftieth of an inch wide. The robot can bend, twist, turn around and even jump. The robots are made from an elastic “memory-foam” alloy that gets transformed into its 3D shape. The tiny robot crab is small enough to crawl sideways through the eye of a needle.
To make the crab walk sideways, the laser is beamed from one side of the body to the other, creating a wave through the body as it flattens and springs back into shape. The wave of motion causes the crab to move in the direction of the laser.
