Robot tarantula can tackle tricky terrain

A nightmare-inducing robot tarantula has been built using a 3D printer. The all-terrain machine, which weighs less than 5 kilograms (11lbs), can climb tricky surfaces like rocks and stairs with ease. It runs using 18 different motors that help it move smoothly over uneven surfaces. The motors give the robot exceptional flexibility and even appear to make it dance in a video of the strange machine. A hexapod robot is a mechanical vehicle that walks on six legs.
