This is the Picotaur: a micro legged robot that can turn, push loads and climb mini stairs. Researchers in the Department of Mechanical Engineering at Carnegie Mellon University are behind this clever design. This robot has legs that are driven by multiple actuators. It has multiple gait patterns and can hop to overcome obstacles.
As the researchers explain, this 7.9mm robot was
“3D-printed using two-photon polymerization.” You can find out more here.
