Scientists have developed a quadrupedal robot that can use its two front legs to pick up and handle objects while walking on its hind ones.
Quadrupedal robots usually take the form of robot dogs, including Boston Dynamics' Spot. They can walk over challenging terrain at speed and usually have low centers of gravity. Most object-manipulating quadrupeds have two additional arms that can pick up and carry objects — meaning they have six "limbs" in total.
