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.
But the “LocoMan,” robot is unique because it can transition from its all-fours stance to a standing pose and use its two front legs to manipulate objects. The scientists outlined how the robot worked in a study posted March 27to the arXiv preprint server.

“In this paper, we present LocoMan, a novel approach that enhances the manipulation dexterity of quadrupedal robots through the integration of designed lightweight loco-manipulators, expanding their operational workspace and enabling precise control over complex 6D manipulation tasks,” the scientists said in the paper.
