Scientists have developed a quadrupedal robot that can use its two front legs to pick up and manipulate objects while walking on its hind legs.
Quadrupedal robots usually take the form of robotic dogs, including Boston Dynamics’ Spot. They can walk over challenging terrain at speed and generally have low centers of gravity. Most object-handling quadrupeds have two extra arms that can carry objects – meaning they have six „limbs” in total.
But the „Logoman” robot is unique because it can switch from all four positions to a standing pose and use its two front legs to manipulate objects. The scientists outlined how the robot works in a study published on March 27want arXiv Preprint server.

„In this paper, we present a novel approach called LocoMan that improves the manipulation skills of quadruped robots by integrating designed lightweight loco-manipulators, expanding their functional workspace, and enabling precise control over complex 6D manipulation tasks,” the scientists said.
