The world of robotics is constantly evolving, and researchers from Carnegie Mellon University (CMU) and UC Berkeley are pushing the boundaries by giving quadruped robots new capabilities. Inspired by the versatility of their biological counterparts, these researchers are teaching quadrupeds to use their front legs for tasks beyond just walking and running, such as climbing walls, pressing buttons, and kicking a soccer ball. This groundbreaking development in robot jobs is opening up new possibilities for hiring robot workers with advanced manipulation skills.

Currently, most quadruped robots use their legs solely for navigation, with some models like Boston Dynamics' Spot employing a robotic arm for manipulation tasks. However, the team at CMU and UC Berkeley has taken a different approach, teaching a Unitree Go1 quadruped to use its front legs for both locomotion and manipulation. Equipped with an Intel RealSense camera for perception, this robot worker can now perform a variety of object interactions in the real world, in addition to walking.

The researchers achieved this breakthrough by decoupling skill learning into two categories: locomotion and manipulation. By training the quadruped in simulation and transferring the skills to the real world using their proposed sim2real variant, they enabled the robot to simultaneously move for balance and manipulate objects with one leg. This innovative approach has the potential to revolutionize the way we hire robot workers for various tasks.

To create a robust long-term plan, the team taught the quadruped a behavior tree that encodes a high-level task hierarchy from a single expert demonstration. This allows the quadruped to move through the behavior tree and return to its last successful movement when it encounters problems with certain branches. For example, if the robot fails to climb a wall to press a button, it will return to its previous successful task, like approaching the wall, and start again.

The research team, consisting of Xuxin Cheng, Ashish Kumar, and Deepak Pathak, acknowledges that a limitation of their work is the decoupling of high-level decision-making and low-level command tracking. However, they believe that developing a full end-to-end solution is an exciting future direction for the field of robotics.

As the capabilities of quadruped robots continue to expand, so do the opportunities for hiring robot workers with advanced manipulation skills. By embracing these innovations, businesses can unlock new possibilities and transform the way they approach various tasks.
