Humanoid legged locomotion is versatile, but typically used for reaching nearby targets. Employing a personal transporter (PT) designed for humans, such as a Segway, offers an alternative for humanoids navigating the real world, enabling them to switch from walking to wheeled locomotion for covering larger distances, similar to humans. In this work, we develop control strategies that allow humanoids to operate PTs while maintaining balance. This control task differs from walking control but is equally challenging and demands quick reactions. Our controller is based on a stack of tasks quadratic program (QP) formulation, which accounts for contacts, stability, and bimanual manipulation constraints. We present experimental results of a REEM-C humanoid operating a Segway x2 SE.Authors: Vidyasagar Rajendran, William Thibault, Francisco Javier Andrade Chavez, and Katja MombaurInstitution: University of Waterloo
