The Mechanics and Control of Leaning to Lift Heavy Objects with a Dynamically Stable Mobile Robot

ICRA 2019poster

A control algorithm is developed to enable dynamically stable spherical-wheel robots (ballbots) with arms to detect a heavy object of unknown mass, navigate to it, lift it, transport it, and place it in a desired location semi-autonomously. Previous work has successfully demonstrated two-wheeled dyn…

Initial results for a ballbot driven with a spherical induction motor

ICRA 2016

We give a system overview and initial experimental results for SIMbot (spherical induction motor based ballbot), a human-sized dynamically stable mobile robot with only two active moving parts. SIMbot is a qualitatively new kind of robot with the potential to drastically reduce mechanical complexity
