Rollbot 2: Agile Locomotion by a Single-Actuator Spherical Robot
Overview
Rollbot 2 improves upon the original Rollbot by maintaining a single-actuator design while introducing a redesigned mass distribution for more direct movement. It uses onboard inertial and ultra-wideband sensing to autonomously navigate toward beacons and follow waypoints, achieving a 468-meter indoor route at 0.87 m/s and completing a 4.8-meter 'N' benchmark in 10.8 seconds with a mean deviation of 7 cm.
