Design and Development of a Gearless Spherical Robot
Abstract

The development of a gearless spherical robot addresses the limitations of traditional wheeled and legged robots in scenarios involving collisions with the ground or other objects while throwing or manuevering. This innovation introduces a dual-pendulum mechanism that enhances stability, maneuverability, and robustness while eliminating the vulnerabilities associated with gears. The robot's unique design allows it to be throwable, with a protective hull that shields internal components from environmental hazards. Featuring a compact form, precise control, and dynamic stability achieved through an optimized ratio of moments of inertia, the robot supports autonomous, semi-autonomous, and remote-controlled operations. It is designed for diverse applications, including security, planetary exploration, surveillance, environmental monitoring, and search and rescue, ensuring reliable performance in challenging terrains.
