Design of Soft Outer Shells for Control of Large Spherical Robots

RA-L 2025

While soft-shelled spherical robots offer promising mobility and robustness for planetary exploration, large-scale, mission-capable robots present several design challenges. This paper presents the design, manufacturing, and performance evaluation of multiple soft outer shell iterations for RoboBall

Empirical Contact Models for Soft Spherical Robots in Drake

RA-L 2025

Accurate dynamic modeling of soft-shelled spherical robots is challenging due to coupled rigid–soft body interactions and pressure-dependent contact behavior. This letter presents a modeling strategy for an empirically tuned pendulum-driven inflatable spherical robot. The approach combines a rigid-b

Empirically Compensated Setpoint Tracking for Spherical Robots With Pressurized Soft-Shells

RA-L 2025

Replacing spherical robots' hard shells with soft, pressurized tires has the potential to improve their off-road practicality immensely. This change leverages spherical robots as a simple and rugged solution to problems currently addressed using wheeled or tracked vehicles. Though numerous prototype

RoboBall: An All-Terrain Spherical Robot with a Pressurized Shell

ICRA 2024poster

Spherical robots are a different type of mobility platform. A spherical robot is self-contained within its shell rather than relying on a chassis with wheels to navigate. In this shell, it is completely shielded from dust and the environment. This benefit of geometric simplicity has led to the spher…
