This disclosure describes a low-profile, high-load, and hands-free ball-balancing omnidirectional rolling system with multiple human-robot interfaces for modular and adaptive design configurations and input control interfaces. The disclosed platform uses a self-balancing ball-based robot to allow for a safe, compact, high-load, self-balancing and intuitive mobility device for a person with lower-limb disability. Advanced driving assistance such as obstacle avoidance and semi-autonomous navigation between predefined locations is also disclosed.

Low-profile and high-load ball-balancing rolling system

A crutch includes a pole, a cuff, a handle, a forearm support member, and a second forearm support member. The cuff and the handle are attached to the pole. The forearm support member, comprising an actuator, is disposed between the cuff and the handle and is moveable between a constricted position and a non-constricted position. The second forearm support member is disposed within the forearm support member. The energy generating device is configured to move the forearm support member between the constricted position and the non-constricted position.
