Robotic cane devices
First Claim
1. A robotic cane comprising:
- a grip handle;
a cane body extending from the grip handle at a first end of the cane body;
a motorized wheel assembly comprising at least one wheel coupled to a second end of the cane body;
a proximity detector, wherein the proximity detector provides a proximity signal corresponding to a position of a user with respect to the robotic cane; and
a controller module, wherein the controller module is programmed to;
receive the proximity signal from the proximity detector;
calculate a distance of the robotic cane from the user based at least in part on the proximity signal; and
provide a drive signal to the motorized wheel assembly such that the robotic cane follows the user without user contact at a predetermined distance, such that the grip handle is within a reach of the user.

Abstract
A robotic cane may include a grip handle, a cane body extending from the grip handle at a first end, a motorized omni-directional wheel coupled to a second end of the cane body, a balance control sensor, and a controller module. The balance control sensor provides a balance signal corresponding to an orientation of the robotic cane. The controller module may receive the balance signal from the balance control sensor and calculate a balancing velocity of the motorized omni-directional wheel based at least in part on the balance signal and an inverted pendulum control algorithm. The controller module may further provide a drive signal to the motorized omni-directional wheel in accordance with the calculated balancing velocity. The calculated balancing velocity is a speed and direction of the motorized omni-directional wheel to retain the robotic cane in an substantially upright position.
