US 2026/0144697 A1 · ROBOTIC WALKER FOR GAIT AND POSTURAL STABILITY ASSISTANCE WITH A HIGH LEVEL OF AUTONOMY AND SAFETY

Abstract

A device may include a rigid frame having a left side and a right side. A device may include a caster wheel attached to a front portion of each of the left and right sides of the rigid frame. A device may include a motorized wheel assembly attached to a rear portion of each of the left and right sides of the rigid frame, each motorized wheel assembly comprising an electric motor with a driven output coupled to a mecanum wheel configured to provide omnidirectional movement. A device may include sensors for detecting rotational position and speed of the electric motors. A device may include one or more cameras oriented toward a user of the walker configured to monitor user posture, gait, and balance.

Dependent claims

A walker comprising:

one or more LiDAR sensors configured to perform range finding and obstacle detection;
and
an autonomous walker controller configured to:
generate a motion trajectory for electric motors based on a user's surroundings, body posture, and intended movement;
automatically guide the walker around obstacles with the motion trajectory, even if in conflict with the intended movement;
guide the walker into a more supportive position with the motion trajectory if the user is at imminent risk of a fall;
stop all movement if a use scenario becomes unsafe;
identify a fall by estimating a relative position of a user's center of mass;
and
generate a profile of a user's habitual movements and preferences to personalize the generated motion trajectory.
