Motorized walker
First Claim
Patent Images
1. A motorized walker comprising:
- a wheeled frame;
one or more electric motors;
a manual online controller;
at least one proximity sensor sensing a plurality of regions around the motorized walker, including sensing a wall adjacent to the motorized walker; and
an automated control system;
wherein the automated control system further comprises;
a non-volatile memory that stores data and a plurality of executable program modules;
a processor coupled to the non-volatile memory;
a first executable program module being a procession module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker moves in a forward direction;
a second executable program module being a reverse module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker moves in a reverse direction;
a third executable program module being a right turn module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker turns toward the right;
a fourth executable program module being a left turn module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker turns toward the left;
a fifth executable program module being a stop module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to stop the one or more electric motors of the motorized walker;
a sixth executable program module being a speed control module that is stored within the non-volatile memory and that when executed by the processor determines the appropriate speed at which the motorized walker moves;
a seventh executable program module being an object avoidance module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker slows and turns to avoid frontal collision; and
an eighth executable program module being a tracking module that is stored within the non-volatile memory and that when executed by the processor supplies control signals to at least one of the one or more electric motors of the motorized walker such that the motorized walker travels parallel to and maintains a fixed distance from the adjacent wall.

Abstract
A motorized walker is provided that can enable users to walk without being slowed by the walker and without needing to exert themselves to push the walker forward. The motorized walker provides additional haptic speed cues to inform the user'"'"'s posture and locomotion control to prevent falling.
