Benefits of technology
This patent is for a system and method that allows a user to wear a device on their feet to increase their walking speed. The device has sensors that collect data on the user's gait, and that data is used by a processor to create movement commands for the device. This results in the user being able to walk faster with the device than without it. The control system is adaptable to each user, so no learning or extra effort is required.
Problems solved by technology
While bikes or scooters can be used, they are bulky and require skill and a minimum level of fitness to operate.
Powered systems, such as moving walkways, suffer from a lack of mobility.
Other mobility solutions suffer the same drawbacks or lack the ability to adapt to a particular user.

Embodiment Construction
[0009]As shown in FIG. 1, a mobility device 100, according to one embodiment, comprises a plurality of wheels 101, with at least one of the wheels 101 connected to an electric motor 102. Further shown in FIG. 1 is an onboard controller 111 and an optional remote controller 112. During typical use, a user will wear two mobility devices 100, one on each foot. The mobility device 100 enables a pedestrian to walk faster than a normal walking pace by adding torque to the wheels 101 of the mobility device 100 worn on the foot in contact with the ground. In this manner, the user experiences an effect similar to that of walking on a moving walkway. More specifically, the control system 110 of the present invention enables a user to maintain a normal walking motion by adapting the control of the motor 102 to the movements of the user. As will be discussed in greater detail, the speed at which the wheels 101 spin, through a torque applied by the motor 102, is controlled in part by an analysis...

A system for control of a mobility device comprising a controller for analyzing data from at least one sensor on the mobility device, wherein the data is used to determine the gait of user. The gait data is then used to provide motion command to an electric motor on the mobility device.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit under 35 U.S.C. § 119 of U.S. Provisional Application No. 62 / 530,177, filed Jul. 8, 2017, which is incorporated herein by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]The invention relates to a mobility device. More specifically, the invention relates to a control system and method of controlling a mobility device having an electric motor that is worn on the feet of a user to provide mobility assistance.[0004]Commuters and other travelers often have to walk the final leg of their trip, regardless of whether they traveled by car, bus, train, or other means. Depending on the distance, the time needed to complete this final leg of the journey can comprise a significant amount of the total duration of the trip. While bikes or scooters can be used, they are bulky and require skill and a minimum level of fitness to operate. Powered systems, su...
