METHOD AND DEVICE FOR CONTROLLING WALKING ASSIST DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18103517 titled 'METHOD AND DEVICE FOR CONTROLLING WALKING ASSIST DEVICE

Simplified Explanation

The abstract describes a method and device for controlling a walking assist device. Here is a simplified explanation of the abstract:

• The method involves determining the gait state of a user wearing the walking assist device based on their walking pattern.
• A smoothed and time-delayed state variable is obtained from the determined gait state.
• A torque control variable is applied to the smoothed state variable to obtain a third state variable.
• The walking assist device determines the assist torque to be provided based on the obtained third state variable.

Potential Applications:

• Rehabilitation: The walking assist device can be used in rehabilitation settings to assist individuals with impaired mobility in regaining their walking abilities.
• Elderly Care: The device can be utilized in elderly care facilities to provide support and assistance to elderly individuals with walking difficulties.
• Sports Training: Athletes or individuals undergoing sports training can use the walking assist device to improve their gait and walking performance.

Problems Solved:

• Limited Mobility: The walking assist device addresses the problem of limited mobility by providing assistance and support to individuals with walking difficulties.
• Gait Abnormalities: The device helps correct gait abnormalities by analyzing the user's gait state and providing appropriate assist torque.
• Fall Prevention: By providing assistance and stability, the walking assist device helps prevent falls and injuries in individuals with impaired mobility.

Benefits:

• Improved Mobility: The walking assist device enhances the mobility of individuals with walking difficulties, allowing them to move more comfortably and independently.
• Personalized Assistance: The device analyzes the user's gait state and provides customized assist torque, ensuring optimal support tailored to the individual's needs.
• Enhanced Safety: By providing stability and assistance, the device reduces the risk of falls and injuries, promoting a safer walking experience.

Original Abstract Submitted

A method and device for controlling a walking assist device is disclosed. The method includes determining a first state variable for a gait state of a user wearing the walking assist device based on a gait of the user, obtaining a second state variable which is smoothed and time-delayed from the first state variable, obtaining a third state variable by applying a torque control variable to the second state variable, and determining an assist torque to be provided by the walking assist device based on the obtained third state variable.
