本發明中,我們設計一超音波測距模組以及意圖判斷演算法,可實際應用在行動輔具機器人控制、低成本體感操作設備開發、醫療復健器材等產品。透過創新的機構設計,可偵測使用者髖關節角度變化,並搭配所開發之行走意圖判斷演算法有效辨識使用者的行走意圖,系統並以Kalman濾波器來預測其下一角度變化以增加系統效能。本設計之應用實例為實踐於一被動式機器人輔具,透過此系統預測使用者之行走意圖,並依此進行輔具控制,以達到輔助使用者行走、復健等目的。 In this invention, we propose a novel system with the ultrasonic ranging finder module designed to detect human hip angle change and human-intention detection algorithm developed to efficiently identify user’s walking intention. The invention can be applied for the active/passive walking helper, low-cost somatosensory device, medical rehabilitation equipment, etc. Via the system, the change of the user’s hip angle during movement can be measured and utilized to determine his/her walking intention. Moreover, the Kalman filter is used to predict the following walking intention to enhance system efficiency. The system is realized on the passive walking helper previously developed. Via the prediction of the user’s walking intention, the system contributes to the helper in its control, leading to the assistance of the user in walking and rehabilitation.
