摘要: | 本篇論文提出了一個建置於主動式助行器機器人平台,基於步態分析的行走平衡復健系統。隨著社會人口高齡化現象益趨明顯,醫療照護人員不足的問題將變得更加嚴峻。因此,我們需要藉由步行輔助機器人協助照護人員來舒緩人手不足的困擾。對於很多年長者來說,行動不便於日常生活中造成非常大的困擾,因此,如何改善老人的行動力一直是個重要的議題,特別是對於巴金森氏症患者而言,他們在行走過程中會經常性的發生異常步態。為了改善巴金森氏症患者的行動力,我們必須觀察並分析他們的行走步態,並且針對異常步態做出對應的改善措施。因此在本篇論文中,我們將以患有巴金森氏症的使用者作為探討對象,建置一個以步態分析為基礎的行走平衡復健系統,在此系統中,不同於傳統上的輔助行走機器人,我們加入深度資訊感測器於使用者下肢前方作步態辨識。並配合改變輔助行走機器人的移動速率與發出配合使用者正常步態的頻率提示音等過程協助使用者脫離異常步態。我們也實際於安養中心請巴金森氏症長者測試此系統,結果顯示當巴金森氏症長者使用此系統輔助行走時,相較於不使用此系統時,呈現較穩定的步態。 This thesis proposes a gait analysis based walking stabilization system on an active robotic walker for Parkinson’s Disease patients. Due to population aging, the demand of caregivers will be very insufficient in the future. Therefore, we need a robotic walker to help the caregivers. The improvement of elderly mobility has also been an important issue, especially for the Parkinson’s Disease patients. Most of the Parkinson’s Disease patients are suffer from losing balance and abnormal walking gaits, so we take Parkinson’s Disease patients as our user of the system. To improve the Parkinson’s Disease patient’s gait performance, we must comprehend the meaning of human gaits. Thus, we develop a gait analysis based walking stabilization system. Instead of using laser range finder or body-mounted sensors to estimate the walking motion, we use only one RGB-D sensor mounted on the robotic walker to capture the user’s lower limbs from the frontal view. After we captured the depth information of the lower part of body from the sensor, we automatically construct the skeleton of the lower limbs. By the kinematic model of the lower limbs, we can establish the user’s walking gait features such as average walking step length, velocity, width and joint angle. By adjusting walker's velocity and prompting user with auditory cues, the walker will help user to stabilize their gaits when they suffering from abnormal gaits. We invite Parkinson’s Disease patients to test our system in senior care unit, the experiment results show that when Parkinson’s Disease patients use this system, they have relatively stable gait than without using this system. |
