在台灣身心障礙人數約有102萬人,國民平均每230位就有一位領有殘障手冊,並且每年人數都有增加的趨勢,且以壯年40歲到65歲退休人士年齡範圍成長趨勢最大。隨著文明的進步,科技輔具越來越受到人們的重視,但台灣現有的科技輔具,大多數從國外進口,不僅價格上也相當昂貴,輔具的大小尺寸,也較少考慮到國內民家的體型及使用者的需求。因此本研究聆聽身心障礙者需求並採納其意見,再與職能治療師討論相關關鍵問題後,進而開發出符合國內使用的生活輔具,希望可以改善身心障礙者在日常生活上的不便與障礙。
在此本研究中,希望可以開發是以多功能輔具開發為主,目前開發完成的輔具有翻書機與餵食機,在開發過程中,為了減少開發時間與成本,我們採用可程式樂高積木(LEGO MINDSTORMS NXT)模組做為開發平台,主要是利用樂高積木的創意組合性,實現輔具平台的快速開發與組裝,並透過各種感測器的整合,設計出各種控制開關及回饋裝置,實現客製化自動化的科技輔具。除了使用可程式樂高積木模組外,也運用相關微電腦控制技術,將原本昂貴的樂高NXT主機取代,開發出低成本且增加系統彈性的可攜式生活輔具控制平台。
以本研究團隊完成的翻書機為例來說,我們針對不同書頁材質做實驗,其基本成功率達83.3%,在使用的過程中皆不需透過事前訓練就可使用;而餵食機則針對不同黏稠度食物做實驗,其乾性食物基本成功率為92%,而較為潮濕的食物,因積木材料強度較低與馬達轉矩受線的關係,成功率只達64%,如此的多功能輔具系統主要可用來改善身心障礙者在就養、就學以及娛樂上的需求,也可為身心障礙者提供全方位的輔具服務,改善其生活品質。
There are about 102 million disabled persons in Taiwan, meaning that 1 in 230 people is disabled. In fact, the trend has been constantly increasing annually. Therefore, more and more people are putting their attention on assistive technology. However, most of the existing assistive devices are imported from other countries and the price is quite expensive. In addition, little consideration was given to the control of these devices to fit the needs of the users. For this reason, the research took the views of persons with disabilities, and occupational therapists to discuss crucial issues related to developing assistive devices. And to solve the inconvenience for the people with physical and mental disabilities face in their daily life.
In our research, we developed the multi-functional assistive devices, including the page turner and the feeder. In order to reduce the cost and development time, the programmable LEGO (LEGO MINDSTORMS NXT) was adopted as the development platform. The goal of designing a creative customized assistive device was achieved with the combination of LEGO and various sensors, and control switches, to achieve quick platform assembly. In addition, a new circuit board is being developed to replace the current expensive programmable LEGO ARM 7 NXT. The new platform will reduce cost and improve flexibility in producing portable assistive devices of life.
The research team implemented the page turner, and testing it on books with different materials and number of pages. The accuracy was about 83.3%. Everyone can operate the page turner without training in advance. In addition, the feeding machine implemented was tested on food with different moisture content and dry food. It showed the a accuracy of 92%. For damp food, due to the materials used and the strength of machine structure, it has a lower accuracy of only 64%. However, the related multi-functional assistive devices we implemented can help the disabled in long-term care, education and entertainment needs. These different functions of assistive devices can also be used for handicapped aids to provide a full range of services to improve their quality of life.
