生醫訊號驅動之仿生手臂
指導老師:游仁德   組長:譚向堯   組員:林郁芊
現今生活下,如有缺肢的人確會成為生活上的一大不方便,這些人也許不是先天遺傳或疾病所造成,而是後天的意外所導致,那人工義肢對這些人來說是使其能重拾往日便利的一項利器。此專題的研究就是以此部分人的問題為基礎,藉由人的生理訊號當作輸入,控制人造手臂的運動,而做出簡單的抓握動作,讓有缺肢問題的人能夠在生活上不再那麼不方便。由於生理訊號非常微弱,必須先以一連串的放大電路處理過後才能作為輸入使用,然而因為生理訊號非常小甚至伴隨著雜訊,因此過濾掉雜訊也是重要的課題,透過Arduino開發板分辨是否超過或低於我們所設定之閥值來分辨動作,再使用馬達拉動線材使人工手達到抓握的動作。
Nowadays, it is really inconvenient for those who have the problem of missing limb. Maybe they aren’t born to be disable, just caused by some unpredictable accidents. Then bionic arms can be that tools to make their life as convenient as before. The main purpose of this research is based on those problems, using the biomedical signals for inputs, and control the bionic arm in response. Thus they can do some simple move with that arm. Because the biomedical signals are very small, so before be used to be output it’s necessary to have the signals go through a series of amplifier process. However biomedical signals are always accompanied with noise, so it’s important to filter them out. By using Arduino to distinguish the signals are higher or lower than the threshold we set, and then use motors and strings to enable the bionic arm.
我們決定將壓電陶瓷晶片和鞋子做結合。
