Mechatronic Experiments Course Design - A Myoelectric Controlled Partical-Hand Prosthesis Project

Mechatronic Experiments Course Design: A Myoelectric Controlled Partial-Hand Prosthesis Project Ton-Tai Pan, Ping-Lin Fan, Huihua Kenny Chiang, Member, IEEE, Rong-Seng Chang, and Joe-Air Jiang, Member, IEEE Abstract—This paper describes a proposed laboratory project involving the design of a myoelectric-controlled partial-hand prosthesis to reinforce mechatronic education. The proposal focuses mainly on extract electromyogram (EMG) signals generated during contraction of the biceps. The EMG signals are first amplified and filtered by a laboratory-designed electronic circuit and then reprocessed using a microcontroller to drive the servomotor so that the designed prosthesis can be properly controlled. The project introduces students to component-level and system-level design and. | 348 IEEE TRANSACTIONS ON EDUCATION VOL. 47 NO. 3 AUGUST 2004 Mechatronic Experiments Course Design A Myoelectric Controlled Partial-Hand Prosthesis Project Ton-Tai Pan Ping-Lin Fan Huihua Kenny Chiang Member IEEE Rong-Seng Chang and Joe-Air Jiang Member IEEE Abstract This paper describes a proposed laboratory project involving the design of a myoelectric-controlled partial-hand prosthesis to reinforce mechatronic education. The proposal focuses mainly on extract electromyogram EMG signals generated during contraction of the biceps. The EMG signals are first amplified and filtered by a laboratory-designed electronic circuit and then reprocessed using a microcontroller to drive the servomotor so that the designed prosthesis can be properly controlled. The project introduces students to component-level and system-level design and exposes them to the integration of a microcontroller electronic circuits sensors and prosthesis mechanisms. Moreover since the project results in a working prosthesis student enthusiasm for mechatronic education increases and they see its relevance to the field in applied engineering. Implementation of the laboratory project within the curriculum has been demonstrated to be highly motivational and educational and has even helped to attract more students to study mechatronic applications. Index Terms Electromyogram EMG laboratory curriculum mechatronic education microcontroller. I. Introduction ALL undergraduate students who major in Electrical Engineering EE and Bio-Industrial Mechatronics Engineering BIME at Kuang-Wu Institute of Technology KWIT and National Taiwan University NTU respectively both in Taipei Taiwan are required to take one mechatronics course. The course syllabus originally focused on programmable logic controller-based control topics. Recently the single-chip microcontroller has been one of the most widely used alternatives in industrial and consumer applications 1 2 . Growing demand and the need for novel teaching materials
