碩士 === 健行科技大學 === 機械工程系碩士班 === 105 === The advantages of twisted string actuator (TSA) owns light weight, low inertia, high efficiency, low cost and simple mechanism. Due to multiple advantages on TSA, the design of using such actuators are mostly on robotic manipulators, but these features is also suitable for material handling. Thus, the main goal of this thesis is concentrated on deign of the one dimension moving platform based on TSA to meet low cost and simple structure demand request. The driving unit is adapting servo motor with Arduino control board. Moreover, the film potentiometer is using as the position sensor to measure moving platform displacement owing to TSA actuation. The software package LabView2014 is introduced to build the control environment. However, the performance for TSA is influence by the string material properties, hence, this research select six different string to verify their functioning. Consequently, the new measurement model is proposed while modify the positioning equation. Experimental results confirm that such design is reliable and possesses low implementation cost.
