This project involves in the design and development of a Cable Actuation Unit that is compact, accurate and low cost. Therefore, it will enable us to facilitate the experimental testing of the Cable Driven Parallel Manipulator (CDPM). The scope for this project will be firstly setting up the design objectives. The design objectives are having a 5 cm/s velocity for the cable extension, assuming a 250 N force acting on each cable and cable able to make an extension of 15 cm in length. Secondly, Conceptual design of the Cable Actuation Unit is done through the use of morphological chart. The morphological chart helps to generate complete variations of solutions from a few designs functions that are essential to the cable actuation unit. . Thirdly, the finalized design is been selected through the use of a matrix evaluation table. The finalized design is refined and worked on and a detailed design is produced in the process. Lastly, cost estimation is done for the Cable Actuation Unit. The detail parts list for the cable actuation unit is divided into two categories. The two categories are custom made parts and purchase parts. The custom made parts are design and drafted to be made in the machining workshop. The purchase parts are source from the local supplier Misumi South East Asia Pte Ltd and Servo Dynamics Corporation. The cost for building the cable actuation unit is estimated based on the price list available on the catalog and present market rate.
