Abstract

Development in manufacturing, automation, space and underwater exploration has shown vast number of robots being used where most of the existing robots are of coordinated control of a single arm only. Increasing demand for robots application, especially in manufacturing has opened a new challenge; dual arm robot cooperation. This challenge is to develop robots which can carry out greater task which could either be heavy in load or complex in working. The main objectives for this project are to study on the available techniques of cooperative control, to design a program based on the chosen technique, to integrate the program in the system of two existing robot arms handling one common load and to ensure precise tracking of a desired formation and simplicity in its design. The methods being used in this project are performing literature review, selection of cooperative control technique where three cooperative control techniques namely Master/Slave control, Centralized and Decentralized control are compared and implemented to the existing robots, as well as conducting experiment on the real system. Results from the experiment are analyzed and improvised to prove that cooperative control technique could be used for this study. Results from this study are in form of programming of the control system, ladder diagram showing inputs and outputs of the system utilized and calculation of error of relative coordinate of the two robots after experiment execution. In conclusion, master/slave technique has been selected to be most suitable for this study based on its accuracy and simplicity of its design. The objectives for this project have been achieved where no error above lmm recorded which indicates accuracy and number of lines of programming are 21 lines for Master and 16 lines for Slave robot thus, proving its simplicity. However, improvement on the method used could be further studied to minimize number of lines, using other method or extension of this project where rotational motion could be studied.
