Abstract

From the start of the third industrial revolution, manufacturer has started to incorporate robotic arm to help them increase productivity, output consistency, the overall quality of end product and also bringing their manufacturing cost lower. Robotic arm is expected to resume their role in the next industrial revolution as well. Worldwide, the application of industrial robots has accelerated significantly in recent years and this is reflected by the increasing demand for robotics in Malaysia's manufacturing industry. With more industries expected to use robotic arm, more skilled workers are needed in order to maintain and operate the robot. Our nation has targeted to produce a large number of skilled workers in the robotic field through TVET initiative. TVET curriculum prepares students for a career that requires specific skill-set in electrical and electronics, computer systems, automation and robotics, and manufacturing technology. Current industrial robots for education purposes are expensive and yet the mechanisms are too simple thus not representing the actual robots being used in the industry. This is where this project comes in. Through this project, a 6 DOF robotic arm are being design and fabricated. The overall size of this robot arm is 0.8m height and width of 0.35m which can fit on a standard table. Even though the size of this robot is small, this robot retains the mechanical attribute of an industrial robotic arm. This project only focuses on the mechanical structure of the robot. Electronics and programming of the robot movement shall be done separately. The design of the robot has been done using SolidWorks. Through this software, the structure has been analysed thoroughly in order to ensure this robot are able to handle the intended load of 1 kg. Through the analysis, the maximum stress, maximum displacement, and maximum deformation are identified by input of 5 different payload. The robot has been fabricated using FDM technology for fast development time dan other conventional manufacturing for metal part. Finally, the robot will be 6 DOF which suitable for TVET training and analyse the capability to perform at 1 KG of payload by using finite element analysis.
