Abstract

Based on the statistic, stroke is one of the largest killers in Malaysia only after heart disease and cancer where an estimated 40,000 people in Malaysia suffer from this type of disease. Another statistic shows 12 to 53 new spinal injuries per million inhabitants in the developed countries per year. These injuries lead to disability of human body parts including paralyzed arm. In order to assist paralyzed arm sufferers, studies have been conducted to improvise the development of bionic arms. Based on the problem statement, previous studies on bionic arm had some limitation to users. Moreover, previous study has also shown that the design of bionic arms is lacking in engineering characteristic. The objectives of this project are to derive the mathematical model of bionic arm using kinematic analysis and formulate joint torque and to design and validate the bionic arm in term of structural strength and torque. This proposed motion study is to provide opportunity and benefit for the patient who are suffering from paralyzed arm. Next, the methodology of the project started with kinematic analysis and mathematical model of bionic arm and validation by Robotics Toolbox MATLAB Software. Then, the formulate joint torque of bionic arm by static forces in manipulator is analysed. After that, the bionic arm was designed and analyzed by SolidWorks simulation. Finally, Maximum torque was simulated by SolidWorks Motion. As the result, the joint angle configuration on kinematics calculation and MATLAB Simulation both have obtained[1,0,0],[−1,0,0], [0,−1,0] and [0.5,0.5,0]. Then, SolidWorks Simulation obtained factor of safety, where the value is 34 and 14 for whole part testing and 772, 155, 4, 1273, 15 and 8 for by part testing. After that, the calculated result of formulate torque is 19.14Nm, 19.14Nm, 11.05Nm, 4.458Nm and 4.458Nm. Meanwhile, the results of SolidWorks Motion are 66.75Nm, 66.31Nm, 37.71Nm, 0.04Nm and 5.22 for dynamic motion method and 66.94Nm, 66.27Nm, 37.78Nm, 0.04Nm, and 5.21Nm for static motion method. For the conclusion, the derived kinematic model for bionic arm has been validated by MATLAB Simulation. Then, all analyzed structure strength parts are safe. Finally, the type of motor could be determined based on resulted maximum torque.
