Design And Manufacturing Of Low Cost Pneumatic Pick And Place Robot

Abstract The paper proposes a cheap and effective method for design and manufacturing of a three degree of freedom revolute jointed robotic arm. The design process begins by specifying top-level design criteria and passing down these criteria from the top level of the manipulators structure to all subsequent components. With this proposed approach the sequential design intents are captured organized and implemented based on the entire system objectives as opposed to the conventional design process which aims at individual components optimization. By considering the mechanical arms performance objectives the design starts with modelling the integration of all the individual links constituting the manipulator. During the design process modifications are made based on integrated information of kinematics dynamics and structural analysis of the desired robot configuration as a whole. An optimum assembly design is then achieved with workable sub designs of the manipulator components. As a result the proposed approach for manipulator design yields substantially less number of iterations automatic propagation of design changes and great saving of design efforts. Further with best machining process and cheapest material catering the strength and machining requirements suitable materials are selected to fulfil the objective
