Abstract

By the year 2030, it is estimated that 800 million workers all over the world could be replaced by robots and this is evident of a robotic revolution happening in healthcare worldwide. This study aims to model and design a humanoid robot with additive manufacturing process. Computer aided design (CAD) models of the selected concepts were developed in Fusion360 and imported into SolidWorks to optimise and improve the design. The first stage of the design focused on the development of the main body and wheelbase, while the second phase focused on the arms and manipulators. To meet the project requirement of a payload of 500 g we selected a tough and low density material with appropriate servo motor with a torque of 9.4 kg/cm at each joint. The parts of the robot were produced by additive manufacturing process with an extrusion technique called fused deposition modelling (FDM) where a continuous filament of thermoplastic material, Polylactic acid (PLA) was fed from a coil via a moving heated extruder head and gradually deposit on the work. Overall, the robot proved that the proposed design is able to achieve the design requirements while mimicking basic human movements.
