Abstract

A method for designing and fabricating a robot utilizes 3D modeling tools and techniques. The method begins with creating a digital three-dimensional model of the robot. A 3D mechanical structure for the robot is designed based on the digital model. Aesthetic (typically external) and mechanical (typically internal) components based on the digital model and mechanical design are fabricated utilizing rapid prototyping machines and techniques. Other components are obtained or fabricated according to the 3D model and mechanical structure as needed. The aesthetic and mechanical components are then assembled into a completed robot.
