Reinforcement Method by Densification of Inner Three-Dimensional Structure for Automatic Robot Designing

Abstract

Demands for robots are growing rapidly recently. However, such demands are wide-ranging, and each demand contains subtle differences. Hence, a rapid and easy robot design method is needed for dealing with a wide variety of demands. A robot design method that fulfills the robot’s inside with a three-dimensional (3D) diamond crystal structure-shaped structure was proposed previously. It is suitable for 3D printing and makes robot designing simple and easy. This proposed method achieved fast and easy robot design, but the structure inside the robot might become weak depending on the appearance of the robot, especially in a tight and thin shape. The method to detect and reinforce such weak structure is proposed in this paper for dealing with this problem using a Cohesive Blocking technique. The effectiveness of the proposed method is evaluated through the experiments of two types of robot appearance models.
