Analýza možností užití kompozitů v konstrukci robotů

Abstract

The main advantage of composite usage in the construction of robots lies in the weight reduction and the decrease of moment of inertia of their structure while its stiffness remains unchanged or even increases. In the introduction of this diploma thesis, the analysis of the state of the art in the field of composite materials is performed. From the specification of possible usage of composites in the individual mechanisms of robots, the scope of the diploma thesis is chosen to focus on the application of carbon fibre laminates in the construction of the upper arm of an industrial robot. Then, two alternatives for the structural design of the upper arm are proposed. Based on their confrontation, more superior alternative is selected. This alternative is structurally designed, and essential calculations, a 3D model of the upper arm in Pro/ENGINEER package and the assembly drawing of the upper arm are given. The concept of the arm includes the design of laminate components and their attachments to metal end pieces. A load-bearing laminate profile is compared with profiles made of conventional materials.
