Enhancing the durability of robotic arm using composite materials and additive manufacturing in harsh environmental conditions

Abstract

Despite the harsh environmental conditions, such as strong winds, radiation exposure and frequent forest fires, pose serious challenges for the reliable operation of robotic systems. Despite growing interest in robotics for disaster relief and hazardous operations, the durability of additively manufactured components under such stresses remains insufficiently explored. This study investigates the use of composite materials and additive manufacturing techniques to improve the performance of robotic manipulators in harsh conditions. A modular rover equipped with a robotic arm made entirely of composite elements was developed and tested. The research focused on evaluating the structural reliability of PETG plastic and carbon fiber in terms of thermal exposure, static load, and radiation resistance. The study also presented a gesture-controlled interface for remote control and produced a functional prototype. The results of the study provide new insights into material selection and design strategies for sustainable robotic systems, contributing to the development of sustainable robotics in harsh environmental conditions.
