The Technological Advancements of Robotic Arms in the Field of Unmanned Aircraft

Abstract

As technological progress is made in electronic manufacturing, navigation, and control, the utilization of unmanned aerial vehicles (UAVs) has grown more widespread. This research paper conducts a comprehensive investigation into the technological advancements of robotic arms within the unmanned aerial vehicle (UAV) domain. By performing a comparative assessment across five distinct aspects - propulsion methods, structural configuration, control mechanisms, materials, and longevity, and usage scenarios - it delves into the strengths and weaknesses of both conventional and novel technologies, along with their prospective development paths. The research indicates that piezoelectric drive technology is capable of realizing lightweight robotic arms. For instance, there is a micro-aircraft whose total weight is merely 259 milligrams. Bionic flexible structures notably boost the adaptability to intricate environments. As an example, octopus tentacles can grasp an object with a diameter of 200 mm. The utilization of AI autonomous control and self-mending materials tackles the problems of poor precision in conventional remote control and restricted material longevity, respectively. Despite the fact that emerging technologies continue to face difficulties in terms of load-bearing capacity, cost, and the ability to adapt to extreme environments, their potential in new-age scenarios like healthcare services, forest surveillance, and deep-sea investigations has been verified. In the future, research efforts ought to combine multi-sensory perception, materials with variable stiffness, and standardized testing frameworks. This integration will propel the advancement of UAV robotic arms towards achieving greater intelligence and seamless integration across multiple scenarios.
