Design and Control of Robot Arm for Inspection and Rescue Operations

摘要

This paper presents the kinematic and dynamic analysis of the robot arm for inspection and rescue operations. The inspection robot arm has Pitch–Pitch–Pitch–Yaw motion for an optimal and stable view of the camera installed at the end of the manipulator. The rescue operation robot arm has Yaw–Pitch–Pitch–Roll motion to handle heavy tools. Additionally, both robot arms are waterproof, as they use the triple-layer O-ring. Furthermore, the dynamic equation including the damping force due to the mechanical seal for waterproofness was derived by using the Newton–Euler method. A control system using the ARM processor was developed and introduced in this paper, and its performance was verified through experiments.
