Proactive failure prevention by human-machine interface in remote-controlled demolition robots

Abstract

The objective of the paper is to design an advanced Humane Machine Interface implemented in remote-controlled robot for demolition works. The paper includes the use of Design Thinking methodology in the conceptual design process for determined user-machine problems. The experimental testing with high-speed camera and vibrometer were performed to obtain the input data for numerical analysis. Then the finite element method simulations were carried out to provide the assumptions for HMI solution. Finally, a novel arm-mounted HMI status/caution/warning lighting was designed and executed in the robot controller. The system notifies the operator about the load capacity and warns the operator about leading the arm in resonant frequency, which is a main cause of the reported robot’s arm fatigue failure.
