Effect of Presenting Dynamic Characteristic Information of Teleoperated Hydraulic Excavators on Work Efficiency when Switching to a Different Class

We propose a method by which to assist an operator in switching an internal model by visually presenting information about the dynamic characteristics of the destination in accordance with changes in dynamic characteristics when switching teleoperated hydraulic excavators. Experimental results show that when switching without presentation, the operation time significantly increased by 8:8%, compared with that observed when not switching. However, when using the proposed method, there was no increase in work time owing to switching. Therefore, the proposed method makes it possible to immediately switch the internal model of the operator.
