Abstract
Existing tele-operated construction machineries are by far less efficient than directly operated ones. In fact, principal factor of inefficiency of the systems have not yet clearly determined. The authors developed a prototype tele-operation platform to examine tele-operation factors such as image presentation method, sound, vibration and time lag. In this paper, preliminary operability evaluation experiments using the platform are performed from image presentation aspect. However, the results were affected by fusion of three factors (image presentation, responsiveness of the operation subject, and skill of the operator) and difficult to separate into individual operability factor. In order to solve this problems, the responsiveness of the operation subject was improved. In addition, an operating method to exclude operator's skill was devised. The improved platform is tested by comparing 3D and 2D image presentation methods. The results demonstrated characteristics of 3D image properly.
