    Abstract

    This paper describes an approach force-feedback of excavator which is considered for tele-operation using a novel designed haptic device in virtual environment. This study has two main themes, the newly designed haptic device and force-feedback algorithm in virtual environment for excavator. The device can be controlled by human arm joint. Using the device, motion of boom, arm and bucket is controlled by operator's elbow, wrist and metacarpophalangeal (MCP) joint. The motion of a novel haptic device is very similar to excavator. So, it is very intuitive and operator can control the device easily, even if they use it for the first time. It is a marked contrast between commercial haptics and this device. And then, 3D virtual environment is modeled for the force-feedback experiment using OpenGL program and 3D graphical simulations are extensively performed. The haptic offer force-feedback to operator exerted on each link of excavator during the performing various operation with DC motors. In this case, the force, which is forced by DC motor for feedback, is different as purpose of excavator and type of working. In order to increase the efficiency of operation and the protection of equipment, it is necessary to detect the reaction forces.
