A development of tele-controller for hydraulic excavator

Because of the hydraulic excavator operates in the hazardous working circumstance, operator of excavator exposed in harmful environment. Therefore, Tele-Operation for hydraulic excavator has been investigated to protect from the hazardous working environment. A development of Tele-Controller for hydraulic excavator was purposed in this paper. For the purposed Tele-Controller will be divided into two parts. The first part is a retrofit of hydraulic system by the addition of proportional valves from the existing valves into a hydraulic excavator. The second part consists of the embedded system, which serves as a control unit and processing the movement of hydraulic excavator. In addition, this section also contains notebook computer, joystick, IP cameras, and wireless equipment. For command from joystick and display from IP cameras are designed using the Microsoft Visual Studio and C# program. The performance of Tele-Controller was evaluated through the field test by experts and operators of hydraulic excavator system, which the results were satisfactory.
