Following the Fukushima tsunami incident, the government had initiated a program to develop a range of remote control unmanned machines such as hydraulic excavators which can access disaster areas for clean-up operations. In comparison with conventional construction machines, the tele-commanded robots have good dynamic characteristics and haptic force, aiming at accurate and reliable work. The power supply wire can be drawn around for a long time. Their image processing system can also be based on outside cameras in case of aerial fog and allows for different viewpoints in complex terrain.
