In this paper, we will describe our attempt for a tele-operated humanoid robot to drive a backhoe. It will be possible for a humanoid robot to drive an industrial vehicle instead of a human operator. If a humanoid robot can be operated by a human operator from a remote site, it enables to use a general type of vehicle safely in a dangerous field. We introduced a backhoe as the target vehicle to show the possibility of driving a vehicle in a sitting posture. The robot sits down with balancing on a cockpit of the backhoe and manipulates control levers for driving. We developed a portable remote control device and remote control methods to operate the humanoid robot. For the evaluation, it is tested to sit down and manipulate the levers on the driving cockpit of the real backhoe. To compare it with a human's work, the efficiency is close to practical use.

We have been developing new abilities of humanoid robots to realize proxy driving of a lift truck. Construction machines such as a lift truck play an important role in many tasks, but sometimes the environments are too hazardous for human operators. If a tele-operated humanoid robot can drive a construction machine, it can work at a dangerous place. This humanoid robot operator has two advantages over an automated construction machine. It is much easier to carry the robot to a disaster site than moving the special construction machine. Besides, the robot may be less expensive than developing the special automated machine whose required number is relatively small. We have been developing new abilities of the tele-operated humanoid robot HRP-1 to realize the application. The paper describes results of investigations and experiments for proxy driving of a lift truck by HRP-1.
