Abstract: A simulation rider transporting apparatus includes a seat having means for constraining an attitude of a rider mounted on a first base and having a second base positioned under the first base. Elevation means for elevating the first base include two cranks which are arranged opposite to each other between the first and the second base. Each of the cranks has crank arms with each crank arm having one end coupled to the second base. A crank rod is provided for coupling the other end of each crank arm to the first base. Drive means are provided for changing a relative angle between the two crank arms to a predetermined value and for holding the changed relative angle.

Abstract: A VR motion producing apparatus includes a dynamic object to be controlled, a motion base having a finite stroke and motion model converting means for converting in a real time a motion model of a dynamic object to be controlled which is moved within a virtual reality space constituted by computer graphics into another motion model of the motion base having a finite stroke. The motion model converting means includes means for converting coordinate data of the motion model of a dynamic object to be controlled into coordinate data of the motion model of the motion base.

Abstract: A system for controlling an industrial robot, which is simplified in operation and capable of direct-teaching safely all the time. The system is provided with means (131 and 132) for monitoring a magnitude of an external force applied to the forward end of a hand during direct teaching, so that the motion of the robot can be forcibly restricted when the external force reaches a predetermined value of thereabove. Furthermore, when the system is operated to be set in a direct teach mode, a process (136) of correcting the offset of a force sensor is performed automatically.
