PURPOSE:To make it possible to control even when the visual range is intercepted by converting distance information obtained by a distance sensor to torque by a signal processing device and a torque adjusting device and transmitting to an operator through a control lever as a response. CONSTITUTION:When a moving machine 4 is running at a distance X1 from a wall, the distance X1 is obtained by processing the signal of a distance sensor 5 by a signal processing device 6. Torque T1 is obtained by inputting the distance information to a torque adjusting device 7. Torque T1 in the direction to return the control lever 1 to upright is generated in the axis 1a of the control lever 1 by an electric motor 8. As resistance of the control lever 1 changes with the distance from an obstacle, an operator can know the distance from the obstacle by response of the control lever 1 without vision. |
