  • Remote handling apparatus for load object and auxiliary apparatus thereof
    Patent number: 9260278
    Abstract: A remote handling apparatus includes a joystick device, a load lifting device and a counterforce controller. The joystick device includes a counterforce generator that generates operation counterforce via a stick that accepts manual operation. The counterforce controller includes a pulsed counterforce controller and/or a deviation counterforce controller. The pulsed counterforce controller calculates a time rate of change of a dynamic load value of the load object, and outputs a counterforce command signal indicating a counterforce command value for generating pulsed counterforce. The deviation counterforce controller calculates a deviation amount of a dynamic load value from a static load value, and outputs a counterforce command signal indicating a counterforce command value for generating a counterforce. Embodiments may be implemented as an auxiliary apparatus, which is attached to an existing remote handling apparatus.
