Abstract
A system, apparatus, and method are provided herein for haptic-based force balance for anti-sway control of a payload. A haptic feedback system for crane operation is provided including: a controller; a first haptic device including a first haptic device tip; a second haptic device including a second haptic device tip; and a structural member connecting the first haptic device and the second haptic device, where the controller is configured to correlate the first haptic device tip to a first reference point on a payload and to correlate the second haptic device tip to a second reference point on the payload, and where anti-sway control of the payload is effected by movement of the structural member by an operator.
Claims20
A haptic feedback system for crane operation comprising:
- a controller;
- a first haptic device comprising a first haptic device tip;
- a second haptic device comprising a second haptic device tip;
- and
- a structural member connecting the first haptic device and the second haptic device;
- wherein the controller is configured to correlate the first haptic device tip to a first reference point on a payload and to correlate the second haptic device tip to a second reference point on the payload, and wherein anti-sway control of the payload is effected by movement of the structural member by an operator.
A method for haptic feedback for crane operation comprising:
- receiving an indication of a first reference point of a payload;
- receiving an indication of a second reference point of the payload;
- causing movement of the payload at the first reference point based on input from a first haptic device;
- causing movement of the payload at the second reference point based on input from a second haptic device;
- providing haptic feedback to the first haptic device based on movement of the payload at the first reference point;
- and
- providing haptic feedback to the second haptic device based on movement of the payload at the second reference point.
A controller for haptic feedback for crane operation, the controller configured to:
- receive an indication of a first reference point of a payload;
- receive an indication of a second reference point of the payload;
- cause movement of the payload at the first reference point based on input from a first haptic device;
- cause movement of the payload at the second reference point based on input from a second haptic device;
- provide haptic feedback to the first haptic device based on movement of the payload at the first reference point;
- and
- provide haptic feedback to the second haptic device based on movement of the payload at the second reference point.
