Abstract
A force-feedback assembly includes a first shaft with a shaft end. The first shaft is movable between a shaft first position and a shaft second position. The force-feedback assembly also includes a compliant element arranged to exert a return force on the first shaft and bias the first shaft toward the shaft first position. The force-feedback assembly additionally includes a ramp in sliding engagement with the shaft end. The force-feedback assembly further includes an operator input device operatively coupled to the ramp. The operator input device has a device first position and a device second position. Moving the operator input device from the device first position to the device second position slides the ramp relative to the shaft end and moves the first shaft from the shaft first position to the shaft second position.
