Method and apparatus for improving the operation of a remote viewing device by changing the calibration settings of its articulation servos
First Claim
1. A method for improving the operation of a remote viewing device, the method comprising:
- removing at least a portion of slack from at least one control cable attached to a servo motor, the removing at least a portion of slack including at least changing a distance between the servo motor and a flexible tube termination block until a specified tension is encountered in the at least one control cable;
fixing the servo motor where the specified tension is encountered;
determining a first servo control signal value corresponding to no angular deflection in a viewing head of the remote viewing device;
determining a second servo control signal value corresponding to a first angular deflection in the viewing head; and
increasing the viewing head'"'"'s range of motion by recalibrating the operation of the remote viewing device based on at least the first servo control value and the second servo control signal value.

Abstract
The present invention features a remote viewing device that is capable of improving its operation by removing slack in its control cables and/or by increasing the range of motion of its viewing head. In one embodiment, the method for improving the operation involves removing at least a portion of the slack in at least one control cable attached to a servo motor. The removal of at least a portion of the slack includes changing the position of a servo motor relative to a flexible tube termination block until a specified tension is encountered in at least one of the control cables. The method further includes determining first and second servo control signal values corresponding to no angular deflection and a specified deflection in a viewing head.
