GS-1 Gyro Servo

Click here to order the GS-1

The GS-1 has the features of a R/C hobby servo combined with gyro stabilization. The gyro helps to keep the servo pointed in the same direction even when the servo moves around. It can be very useful for camera mounts to keep the camera pointed in the same direction while the camera platform moves, such as in kite and balloon aerial photography.

Features:

  • Same size as standard size R/C servos
  • 165 degree motion based on standard PWM control
  • Ball bearing on output shaft
  • Nylon gears for smooth operation
  • 37 grams (1.3 oz) weight
  • MEMS gyro to compensate for servo movement
  • Microprocessor control
  • Automatic gyro drift cancellation
  • Slow slewing on power-up to desired position

FAQ

Does the GS-1 eliminate all movement of the camera?

The GS-1 cannot remove all rotational movement, but in many situations, such as remote aerial photography, it will remove most of the movement. This can greatly improve the ability to keep the camera pointed in the desired direction, but it will not make the camera completely motionless.


How much rotational motion can be compensated for?

There is no specific limit to the amount of motion that can be sensed and corrected, however, the servo is limited to a range of 180 degrees. If you were 10 degrees away from the end of the servo movement, for example, the gyro could only correct for 10 more degrees of movement in that direction before reaching the limit.


Can I use multiple GS-1's for controlling the tilt, roll and pan of a camera?

Tilt and roll generally work well. Pan does not work as well unless the camera is suspended from a fairly stable mount. A typical KAP suspension has too much flexibility to properly support a GS-1 used for pan.


Can I use the GS-1 where the servo is mounted 90 degrees to the rotation axis of the object being moved (e.g. worm gear or bevel gear drive)?

No, the GS-1's gyro will sense rotation in the wrong direction.


Can I modify the GS-1 for continuous rotation?

No, the GS-1 is not compatible with modifications for continuous rotation.


Can I use the GS-1 for flight stabilization of a model aircraft?

The GS-1 is not designed for controlling flight surfaces.


Can I use the GS-1 for camera stabilization in a model plane or helicopter?

It will work, but the GS-1's automatic gyro drift cancellation can get confused when the aircraft goes into a sustained bank, leaving the camera tilted for a few seconds afterwards before it recovers.
