SmartLapse and the elektraDRIVE motor system are a non-encoded motor system. There is no feedback between the motors and controller, so the controller has no way of knowing if the motor is missing its trajectory, and it does not know if anything has changed, since the move was recorded. For example a change in the camera payload or incline of the track. With SmartLapse, the Oracle is recording the motor voltage and then playing back the exact same voltage, assuming everything is exactly the same as when recorded.
For example, if when the camera is manually put back into the "Start" or "Home" position, if it is not exactly where it was for the recording, the play back will be off as well. As long as no variables have changed, the accuracy should be around 97-98%.
Our new motion control system, Second Shooter/Second Shooter Plus and CineDrive use digital encoded motors, so there is constant communication between the motors, providing position data, to the controller to ensure the accuracy of the movement.
