What is "Active Stabilization"?
Everyone is familiar with the simple act of balancing a yardstick on the tip of
a finger. Attempts to balance the same yardstick on a table by standing it on
end, however, will likely end in failure. The human being in the loop clearly
adds the necessary ingredient to make the balancing trick work.
The human being adds the following three basic control system elements.
1. The first element is the motor supplying mechanical movements and forces.
2. The second is the sensor element which monitors movements of the thing being
3. The third element is the intelligence which processes all sensor data and
generates the required motor control commands.
Arm and hand movements perform the motor functions, eyes monitor the
yardstick position and movements, and the sensor data (yardstick position and
movement information) is received and processed by the brain (computer) which
then generates commands to move the motor (arm and hand) to maintain the
yardstick in balance.
