Servo Trims
Each of the joints on your
MechRC robot has been tuned
by our robot engineers at the
factory to deliver optimum
performance of the system
out of the box. However, after
extensive use or modification,
you may find it necessary
to adjust the trims (zero
positions) of the robot's
joints. To find out more about
this process, please refer to

What is a servo?
A servo is a precision electro-
mechanical feedback system
consisting of a motor, gearbox
and controller. A signal is
sent to the controller telling
it what position to drive
the output shaf t to. The
position of the output shaft
is continuously fed back to
the controller which ensures
that the specified position
is maintained, even if a
reasonable external force is
applied.
