<p>Aside from obvious things like dropping or spilling liquids on your
RCX, you can also cause physical damage by setting up a gear train
with enough torque to permanently damage one or more of its components
if it becomes jammed. The weakest link in such cases is usually the
axle with the lowest rotational velocity, but it's also possible to
ruin gear teeth, shear connector pins, bend plates, etc. Often the
damage results from something getting jammed after you turn the robot
on, either because the design is bad or because something gets caught
in the works. There's no simple answer to this, but often it's useful
to include deliberate failsafe elements in your design -- like beams
that pull apart only if gears become jammed. </p>
