Robot 9 • The SpinnerBot
Final Step 11
The RCX snaps
onto the three-
quarter
length
pins on
the Inner
RCX Bracket
sub-assembly. The
position of the RCX is key
to a mobile robot, as it is
typically the most important factor
in the balance of the robot.
Final Step 12
Snap the Outer RCX Bracket sub-
assembly onto the end of the
chassis, securing the
RCX. The Outer
RCX Bracket and
RCX can be
readily removed.
Final Step 13
Flip the robot
over and add
the skid plate to
the underside of the
RCX. This plate provides a
reasonably low-friction
bearing for the SpinnerBot, since it is
almost perfectly balanced over the wheels.
