BALL DAMS (2040+ ONLY)
Robo-Pong 2040+ comes with a pair of Ball Dams. They
serve three functions: (1) they keep balls inside the Center
Trough when the robot is folded up, (2) they keep balls
from entering the Center Trough when you want to remove
the robot body, and (3) they serve as a ball gauge for deter-
mining if a ball is the proper size and whether it should be
used in the robot.
The Ball Dams, when used for functions 1 or 2, fit into
two retaining slots at the top of the Center Trough. When
not in use, the Ball Dams fit into their storage slots on the
side of the Center Trough (see Figure 11).
To use the Ball Dams when preparing the robot for
storage or transport, remove the Ball Dams from their stor-
age slots by pulling slightly up on the trays to reveal the
storage slots (see Figure 13). Then push all the balls into the
Center Trough and insert the Ball Dams into their retaining
slots (see Figure 12). To use the Ball Dams for function #2,
push the balls up into one of the Ball Return Trays and
quickly insert the Ball Dam into its retaining slot before the
balls can roll down into the Center Trough. The balls will
be out of the way and you can easily loosen the two wing
nuts and two clip washers, then pull up on the robot body
to remove it (see Steps 4 & 5, opposite page).
The hole in a Ball Dam serve as a handy ball checking
feature. The hole is 40mm in diameter. This hole is used to
test the roundness and size of balls you use in the robot. If
you suspect a ball is out of round or too large, as indicated
by balls jamming within the robot, insert the suspected ball
into the ball checker hole. With your fingers, rotate it
around inside the hole to check all possible diameters of
the ball. The ball should have equal clearance through the
hole on all diameters. The ball should barely fit through the
hole without binding. It is also possible that a ball is too
small. In this case, you will notice a considerable gap
between the ball and the edge of the hole.
