Description. The pitching machine is basically a semi-automatic
high pressure laser guided cannon.The barrel is
actually a sawn off fire extinguisher screwed directly
to a one inch port poppet valve,behind the valve is the
pressure tank.(the 8 bars air pressure for the pitching
machine and the robot is supplied from a screw compres-
-sor).Mounted on top of the barrel is a double rod
actuator with a ring welded horizontally on the end.
Directly above the ring is a vertical magazine containing
ten balls.The balls drop one at time in to the ring ,the
actuator pushes the ring forward over the edge of the
barrel.After dropping down on to a small guide the ball
rolls backwards into the barrel. Behind and above than
the ring is a steel strip which holds the other balls in
the magazine until the actuator with ring returns.
