|For playing on carpet (which is recommended,
otherwise the ball will roll too far), four spiked “golf shoes” on the
corners provide grip into the carpet to keep the arm from sliding around
when it swings.
Attach a wire from the motor to port A on the NXT brick.
|Design your own “hole” or goal for the ball using
LEGOs or whatever you have. Here is one way to make a "hole" using parts
from your NXT set.

When taking this project apart, the blue pegs are very
difficult to get out of the axle extenders.
Never use your teeth! Using your teeth will ruin the pegs.
Try unbending a paper clip as shown and then pushing the peg out from
the other side. Keep the paper clip in your NXT kit as a tool for
things like this.
The golf club shown
here always hits the ball rolling on the ground. Can you design an
alternate club to use for “driving” that will hit the ball up in the
air? A tee of some kind to balance the ball on might help too. Make
your two clubs easily interchangeable so that you can easily switch
between the driver and the putter.
robot arm would hit the ball harder if it were taller (and the arm
longer). Can you design a taller version? You might need to also
make the base larger to keep it from falling over when it hits.
