i didn't get it......... do you want your robo to pick up ball and put it in hole or to push it toward hole (like billiards)

Hi all,
I have also made a robot like you are thinking but i used for playing football using golf balls.There are many ways to hit balls.I'll suggest some of them:

1. You can attach a high torque motor to your robot with a metal peice as weapon.When you rotate motor the metal brick also rotates & hits the ball.This idea is for a beginner.
2.As you said piston.I also used this method for hitting ball.I made small solenoid gun using electromagnets which had a lot of power.It was 12v & 2amp.For more info search on google by the following names- solenoid gun,solenoid actuator & solenoid motor.This is a tough job & is time consuming but if it works it can add power to your bot.
3.You can add powerful pumps to suck ball(table tennis) & then through it can back when it is near hole.
4.You can use old cd racks.The idea is same as solenoid but it is less costly & easily done but it is now where near the solenoid.

I'll tell you more ideas later.I will have to recall them.
