BALL THROWER

Design a machine to throw a small plastic ball as far as possible.

Think Like an Athlete:

How do you throw a ball? How can you use that to build this robot?

Think Like an Physicist:

How you you use leverage to get you ball to go further?

Try to mimic real-life machines that throw balls (like a slingshot or a catapult).

Mechanics and Movement

Try to Modify it

• Try changing the speed of the arm and see what happens.

​

• What happens if you increase/decrease the rotations?

​

• Adjust the position where your arm starts to see how that affects how far you ball is thrown.

Code for the Arm to throw the ball

CHALLENGE YOURSELF

Try to make your robot throw a ball as far as you are tall!

CODE IT!

Gears can be useful in making your thrower faster or more powerful.

Gearing up has a large driver and a small follower and increases speed but decreases torque (speed).

Gearing down has a small driver and a large follower and increases torque (power) but decreases speed
