INTRODUCTION
Candy Claw Machine
You have probably seen a claw machine game at a movie theater, video arcade,
shopping mall, bowling alley, or other entertainment venue in your area. They go
by many names including claw cranes, toy cranes, and skill cranes. They usually
consist of a large, clear box filled with prizes like toys and stuffed animals. Inside
the box is a claw that moves in three dimensions: forward and backward, left
and right, and up and down. The player operates the claw with either push
buttons or a joystick controller on the outside of the machine. The player pays a
fee to try their luck at moving the claw to the correct position and grabbing a
prize. Then the claw returns to its starting position and drops the prize into a
chute where the player can get it.
With this kit, you can build a mechanical claw machine. Your machine
requires no electricity or electronics — just simple machines and the power of
your hand. Here is an overview of the different parts of the Candy Claw Machine:
