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
