The frame of the candy claw machine is made using aluminum and acrylic sheet.

All the electronics, sensors and actuators used in the project are controlled by evive.

For visual feedback, there is a 16×2 LCD displaying the instructions and the time remaining during the match.

The Claw making is decorated with RGB LED, which also tells the user about the time remaining.

There are also limit switches for X and Y directions to prevent any damage. To move the gripper in XY direction, the user uses the other joystick similar to gamepad controllers.

For the XY movement of the gripper, we have used the lead screw mechanism which is driven by stepper motors.

There is a limit switch on the top of the Gripper which prevents motor motion when gripper comes close to the Motor. We have used a servo for gripper open and close mechanism and a motor, thread and a pulley to move the gripper up and down.

The user can control the gripper open and closed position by moving the joystick left and right and move the gripper up and down, by moving the same joystick up and down.

After inserting the coin, the user gets 2 min time to control the gripper, catch as many candies and drop them into the left corner from where the user gets the candy out.

The user can start the game by inserting a coin into the coin machine.
