Gripper with ATmega2560, stepper motors and servos

How often have you seen these automatons, with which you can supposedly get one of many cuddly toys very easily? You insert a coin, move the claw with the joystick, align it over the cuddly toy, and press the button. The gripper goes down, seemingly perfectly, the claw closes, the Krahn goes up and suddenly the cuddly
In this project, we show a way to build your own grabber. Some tinkering is necessary for the construction. A microcontroller with ATmega2560 is used.
