The coin-eating robot uses the principle of double-loop control motors. Put a coin on the robot’s hands and it will raise its arms, open its mouth and eat the coin into its body. Then he will lower his arms to wait for the next piece to eat.

Attach the yellow motor to plate 4 with the blue motor bracket using meson
screws.
Pay close attention to the direction of plate 4 which must have its notch at
the bottom left.
Make sure that the little yellow part of the motor that comes out is in the
first notch of the blue motor support.
Back of Coin Munch
To attach the blue motor mount to plate 4, the meson screws must be screwed in from the back of the plate.
-
Fit plate 11 onto the side of plate 4. Then screw onto the side using a meson screw.
-
Fit plate 1 onto the side of plate 11 that you have just installed.
-
Assemble the head (that you formed in step 4) with the body (that you formed in the previous step). To do this, fit the small stick at the bottom of the head into the hole that protrudes at the top of the body.
-
Fit the second plate 11 onto the right side of the Coin Munch and screw with 2 meson screws on each side.
-
Fit plate 9 under the Coin Munch and screw using meson screws.
Connects the wires from the battery box to the motor.
To do this, pass the ends of the wires through the copper notches on the motor
then twist them on themselves.
Be careful, the ends of the wires must not touch the metal motor otherwise it
will cause a short circuit.
-
Fit the feet (plate 14) and screw using two meson screws.
Glue the foam pads to the bottom of the feet. -
Fit plate 7 to the back of the CoinMunch (do not screw it in yet).
-
Secures the housing battery on plate 7 using two meson screws.
Screw tightly so that it does not interfere with the installation of the batteries. -
Place the switch (small black box) using self-tapping screws. Be careful, the wires must be downwards.
-
Place the blue tee on plate 12 using two meson screws.
-
Install the blue tee into the hole in the side of the CoinMunch and insert it over the plastic tip of the motor. It must be pressed all the way into it.
-
Place the axle at the head of the CoinMunch, in the holes provided. And add two orange sockets on each side (so four in total).
-
Place an arm on each side (plates 17) and add an orange socket.
Fix the rocker arm axle on plates 16 (lower left arm) and 18 (lower right arm)
with self-tapping screws (screw from the outside).
Install a green socket on each side.
- Insert the rocker arm shaft into the groove in the body.
Press it to snap it into place in the groove.
-
Pass a heading shaft through the hole in the lower arm and through the hole in the upper arm. Next, install an orange socket on the end.
-
Pass each white wire through the holes at the end of the lower arms on each side of the Coin Munch.
-
Place the front plate (plate 13) between the two lower arms and under the two white wires that protrude.
-
Place the 2 metal plates and screw them to the edge, with meson screws.
-
Place the metal rings of the white wires over the holes at the ends of the metal plates.
Place over the arc plate (plate 15) and screw it with meson screws. -
Install the two small round plates (plates 8) that you have left, on the same side. Screw them in with a selftapping screw.
Learning with fun
Discover the principle of CoinMunch: How does a piece of metal activate its
incredible appetite?
In the CoinMunch there are two metal plates that are very special. When you place the coin between these two plates, something magical happens. The two metal plates come into contact with the part and create an electrical circuit. It's a bit as if the coin said to the plates: “Hey, light up!” Electrical circuits allow electricity to move from one place to another. For example, when you turn on a lamp by flipping a switch, electricity flows through a circuit to turn on the lamp.
On the CoinMunch, when the two metal plates come into contact with the
coin, it activates a switch inside the CoinMunch. It's as if the coin pressed a secret button! And guess what ?
When this switch is activated, something really fun happens: the CoinMunch 'operates' its jaw and swallows the coin.
