Picture of Robot Surgery Game

Not just anyone can perform surgery. It takes decades of schooling and years of experience to become a surgeon. Fortunately, most anyone can not only play operation, but build their own custom operation game. In this way you can practice removing unnecessary bits from whatever sentient life-form you wish. You may not get a surgical license for this, but you will surely have a better time than attending medical school.

Step 1: Go get stuff

Picture of Go get stuff
You will need:

- 4 "AA" Battery Holder (Model: 270-391 | Catalog #: 270-391)
- (x2) Red LED with Holder (Model: 276-084 | Catalog #: 276-084)
- 75dB Piezo Electric Buzzer (Model: 273-054 | Catalog #: 273-054)
- 220 ohm 1/4W 5% Carbon Film Resistor (Model: 271-1313 | Catalog #: 271-1313)
- Enercell® "AA" Alkaline Batteries (4-Pack) (Model: AA-4PK | Catalog #: 23-849)
- Robot operation template (see attached)
- Operation pieces
- (x4) 1/4" x 1-1/14" bolts with nuts
- (x4) Washers
- (x4) Rubber bolt covers
- 11 x 17 mat board.
- Aluminum foil
- Two zip ties

Step 2: Glue

Picture of Glue
Cover your mat board with spray glue and center your robot cut template on top.

Smooth it out to get rid of air bubbles and make sure it is attached well.

Step 3: Cut

Picture of Cut
Use a craft knife to cut out the inner pieces by following the outlines.

Step 4: Glue some more

Picture of Glue some more
Flip your board over and spray the back with glue. Firmly attache a sheet of aluminum over top of the entire back side.

Step 5: Aluminum edges

Flip the board back over. Trim away the excess aluminum foil from around the board's edges

Carefully cut the inner shapes and fold the aluminum up and over the lips of the opening onto the picture side.

Step 6: More holes

Picture of More holes
Cut two small 1/4" holes at the end of the robot's antennae.

Step 7: LEDs

Picture of LEDs
Pass your LED assemblies down through these openings and securely fasten them in place.

Step 8: Bolts

Pass one of the bolts through from front to back.

Cut a 12" piece of wire and expose three inches. Wrap the exposed wire around this first bolt. Put on a washer and then fasten it down with a nut.

Pass the remaining bolts through, add washers and fasten them in place with nuts.

Step 9: Buzzer

Picture of Buzzer
Make a loop of tape and stick your buzzer to the aluminum side of your board.

Step 10: Tweezers

Picture of Tweezers
Cut a two foot section of wire and expose about two inches worth.

Solder this wire to the joint of your tweezers.

Step 11: Wire it up

Picture of Wire it up
Wire the red wire fastened to the bolt to the red wire of the battery holder.

Wire the two red LED wires to your 220 ohm resistor.

Wire the red buzzer wire and the tweezers wire to the other side of the resistor.

Wire together all of the black wires.

Step 12: Clean it up

Picture of Clean it up
Cover all of the exposed wires with electrical tape so that they can't cross.

Bundle together all of the wires with zip ties, except for the tweezers wire.

Step 13: Finishing touches

Picture of Finishing touches
Put your thread covers onto the ends of each of the bolts.

Step 14: Batteries

Picture of Batteries
Put your batteries into the battery holder.

Now, when you touch the tweezers anywhere on the aluminum foil, the LEDs should light up and the buzzer should buzz.

Step 15: Game pieces

Picture of Game pieces
Drop your game pieces into the appropriate holes.

Step 16: Play!

Picture of Play!
Try to remove the pieces without touching the sides of the hole with the tweezers. If it buzzes, you lose your turn. The person to pull out the most pieces wins.
Can you do it without the screws?
I'm a bit confused on the circuitry...do you have a schematic I could follow?
Wire from bolt --> Positive 4.5V

Positive wires from LEDs --> one side of resistor

Positive wires from buzzer & wire from tweezers --> other side of resistor

All ground wires --> Just connect them all together.

When the tweezers touch the foil, it connects the bolt wire and the tweezer wire, sending electricity through the resistor and into the LED and buzzer.

Hope this helps.

The attached .eps file is just an outline, not an actual colored robot. And where do you get the operation pieces?

Great job on the instructable!

Awesome! Will be making this soon!

This might be a good starting point for a PICAXE project. Each opening could be isolated and connected to a different input. You could then program the PICAXE to keep scores for Player 1 and 2, or you could make the game harder by telling the player which item they must lift next.

I might use this idea with my students. They can bring in the old nokia ringtone tunes, their choice of patient etc. Very cool!

All the software can be developed as flowcharts.

yes doctor.....there's my gear and i pain!!!
Love it! I'll be on the lookout for an old Operation game at a yard sale.
