Do you know this classic wooden labyrinth game with two knobs for X and Y rotation?

So, I've decided to modify one by connecting two standard servos to the knobs and let a microcontroller (ATmega32) play the game.

- To CarlS www.instructables.com/id/Servo-Controlled-Marble-Maze/ for inspiration.
- To the AVR freaks www.avrfreaks.net especially Dean (aka abcminiuser) for his excellent tutorials.

Please, feel free to write ideas for improvements and modifications.

Step 1: Materials, Parts and Tools

I found all the materials for this project laying around at home and there were no plans nor designing. I just took the materials and thought how I can assemble them altogether.
You can use other materials and basically it's a good practice to design and make plans beforehand.

1 wooden Labyrinth - 280/230/60 mm
1 wooden board - 400/350/20 mm
4 pieces of wood – 30/30/10 mm
2 pieces of wood - 150/155/10 mm each
2 pieces of wood, L shaped – 120/27/4 mm each side
4 pieces of wood, L shaped – 34/32/8 mm & 18/32/8 mm each
600 mm long strong silk string
8 pieces of rubber – 30/30/1 mm each
4 L brackets, stainless steel – 32/32/1.5 mm each
8 bolts (40/5 mm) with nuts and washers
A bunch of small wood screws and nails
a piece of paper, A4 for example
contact adhesive
insulating tape

2 Hitec HS-311 Standard servos
AVR ATmega32 and a programmer – I use the AVR-LIP (EC-AVR) by DeccanRobots
2 straight switch knobs
1 breadboard
Some wires and pins

saw, screw-driver, hammer, sharp knife, scissors, clamp etc.

This is awesome! I used to own one of these when I was much younger. Now I can win every time haha.
You need a video showing it beat the game, not just starting.
I've seen something similar a few years ago where the labyrinth was controlled via a Wii fit board. A very cool project indeed. <br><br>Would it be much harder to do something similar with a foosball table? I've seen a basic one made entirely out of wooden dowel rods and thin, flat wood pieces for the players. It would be interesting to build a scaled down model with only a couple of rods for each team, then set up two microcontrollers to battle it out. Likely a LOT more complicated than it sounds but it would be a great project.
or, if you had an NXT set, jailbreak a friends iPod and use LegoDrive :P to control the NXT directly...
Nice project, I'm trying to do the same thing.Just have a question or a comment realy.You didnt have any problems keepn this calibrated?
it is a funny video
Hi, Can you please tell me what kind of servo fittings did you use to interface the servos with the switch knobs. Thanks in advance for your help :D
Hi, you can get the answer from the photos on step 2 and step 3 :)
&nbsp;If you transferred the idea across to Etch-a-sketch, ensuring that the servos were fast enough and if you had some very good programming and electronics knowledge, you could maybe make an Etch-a-sketch CNC monitor that refreshes every four seconds or so. It would look great (even if practicality would be low).
&nbsp;Haha, i found one of those Labyrinth Games for $3 at a yard sale a few months ago! WOO!!
I too just got one at a second hand store. I think this was very well done but destroys the modern-day purpose of a fun game using no electricity or batteries or motors. Just wood metal and springs.
Great job. Have you thought about making it controllable from an iPhone/iPod Touch using the accelerometer?<br />
I've got no iPhone/iPod, but I'm gonna check any kind of controller with this game. thanks :)<br />
&nbsp;Very good project, now add a wii nunchuck! (ebay, very cheap ones there)
&nbsp;Coolest instructable I've seen in a while.
Thx ☼<br />
&nbsp;I've never actually seen one of those ball labyrinths before. &nbsp;Very fun looking. &nbsp;
