This is the second and new Version of my Claw Machine (Old Version)

As I announced in my first Version, the "new" Machine will be painted and setted up with an Arduino.

Step 1: Part List

These are the most important parts I bought for the Claw Machine V2:

Arduino MEGA, 2x 8 Arduino Relays, Mp3 module, accessories like cables and resistors

Wood colour grey, yellow, green, black

Claw Machine Assembly / Gantry

Step 2: Joystick Keypad

I built the keypad out of OSB-wood and I drilled some holes for the Speaker. Then I painted it and prepared the cables.

Step 3: Painting the Machine

I had some ideas for the Color design so I first tried it out in google sketchup.

Step 4: New Gantry Assembly

As I used LEGO in my last machine for the Gantry, I now buyed a cheap one of a German Arcade shop.

I rewired the whole Assembly for my purposes and added a Printer Port cable for easy plug and unplug. Watch the pictures to get yourselfes inspired.

̶i̶̶ ̶̶a̶̶m̶̶ ̶̶s̶̶e̶̶l̶̶l̶̶i̶̶n̶̶g̶̶ ̶̶m̶̶y̶̶ ̶̶o̶̶l̶̶d̶̶ ̶̶c̶̶l̶̶a̶̶w̶̶!̶̶ ̶̶i̶̶f̶̶ ̶̶y̶̶o̶̶u̶̶ ̶̶a̶̶r̶̶e̶̶ ̶̶i̶̶n̶̶t̶̶e̶̶r̶̶e̶̶s̶̶t̶̶e̶̶d̶̶,̶̶ ̶̶w̶̶r̶̶i̶̶t̶̶e̶̶ ̶̶m̶̶e̶̶ ̶̶a̶̶ ̶̶p̶̶r̶̶i̶̶v̶̶a̶̶t̶̶e̶̶ ̶̶m̶̶e̶̶s̶̶s̶̶a̶̶g̶̶e̶̶.̶ SOLD!

Step 5: Assemble the Gantry

In the Pictures you can see the assembled Claw Gantry and the Field for the Prices. There is a Printer Cable for easy plug and unplug the whole Gantry.

Now I tested the Motors of the Gantry, because it was selled as "not tested". But as you can see in the Video, e.g the up/down motor works, as well as the X and Y motor.

Step 6: Electronics

The most difficult part of this project is the programming. In the pictures you can see a few impressions of the Arduino setup. The PDF file is the Logic program that runs on the Arduino. All in all it is about 350 lines of code.

Step 7: Play With the Claw Machine

So here it is: The finished Claw Machine, now also with Plexi glass. I also uploaded a Video on YouTube which you can watch here.

epilogue

As easy as it sounds to build his own, realistic and working Claw Machine, we had really a lot of Problems that had to be solved, and the whole Project startet one and a half years ago. So if you are also trying to build your own crane machine, do not lose patience and keep working on it until it is as amazing as this one :)

Special thanks to CS for doing the whole programming and helping me to finish this project!

<p>Nice. But why using more than 1 relay module. 6 relays are enough, I suppose: 2 for each of three motors.</p><p>A question, What is the used power voltage for the motors? </p>
<p>I am using two relay cards because i also built in a <strong>light relay</strong> and a relay for a <strong>bell</strong>. And 1 relay already broke because i used it with 48 instead of <strong>max 30 volts</strong>. So now i have enough relays left and do not have to replace one. :)</p><p>I run the motors with 48V.</p>
<p>Think you for the response. </p><p>But, I don't understand : you run the motors with 48V and the relays can't support more than 30V. I thought each motor is driven with 2 relays for direction inversion. Are you controlling motors with something else.</p>
<p>You are basically right, it is a bit complicated. For each motor I have another two relays (with more capacity), which are switched on and of by each two arduino relays. </p>
<p>Really love the machine, looks like a lot of fun to use.</p>
<p>yes, it definitely is! Now, it also has Plexi glas.</p>
<p>I have all the parts to build one except the cabinet</p>
Just follow the steps of my first claw machine project, it is basically very easy to built. <br>
<p>where can you find the Gantry Assembly ?</p>
<p>There are a lot of traders, eg:</p><p><a href="http://bit.do/gantry1">http://bit.do/gantry1</a>, <a href="http://bit.do/gantrykit">http://bit.do/gantrykit</a>, </p><p>i got my gantry from a german trader for arcade parts.</p>
<p>If interested I have all the parts from a Big Choice claw machine. Just build a cabinet install parts and plug and play, no need to program. not2high2fly@optimum.net</p>
<p>Cool, mate! What was your budget for this project?</p>
<p>The Housing (wood etc.) and the screws was approx. 40 &euro;,</p><p>the Technic Stuff like the Arduino etc. about 100 &euro; + the Gantry Assembly 100 &euro;... So all in all the budget was about 250 &euro; or more.</p>
<p>So cool! Great job!!</p>
&quot;The claaaaaaw!&quot;
<p>i love it even if only for its sheer beauty</p>
I have the frame of a claw machine that I bought some years ago second hand. Always wanted to make a homemade machine (using the frame). Gonna try to use your instructable here for it. Thanks for the great tutorial!
thank you very much, I'm looking forward to seeing your own claw machine soon :)
