K'nex Claw Machine Game

video K'nex Claw Machine Game

Check it out guys, I made a K'nex Claw Machine Game for a class project using K'nex pieces, an Arduino board, and some miscellaneous things I found in a junk drawer. I will post a how-to-make of the claw since many of you have requested it. If you already have

I used duemilanove. I bought my arduino through my school, however. It could be because at the time I was also using the Arduino 0022 and 0023 software version. I would recommend checking your software. The libraries were changed in them.

how did you make your claw it would make a great instructable

Dec 12, 2010. 11:52 AMT86157 (author) says:

I'll post an instructable once I turn in this project to my professor. Basically I made a modified (and simplified) claw based on claws I found here on instructables.com and on youtube.

The only issue you may have building my claw is that you need broken Knex rods. Hopefully you have some without having to break any (I have had my Knex set for over 10 years now and have accumulated a nice collection of Knex rods that were accidently snapped in half). Broken Knex are still good!

That is awesome.

Can you show a few pictures of the claw as its a similar idea to something i was trying to figure out how to make, but failed

Dec 9, 2010. 4:39 PMT86157 (author) says:

Hope this helps.

I'll try to upload more pictures of the claw when I have more time. I basically used a lot of other people's designs I found on youtube to make a K'nex claw and simplified it to work with what I have. I actually had to use a K'nex piece that was snapped in half because it does not have the rounded end which obstructs the jaws of the claw.
