Summer!

Yaaaaaay..... After having to do school into the summer, I have officially finished! Which means I will be working on some new projects (I am testing out some now), although I won't be able to make all of them until I get some much needed parts. I also am going to work really hard to finish my website, and remember what I said about something happening to this blog? Well those changes should take place this summer. So yeah I got a pretty busy summer planned. Oh and by the way something else exciting has happened and you will find out what it is probably by the middle of July.


P.S. I am really trying to find a name for my website and if you think of one either email me: (nxtgeek@gmail.com) or comment.  Thanks!

4 Output Multiplexer

I am testing some different multiplexer mechanisms for one of my future projects (it's really cool) and so here is what I came up with. It needs some improvements but it is just a design, the one I will use for my project is going to be smaller and more accurate, anyway here is the video of it in action:

Mobile Skid-Steer Arm


This is my entry into the unofficial NXTLog Mobile Arm Building challenge that me and a couple of other NXTLogger's started. It wasn't as big as I would have liked it to be but due to the amount of parts I have I couldn't make it bigger. Basically it is a moving arm that can drive with two motors and lift and grab with the other giving it an extra dof (degree of freedom). The chassis (pictured below) was built strong to support the skid-steer drive which if not built properly would have bent the axles.


The grabber/lifting mechanism (pictured below) was designed to first grab something then lift it a few inches off the ground. I geared the lifting mechanism down so that it could pick up heavier (approx. 1.5lbs) objects.
I could probably explain how this works in a lot more detail but that is why I made the video. Enjoy!

Stay tuned for some awesome projects coming this summer!
