Holidays

Yessssss! for christmas my dad gave me another NXT! I have just finished a (flawless) BlueTooth NXT-NXT remote controlled car and I will post it soon. Please leave suggestions in the comments section if you want me to build something that has to do with two NXTs. I also got the LEGO MINDSTORMS Idea Book authored by some of the The NXT Step's contributors, and it is a great book. I would recommend it if you like NXTs and reading. And they encourage you to respond to them if you have a question.

FLL Competition at Intel

The A.E.R.O. Cows competed at Intel Jones Farm Dec. 15 and we got these scores:

1st round - 190

2nd round - 275

3rd round - 225

The second round tied for 3rd best table score with another team out of about 20 teams.
We scored high in the other topics too, and overall they were enough to get us to State! Woohoo!

OctoBot

Here is a cool robot I made a while ago that uses it's 8 legs to walk fairly speedily. I designed it originally to enter the NXTLOG BugBot building challenge, but never got around to posting it and thus ran out of time. However, I am still allowed to post it on my site, so here it is:

Modular Multiplexor

Here it is! the project you've all been waiting for! (Or at least that I have been waiting to post ;) ) Anyways, so here is how it works. There are 2 modules. 1 is the base, which is basically a bit of technic with wheels on it. Then there is the top module, with the motors and NXT on it. This one is a bit more complicated. There are 3 motors and 1 of them slides the other 2 forward and backward. When they are in back position, they engage with the base's wheels, and when they are forward they engage with the base's attachments. As there are 2 motors that slide forward, there are 2 attachments. And just so you know, the attachments are built into the base so the only change-out time is when you switch out the bases.

So picture this: you send out your robot, it uses it's 2 motorized attachments to solve 2 missions, it comes back to base, and in about 2 seconds you move the top module to the next base, with different attachments, and you send the robot out to do it's next 2 (or more) missions. If this explanation doesn't make sense I won't be surprised so please comment if you have a question.

PackBot NX

Here is a video I seem to have forgotten of the PackBot NX. I recently was playing around with iMovie and edited it a bit (added sound and stuff).
