Creating a 50 dollar Mindstorm.....
« on: April 01, 2009, 02:04:06 PM »
Hello Roboteers,


Little bit about my project.  I am trying to create an alternative for the mindstorm on a smaller budget.
My son already has an extensive collection of Lego. So  I decided to use Lego as a basis for the robot.

Lego is very versatile, quick and easy to build with. I have look at at the mindstorm products and they are well worth the money I must say.
But building a Robot controller and program it yourself is the extra fun ofcourse.

I am just starting with making the pieces fit to the lego system (not the nxt).

If somebody also experimented with this conversion..maybe we could share some ideas.

No not the -brick- .  I am using the 50 dollar controller and other selfmade parts.
I adapt it so I can use it with Lego parts and create a flexible kind of Minstorm with already bought Lego parts
The NXT is very nice but limited. So I am trying to build a flexible alternative.

I still use C programming as the main programming language.

Yes , next thing to get the light-resistors mounted on some brick. Have some IR modules ready also I have made 2 different models with IR , one amplified like in the tutorial and another model from another website..

I will post the test results. (all build with pots so I can use it also for line following)

I'm surprised more people don't just build their robots into lego chassis.  Especially the experimental living room sort.

A few years ago, some time before NXT talks were even out in the open, I used a lot the old Mindstorms kits. I still use them, but now I focus on the other type of robots. But at the time, being frustrated with the size and limitations of the RCX I thought about building a similar controller but smaller and cheaper and with more possibilities.
Since I didn't know much about microcontrollers, I chose something that was easy to program and small in size. Today I would choose a Mega168 or so...

So here is my microsize intelligent bricks that I've built at the time: Nemesis and Perseus bricks. If you Google the names you'll find more info about the micros. I have used them for line followers and mini sumo bots made out of Lego Technic and Mindstorms elements.

Check out the uBotino robot controller!

Lol, screw paying a fortune for the mindstorms kit when you can make your own augmented boards into lego mindstorms like things, and btw, these all look really awesome!!! Maybe i should try this out.

Nice work about the Lego-Bots you all...

I am already working on a smaller version , but same basic design.

Now I am trying to get some IR modules (self made, not Sharp) working.

Nice to know to have some fellow (Lego) roboteers who are also prototyping with Lego.

I've made like 20 robots out of legos like 8+ years ago. I got them to do fairly advanced stuff too, like the wavefront algorithm and a robot that shoots rubber bands at flashlights. They used the old HandyBoard from MIT.

Reminds me, maybe I'll upload a video or two of them . . . just subscribe to my YouTube account and stay tuned . . .
