Lego mindstorms-what to do?
« on: February 20, 2011, 08:47:53 pm »
For a couple of years now, I have had a Lego mindstorms robotics set. However, the infrared transmitter for sending programs to the robot is broken, and I have Not been able to use it until now, when my friend gave me a transmitter he doesn't use anymore. Now that I can use it, could some one suggest to me a challengeing task I could get a robot to do?

Programming a calculator game.

But seriously I don't have any clue. I unfortunately never had the chance to get a robot-type lego set back then, because my mom didn't want to spend money on batteries and stuff, and I don't know about new sets since I mostly played LEGO's around 1990-99 (Yay for Dark Knights and Blacktrons!)

You are in luck :) I actually was *introduced* to the whole concept of programming by Lego Mindstorms.  Some good exercises when you are starting out is building a little car that moves forwards and then backs up and turns if it runs into something.

If you want a real challenge. (Depends on how good you are at it.) You could try to make a segway. I've seen it done so I know it's possible.

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

Let's see, I'm assuming you are talking about those old RCX ones.  Personally, I have the NXT, but I would try and get it to talk to your calc over infrared.  Either that, or it's a 2 wire interface, I think (One is probably a safe bet to be ground) in which case, splice one of the cables, and talk to it via the link port.  That is assuming the RCX can talk via pull-up resistors, I'm not too sure about that part.

Make a line-following robot. ;D

I had a course at school called "LEGO Blocks and Robotics" that used RCX sets. We were in teams of two (I was with my mom, somehow) and we had to make a bipedal walking robot. Of course, at first, the robot kept falling, but at the end it walked a good distance without falling and I had 100%. So, IMHO, that's a good challenge :)

All I had was this cheap "micro scout" thing, with only an infrared sensor and a single output motor :P  So I wasn't able to do much with it...

I actually have a micro scout too. I wonder if I could use the infrared link and make it a third motor. It would sure be bulky, though.

The Segway seems like a really good idea, except I don't know how I would get the robot to detect how much it is tilted.

I also have a spybotics (the purple one) but one of the wheel motors retired, so I haven't touched it in years :P

Please don't even try to suggest something like this to me.

Didn't they make a lego robot a while back that could make more lego robots?

I've decided to try making a Segway robot. I've just built the actual robot, but I am waiting for my mom to finish using the computer so I can program it. Once it works, I will get a video up of it running. I may try to get the robot to turn, as well.

All I have to say is good luck :) A segway might be one of the harder things you could choose to build and program, but I really hope you get it working :)
