Hello this is Nevan I have just finished a project on lego dacta. It was of
some type of machine that transports little pieces of lego and it reads the
color of the block and puts it in a certain bin. I was trying to think of a
new project, but I only have three weeks of classes left to do it in, do you
have any suggestions? Thank you.

Build a system that communicates with Moresse Code. using flashes of
light.
You'll need to build two fo themof them, one for each of two computers
so you
can send and receive emessages from one to the other,.
Have fun.

Hi, Nevan!
One thing you could do if your project is not yet taken apart is to make more
of it. Why not make it a tester for potential employment? How fast can
someone load the bricks -- i.e., how many in a given time. Then how many by
color, etc. And have your program report back on the time, success rate, etc.
You could even create a graph of their progress. Gosh, the project could go
on forever!

Have you ever tried making a little trundle wheel, calibrated to read out
measurements? You can make it more sophisticated if you like, so it can
measure and draw a scale 3D model of any cuboidal solid(ie, a box),
complete with the dimensions etc printed out in the screen. All the best

Hi Nevan,
It would help to know which kind of legos you are working with. My
students have used LEGO TC Logo and made a washing machine, conveyor
belt, merry-go-round, robot with bumpers, slot machine, cars, and stop
light. They have used the Control Lab to make a robotic arm,
dynomometer, vending machine, wheel chair controlled by a LEGO joy stick,
and a draw bridge. All of the above projects were made from ideas in the
LEGO kits. John St. Clair

Hi, Nevan.
One of the activities I haven't got the kids to do this year and wanted to,
was to design a Mars rover that could withstand either falling into all of
the crators on Mars or all the high winds (300 mph.)
Also, my 3rd graders built a car that went 4.2 mph. Can you beat it?

Make a simple car that can climb a determined inclined board as fast as
possible. If you use a fast gear, it will net be strong enough. If you yse
a slow gear, it will be strong enough but not fast enough. The game is to
find the best gear ratio. Involves much gesr work, but no programming.

This inspired the kids to make a machine that rolled across the cards and read the pattern of blocks and reinterpreted it as a binary number. Similar thing to do with bar codes, I guess. =============================8=========================
Here are some ideas we have: I've always wanted to build a LEGO/Logo cube that can fold up and unfold itself. Maybe your sorting machine could use color markers to draw depending on what color LEGO brick it sees? Or could it draw on the screen to represent what it is "seeing."
Karen, who works with me, also suggested the following ideas:
Machines that. . . * Sort according to size. * That could build themselves -the moving mountain that takes itself apart and shifts. . . kind of like White Sands New Mexico. * Launch things -ping pong balls, paper airplanes, tops etc... Build a structure that . . . * Supports great weight (create your own method of testing) * Can withstand tremors (create your own method of testing) * Has four functions -make them really wacky things * Is organic looking / or is inspired by nature -could be tricky Youth Computer Center ============================9========================== Nevan, By now you probably have received lots of ideas, but just in case you're still looking, here's one. I remember that when LEGO-Logo was first being used in schools, that some groups did a lot of work making clocks. It might be quite a challenge to make a clock with an hour hand, a minute hand, and a second hand. If that is too easy, you might want to figure out a way to make it run steadily. You could make a pendulum clock powered by weights, a clock powered by elastic bands, a "clock-work" motor of some sort, or some other source (even an electric motor). You could learn about how an escapement mechanism works. If you decide to do this, please let me know how you made out. Dr. William J.

Design a robot animal that mimics some behavior in the real World or build a invention that can retreive a four square unit lego brick Square and retrieve the brick and return to its original position with the Brick.
If these are too adventurpus their are a number of good structure design Activities that are challenging. Build a lego structure that will stand :x Tall and hold :y weight (this could specified in poundage or it could be Something such as two specified dictionaries). Examine the structures of The most successful structures at this task. What conclusions can you Draew about structures? Connect to real world structures?
