Hi,
I don't have experience with the Tilted Twister but have a suggestion.
Is there a way to verify that the sensor is initially detecting the correct colors?

Hi, I have the DIST-Nx-Long-v2. It's range is from 300 to 1400 mm. Its the longest range IR sensor offered by MindSensors. -It's only a probelm if a person wants to measure something farther away than 140 cm (55 inches). It was holes for mounting to lego connectors and uses the standard NXT cable an...

Merry Christmas, The sensor's center of rotation was at X, Y coordinaters of 0,0. The scan was started at 90 degrees left (pointed along the negative X axis) and went to 90 degrees right (pointed along the positive X axis). The sensor would rotate and stop in two degree increments. After being stopp...

Yes. the ultrasonic sensor "sees" the nearest object in a fairly wide field of view. One technique is the rotate the sensor to find directions where the distance value increases significantly. The obect is then assumed to be the average of those directions. -This only works is there are no...

Hello, A while ago I did a comparision test of an ultrasonic and infrared distance sensors. Each sensor was mounted to an NXT device about 30 inches from a wall. One test was done with the wall only. Another test was done with a rectangular block of wood about 10 inches away from the wall and 20 inc...

(We're quite struggling with the ultralight sensor because it seems to measure the distance in a fairly wide range instead of one line straight forward.) I'm assuming you meant ultrasonic sensor. An infrared distance sensor (such as sold by MindSensors) has a very narrow "field of view". ...

Wow. You have made a lot of progress in one day.
Have you been able to test the program? Does it accomplish the desired task?

Hi,
There is an excellent NXT-G tutorial at http://www.ortop.org/NXT_Tutorial/
It covers a lot a basics like reading sensor values and how to have the program make decisions. That tutorial may help you get further along. Let us know if you are still stuck.

I'm only a little familiar with C. In NXC, for cos() or cosd() to work, must a header file be used? Something like #include <math.h> before the task main. If so, perhaps the include line or math.h is missing. Or maybe something is wrong with the "math.h" file. Could that be the problem? Dave

"Have you been able to determine what small steps are needed to lead to the final solution?" You mean, how to program it or? Before programming, it must be known what is desired. So a list of small steps generally comes first, and then programming is done to accomplish each step. Each ste...
