Robolock Problems

[Simpfan]

I have build the Robolock in chapter 6. Sometimes take the robot card and somethimes not. And he don't see differences from the cards. He say something like wrong or something. I have copy the card and paste them on thick paper. So the card are not the problem. I have connected the wires correctly. But I don't think the touch and ultrasonic sensor work. The ultrasonic sensor not moving and nothing happens when I touch the touch sensor. I have used the brogram I have downloaded so there are not something wrong with the program either. Can someone help me.

It sounds like the light sensor isn't picking up the color squares properly. Check to see if, when the card goes into the robot, the color squares go directly under the light sensor. Also check to see that the robot stops the card each time a new color square moves under the light sensor.

All are correctly build and the card goes under the light sensor. But it not works. I have given up this and build a new model.

Hi,
    There could be several things happening, you might be pushing the card in to fast. Or if you stuck it down with tape the reflection might mess up the readings of the light sensor ( this happened to me). Also check the myblocks, there could be something wrong there. I'm no expert with the nxt but these could be one of the problems you are having.

   I hope you fix your problem Super robot wars  .
