Re: classpath and sound playback

Hi glen2008

What do you mean by "upload the wav file". I cannot get sound to play on my ev3 either. If you can explain I would be grateful.

Cheers
Nik

RotationNavigator Problem

For example when I say gotoPoint(200,0) and print the x coordinate on the LCD the robot travels in a line and stops and display 200. But if I suppress the behavior in the middle and ask the robot to display its x coordinates it sometimes displays values over 200 which is impossible. The funny thing ...

Proprietary protocol

LEGO says that they use a Proprietary protocol for IR communication. I guess you have to program at a very low level to achieve this If you are going to use different IR transmitter. I tried with a PDA and had no success.

Transmitting IR Signal

I'm not sure this will help. But One of my friends has developed a circuit for re-transmitting the IR signal emitted by the RCX IR transmitter. It can transmit the signal 360 degrees. It costs very little. Request if it helps.

When I use an Arbitrator with 3 behaviors with action() methods containing gotoPoint(100,100), gotoPoint(0,0) and Sound.beep() respectively. My robot travels between the two points and beeps whenever it hits an obstacle. My problem i...

I guess you are using the Timingnavigator. You can use a SensorListner for getting the value of the light sensor if it exceeds a threshold value, without using threads.
