Write Java code for LeJOS mindstorms robot

Hi there, Looking for someone familiar with the Lejos mindstorms EV3. It's a robot made of LEGO which works on Java. The robot has a few sensors and I would like to use the infrared sensor. You can find the user guide in your own language here: [login to view URL] If you are familiar: I need to write 3 small tricks the robot should do. Some are easy, some more difficult because of the sensor. 1. The robot has three led's in the colors green, red and orange. I would like to have a "disco effect", so all lights go on and off very fast. 2. I would like the robot to make a sound when he detects a movement (already have some code for this,). 3. When he detects a movement, I would like the robot to move along with it. So really follow it, or rotate in the same direction. The robot looks like a man and we want to let other robots pass (women) and then he should be "watching" them. I use Eclipse. Let me know if you can help! Thanks.
