Finally got my Mindstorm NXT running today. Well, more like spinning around in a circle. It should run along, detect a ball, pick it up, and return it back to where it started from. Instead, it runs along, gets the ball, and then spins uncontrollably around the room like a drunken spider Would explain why mine runs along, grabs the ball, turns round and then spins round the room like a drunken spider 
Sy reckons the guidebook has built-in bugs so you have to figure out what it's really doing and fix it. And they say it's for Ages 10 and over, maybe there's an upper age limit too
