I never heard of Quantum Torque, did you? Well, their website says that “Quantum Torque is a independent Australian internet shop which aims to provide components and products that can be used for robotics and embedded electronics projects”. The picture above is a ‘cball Infrared Ball Sensor’ - 8 x infrared photodetectors arranged in a 180 degree semi-circle. It has I2C interface, and their site has NXT-G and RobotC examples. Other products on their site is a ‘iball’ (1 x infrared photodetector with NXT socket) and an NXT breakout PCB board. Check their site for details.

NXTasy Challenge #3 - The ANxT!
Monday, July 9th, 2007
NXTasy challenge #3 if finally annouched! Your mission will be to build an NXT ‘Ant’ or ‘ANxT’ in short.
Ants are remarkable little creatures, capable of lifting weights several times their own body weight (if you search the net, you frequently find sites quoting that ants can lift 10, 20 and even 50 times their own body weight. However, I could not found a scientific proof for these values…).
The goal of your ANxT would be to move an object (the ‘weight’) a distance of 1 meter without touching the floor. The grade will be 50% determined by the object weight/ANxT weight ratio, 30% by the mass transfer rate and 20% by how much your ANxT is, well, ‘antish’…
Oh, and the object must be bigger then your ANxT in all dimensions, did I mention that already 
?
The full details, rules, submission procedure, deadline etc. are here.
