HITECHNIC INFRARED BALL (IRB1005):

The all new HiTechnic Infrared Electronic Ball (IRB1005), with four operating modes, is perfect for playing robot soccer or for as an infrared beacon for your robot to find. The well balanced ball contains 20 infrared LEDs giving full signal coverage and meets the new Robocup Jr competition requirements for the newly adopted Robocup Jr pulse modulated mode and is accredited by the RoboCup Jr Technical Committee. The IRB1005 can also be switched to operate in un-modulated (no pulse) mode to be compatible with existing RoboCup Jr requirements. Two additional HiTechnic modes, 1200Hz and 600Hz, provide added flexibility and detection ranges up to 5 meters or more (15+ feet). The pulse modulated IR signals make the HiTechnic Infrared Electronic Ball easier to detect in difficult background lighting conditions, a vast improvement over earlier models. The HiTechnic pulsed modes increase usable range and battery life. A perfect companion for the HiTechnic IRSeeker Sensor with its selectable modes tuned to the IRBall signals. The IRB1005 is 75mm (~ 3 inches) in diameter and requires 4 AAA batteries (not included).

NXT IRSeeker V2 (NSK1042):

Play robot soccer and zero in on your infrared (IR) beacons with the new and enhanced IRSeeker V2 (Version 2). You can use most TV remotes and LEGO® Power Functions remotes as beacons that the IRSeeker V2 will detect. With a specially designed curved lens and five internal detectors, the IRSeeker V2 has a 240 degree view making it perfect for playing robot soccer with the HiTechnic IRBall. The IRSeeker V2 has enhanced modes that detect modulated IR signals, including the new RoboCup Jr stepped modulated mode, and it filters out background signals giving superior performance in brightly lit rooms and sunny locations. The sensor returns the signal direction and strength making it easy to locate and gauge the relative distance to the target. A winning robot soccer combination when combined with the HiTechnic NXT Compass Sensor.

NXT COMPASS SENSOR (NMC1034):

Expand your NXT experiences with the new NXT Compass Sensor and add accurate navigation to your Mindstorms® NXT projects. The NXT Compass Sensor is a digital compass that measures the earth's magnetic field and outputs a value representing the current heading. The magnetic heading is calculated to the nearest 1° and returned as a number from 0 to 359. The NXT Magnetic Compass Sensor updates the heading 100 times per second. The Compass Sensor operates in two modes, Read mode and Calibrate mode. In Read mode, the current heading is calculated and returned each time to the NXT program executes a read command. In Calibrate mode the compass can be calibrated to compensate for externally generated magnetic field anomalies such as those that surround motors and batteries, thereby maintaining maximum accuracy.
