HiTechnic will begin shipping the IRSeeker sensor on Friday, June 22nd. More information on the sensor can be found here.
The sensor will be very useful for teams wanting to develop robots to participate in Robocup tournaments.
The sensor is compatible with NXT-G (firmware version 1.3), RobotC, and NXC. The sensor provides feedback in the form of a number between 1 and 9, indicating direction of a detected IR signal.
