The latest NXTLOG Challenge is up. From the description:
"The MINDSTORMS NXT Camera Bot Building Challenge is asking you to create the NXT spy bot, paparazzi bot, photojournalist bot, or even a robotic fashion photographer.
We are looking for robots that can take still photos (not video), and we want you to also share the pictures taken from your robot’s point of view.
There's no limit on amount of LEGO MINDSTORMS NXT sensors, motors, NXT programmable bricks, HiTechnic sensors, or Bluetooth communication you can use on your MINDSTORMS NXT Camera Bot."
