Lego Release Mindstorms NXT Infrared Link Sensor & RF ID Sensor [Lego NXT Accessories]

For those of you into building Mindstorms NXT robots - which is far
removed from mere childs play - you may be interested to know that Lego
have now released two Mindstorms NXT accessories in the form of a
Mindstorms NXT Infrared Link Sensor and a Mindstorms NXT RF ID Sensor,
the former of which, somewhat tantalisingly, will allow your NXT robots
to actually control either other Mindstorms NXT creations or even Lego
IR remote-controlled trains and/or Lego power function motors.

According to the official Lego product pages, the two NXT accessories
are as follows:

Infrared Link Sensor for MINDSTORMS NXT!

Enhance your MINDSTORMS NXT creations with an Infrared Link Sensor! With
3 NXT-G blocks, you'll be able to build robots that can communicate with
other devices, including the MINDSTORMS RCX, LEGO IR remote-controlled
trains, and LEGO Power Functions motors.

Includes 1 Infrared Link Sensor.
Does not include connector cable.

RF ID Sensor for your MINDSTORMS NXT robots!

Another great MINDSTORMS NXT accessory for experienced programmers! Add
an NXT-G program loop that needs a specific transponder to run. When you
have the key transponder, only you can start the program - use multiple
transponders to run multiple program paths!

Includes sensor and 2 RF transponders!
Does not include connector cable.

Both accessories come without the all important NXT Intelligent Brick
and require the Lego Mindstorms NXT set #8527 in order to run and will
set you back around pound sterling33 and pound sterling40 for the
Mindstorms NXT Infrared Link Sensor and a Mindstorms NXT RF ID Sensor
respectively. Extra keyfob transponders for use with the latter are also
available for just shy of pound sterling25 for a pack of 10 units.
