Looks like I was a bit hasty...

For a better understanding: Lego Mindstorms is the name of a product series by the toy manufacturer Lego, containing a programmable Lego brick (RCX = Robotics Command system, or NXT) as well as electric motors, sensors and Lego Technic components (toothed wheels, axes, hole beams, pneumatic parts, etc.) to design and program robots and other autonomous and interactive systems.

Ok, though I'm not a child anymore:

... well, ok, this is not mine...

but this is what it could look like :)

... not at all childish, don't you think?
