lego Nxt

we're taking first looks at the (just achieved) new programable lego brick Nxt.

everything's a little different eh better:

4 sensor inputs (instead of 3)
still only 3 motor outputs
the motors got builtin rotation sensors
communication via bluetooth or per cable (usb). no more infrared tower.

looks pretty robust. i still have to get use to the form of the motors though.

what else:

the firmware of the Nxt seems to be open source ([1], [2])

overview free, alternative, ... projects etc. using the Nxt: http://nxtasy.org/category/nxt-repository/ --

no knobs

take another look we noticed - it's no more lego anymore.

the Nxt brick itself has no knobs, assembly bricks don't have knobs either... (all in all there might be something like 6 parts with knobs in the whole set).

so you can't just put a lego character on your bot. You're brokenhearted, aren't you?

[edit]

gender

btw: lego thinks of all its robots as male. whether alpha rex (humanoid), spike (animal robot) or tribot (fahrzeugroboter) handelt, it's alwasy he... (at least on the german box).

we're planning to make a patch to fix this (stickers "she", "it" or "she/he/it").
