Today a catalog from Lego Educaton turned up in the snail mail. As I was
flipping through it I saw the "WeDo" system advertised in it. OK, so I guess
people who religiously follow Lego press releases would have known about WeDo
two weeks ago.... so I guess I am slow. Be that as it may....
It appears to have a "USB Hub" brick that connects to a USB port, and provides
what looks like two standard "new 9V motor system" connectors. The picture
shows a 9V 'M' motor connected to the brick. Googling for information, I turned
up a press release that talks about tilt and motion sensors that can plugged
into the same port. All of it talks to LabView. Hmmm....
So now I am wondering.... what are the possibilities here? Unless they went out
of their way to b0rk the USB driver, you should be able to plug about a zillion
of these into a snarl of USB hubs and talk to all the motors from the computer.
And what about other sensors? Might a NXT to 9V converter cable hook up a
regular NXT sensor? Now, I can imagine issues, USB devices are only allowed to
draw 500mA after enumeration if they follow the USB spec, so I could easily see
some kind of ultimate limiation on the number of motors you could run
simultaneously. But with a powered USB hub.... hmmm....
One thing I can imagine doing with it is having computerized remote control of
all the turnouts on a train layout.
Anyway, lot's of things to speculate about until Jan 2009 when it is supposed to
be available.

| (...) I think the software used to program the WeDo is written in Labview, the same way the software used to program the NXT is written in Labview. (...) The NXT to 9V cable is for the "old" 9v system that has two wires. The new Power Function (...) (16 years ago, 17-Aug-08, to lugnet.robotics)
