You mean like one of these? ;)

So there’s nog “legal” way to hook up the
low speed IR tower (fixed A-male connector) to the NXT brick. Also, I
repeat my concerns that Lego won’t be putting a host-capable USB solution in
the NXT brick. Until we have certainty about that, It’s all just guesswork,
and I certainly wouldn’t count on using the USB port as a means of out-bound
communications other than to a computer.

I’ve read the replies to this post, but I’ll respond here. As far as the cable
is concerned, the plug type is irrelevant; it’s just a standard. The real
determination of “master” and “slave” happens in the hardware/firmware. Could a
slave port be hacked into a master port in the firmware? We’ll see.
I suppose it would be easier, though, to set up a Bluetooth to computer to IR
tower communication protocol rather than try to run the tower directly from the
NXT.
Heh, this is an ivory tower academic project for me -- I’ve never built a robot
that needed more than one RCX! It’s like the time I briefly worked on a
communication protocol using the motor outputs and PWM as a code. :D

| I know everyone is psyched about the NXT, but on another topic-- does anyone have experience with the new compass sensor from Hitechnic? In particular, I'm wondering what chip they use, and how sensitive it is to non-horizontal placement. Also, can (...) (19 years ago, 8-Jan-06, to lugnet.robotics)
