Hi all:
I just got a Scout today in the Robotics Discovery set. Cool beans....about the second thing
I did was take it apart....two touch sensors, two motor outputs, IR port looks like it indeed wraps around,
and in fact I confirmed this with rcxCC. It will "see" straight out of it's top, as well as in front.
This is maybe the most interesting point. It will talk to the IR rcx tower! I can't make it do anything, but I
can use the diagnostic mode in rcxCC to return the "rcx" is alive, and the Version 10.00/00.34 So it is
alive. There is a led which blinks while it is communicating. The brick also has a "power" mode which the
documentation says will use a "booster pack" from Lego to extend the command set. This booster pack
available fall '00.
I saw somewhere it will communicate with an rcx...I think it was receive, or was it send, a number
between 0 and 12? Something to play with.
So, the communications work the same way, but it would seem the firmware is different
Notable differences: no aux 9v input, which means it is also missing the bump on the back of the rcx
which covers a bunch of capacitors (for filtering presumably). Other than that it is physically the same
size. Surface mount led's on the pcb indicate IR signal coming in, motors plugged in (chirps also), light
sensor "on", motor direction fwd, motor rwd, neat little slit to see the red led on (quite bright).
Interestingly, no serial number. 4 holes each side for pegs. Larger lcd display. No components
mounted on the back side of the pcb (I think the rcx has surface mount stuff both sides) so maybe it is
a simpler animal. Battery pack, cover identical. Lots of built in chirps, sounds, warbles. Very insect like.
Food for thought.
