Doesn't Robolab have some way of starting external applications?
You could possibly setup a PC with IR-tower, which would receive
a message from RCX
(http://www.idi.ntnu.no/~petrovic/ir/ - are the Robolab messages
compatible with Mindstorms RIS? - I cannot find it anywhere),
and as a follow-up it would send some message to RoboSapien
- a bit tricky, but perhaps even a Robolab program could trigger
that communication.
Also note that this program sends the control commands to Sapien
only from the IR-tower, not from the RCX.
That would be another interesting project for a small Brickos program!
just to get started:
from the H8/300 manual
(http://documentation.renesas.com/eng/products/mpumcu/e602080_h83297.pdf)
it seems that its serial port doesn't really allow to control TxD,
or does it? (see the schematic on page 190)
it keeps sending the content of TSR with parity and stopbits after
copying it from TDR.
on the other hand, on the bottom of page 196, clearing the TE bit results in:
"the transmit function is disabled, the TxD pin can be used as
general-purpose I/O port." however, I am not sure what they mean here...
but...there seems to be a nice synchroneous mode without startbits/stopbits
and parity (page 224), and the baud rate should be possible anywhere between
110 and 38400 (??? - page 204 right - are we running 16MHz?), so the
RoboSapien 1200 baud impulses could be possible to generate...?
then only set the proper ports (page 191) to proper values? hopefully...
sorry for being cryptic, hope it inspires someone.
p.s. a really nice feature of Robosapien is that when it is in the middle
of executing some command and a stop message arrives, it stops - so you can
make a step of almost any length... just thinking of making a program
that can use camera to navigate the creature to pickup a cup no matter
where you put it... but now I have to turn off for a while
