Okay, confession time: I picked up a cheap V1 Robosapien to hack
around with on Ebay. It's actually fine, except that the power switch
has failed mechanically. But repeated Googling found me nothing on the
power switch, its wiring, or where I could buy spares (the information
is probably out there, but I'm just not hitting the right search word
combo).
No big deal, I decided -- it wasn't difficult to chop the switch out,
reverse-engineer it, and... get interrupted for a couple months, before
I soldered the new switch in place. After which, I can't find my
reverse-engineered wiring diagram, *or* the original switch. D'oh!
It's nothing terribly complex -- the original was just a DPDT latching
PB with a bit of PCB cross-connection that I could duplicate easily with
a bit of wire. Unfortunately, I don't remember the setup quite well
enough to wing it, and I don't feel like experimenting until I stumble
over the right combination.
Just to ice the cake, there are two wires of the same color, and (IIRC)
the same PCB label, but AFAICT were completely separate electrically --
that made no sense, especially given how well-organized the RoboSapien
appears to be, overall.
So now I'm doing what I should have done the first time 'round, and
hitting up C.R.M. groupmind: anyone know where I could find a
fully-detailed wiring diagram of the RS's power switch circuit?

Hi David,
here's a picture of the inside of my RSV1 that shows the power switch PCB
somewhat
clearly, I hope. I did some modifications, among others on the two yellow
wires going
to the speaker, but the wires to the power switch PCB, and the power switch
PCB
itself are still original:

I think you should be able to figure it out from here - if not, please post
specific questions,
I can do some simple measurements (voltages, open/close contacts of the
switch) and/or
take additional pictures.
Good luck!
Peter
