Stamp controlled Robosapiens V2 IR help

seconika

I need help on how to solve this.
I would like to send IR codes to my Robosapiens V2 from my BS2p (40 pin)

As I understand it, I need to have a external cirquet that modulate the IR Carrier to 39.2kHz.
I was thinking NE555 IC ?

Then to the bigger problem !!
How to fix this ??

****************************

The V2 modulation scheme is similar to the RoboSapien V1 IR Codes. The IR Carrier is 39.2kHz. Data is modulated using a space coded signal with 12 data bits (data clock is 1200Hz, but actual data rate varies depending on the data). The V1 format is 8 data bits. I suspect the RoboRaptor and RoboPet use a similar encoding (with a different prefix)

For modulating the signals yourself, the signal looks something like this: Timing based on 1/1200 second clock (~.833ms)Signal is normally high (idle, no IR).Start: signal goes low for 8/1200 sec.Data bits: for each of 12 data bits, space encoded signal depending on bit value Sends the most significant data bit first If the data bit is 0: signal goes high for 1/1200 sec, and low for 1/1200 sec. If the data bit is 1: signal goes high for 4/1200 sec, and low for 1/1200 sec. BTW: the first 4 bits are always "0011" for the Robosapien V2 ("0001" for Roboraptor and "0010" for Robopet)When completed, signal goes high again.No explicit stop bit. Minimal between signals is not known.***********************************************************************

I think u can get much info from this forum http://pruim037.proboards107.com/·about RoboSapien.

There's a guy doing the same thing that u want but I think he is using BSX.

Hope this will help.

I have a Robosapien V1·($25 on Walmart)·and im looking to put a Homework board on it and expand what i have learn with my Boe-Bot, plus to have 2 robots ... do you have information on the proces to do this?

I will really apreciate if you guys can give me hand on this.

How about this low tech aproach ,,,,,

gut ur transmitter and use relays to activeate the buttons with ur BS2,,,,,,

but i think ur gonna have a problem with ur robo missing signals and getting out of sinc with ur program,,,,,...
