Robosapien_IR.zip contains source files, PCB + Schematic and IR codes specification. The design is based on 8051 core mcu (I use P89C668 in my build), only minor modification needed with other brands of mcu. The board receive command code from serial (uart) and generate IR code send out via onboard IR transmitter. You can use any C compiler to create and send command from PC or PDA, I m using LabVIEW for this part of application. Drop me email if you have questions or if you like to have the LabVIEW code, my LabVIEW code is running on Version 8.5.
