Yesterday at the second hand clothes market (the used (and in most cases, broken) toys are occasionally appearing there) I spotted an RSv1 remote. It had a strange yellow/red color scheme (not a classic WowWee black/white one) and without a battery compartment door. But at less then $2 price I bought it just immediately. Later at home, after a disassembly, washing the case and rubber keys and reassembly, it proved to be fully functional (I tested it with my Femisapien).
BTW the range of control impressed me much. Femisapien relyably reacts to the commands all around the room (small room in fact) end even when remote was aimed to the opposite direction to that where Femi stands or to a ceiling (so, even a reflected signal is readable for Femi)! Simply not comparable with a range of control from a PPC (Asus MyPal A696).
And after a short euphory walking my Femi around a room, I realized that standard for WowWee "martian" approach to defining "left" and "right" (you know, what I mean ) is not awkward, it's just unbearable frustrating. I remember, this theme was discussed before here at robocommunity, but no practical recommendations was given. Just a theoretical thoughs about reprogramming the PIC of the remote and doubts about a practical possibility of rewiring.
So, I opened a remote again and spent quite a time deciphering the keyboard matrix and then rewiring it to swap left and right keys.
Now I'm happy walking my Femi everywhere I want just like any other remote controlled vehicle. And I can say: It's completely real to do in just one evening by anyone, who have some experience in cutting the PCB tracks and soldering a wires !
If anyone is interested, I can share more detailed info on the RSv1 remote keyboard matrix and it's rewiring to swap left and right buttons.
