I initially was sure that you needed 2 different crystals and 2 recievers to allow for 2 transmitters to work.
THEN, FIRST came out so confidently with their TEAMS WILL HAVE ONLY ONE CRYSTAL IN ATLANTA message, I read the manual again, and this time, I was sure that it was possible (especially reading Appendix E pages 11-20 or so).
THEN we tried to actually DO it... ...no good... ...I started scratching my head and it hit me: How does the reciever know which transmitter is #1 and which transmitter is #2? It can't know -- they're both on the SAME FREQUENCY!
Armed with this insight, I read the manual again. I stumbled on page 6-21 (this is from memory, so I could be wrong). Basically, there is a note on this page that says words to the effect of "all multi-transmitter modes require multiple (different) frequency crystal sets."
SO... ...now I am back where I started, Multiple drivers (with multiple transmitters) require multiple frequencies.
I don't know how FIRST is going to square this circle:
- They specifically talk about multiple drivers and transmitters in the rules, which I am now convinced that will require multiple crystal sets per team.
- They have specifically said teams will have 1 crystal set per team in Atlanta. By the way, even if we HAD multiple crystals sets, the rules as currently written only allow one receiver, so where would we plug the robot half of the second crystal set in.
What is a VEX team to do? Don't know... ...something has got to give.
...by the way, what did they do at WPI?
Did they require 1 driver/transmitter/receiver/crytal set or did they allow 2 per team?
