Just to be clear,
tethering should be okay. I didn't deal directly with the 05 robot, but as I recall we were using the 05 robot as a test robot in 06 and maybe 07. But if you are using the
radios, there were some changes, but I think it was between 07 and 08? Also, with the radios, the robot and controller need to have the same number frequency, which tethering will help set.
Don't hit the "prog" button on the robot controller -- that clears the program!
If you lose the code, or want to try new stuff,
Kevin.org is still around, with codes going way back in time. (Not the Kevin above.) His "example" codes are complete, but you'll have to use MP-Lab to compile them. His basic codes have simple joystick driving available, but obviously anything else you'll have to write for.
