 | | GPS for RCX
|
| The standard RCX firmware with its serial protocol could not talk to a GPS, but LegOS could. With LegOS and a GPS we could make robots that could tell where they were. This would be way cool. I want a solar powered toy robot boat with GPS that can (...) (25 years ago, 10-Jan-00, to lugnet.robotics)
