(...) I'm using accumulators (you called rechargable batteries) because a lot of toys are using mignon batteries and so I have about 20 rechargable batteries and a processor charger for loading these in a short time... The problem of this (...) (25 years ago, 3-Dec-99, to lugnet.robotics.cybermaster)

So the action radius was about a maximum of 3...4 meters an d the connection was interrupted seveal times. My measurements (...) (25 years ago, 6-Dec-99, to lugnet.robotics.cybermaster)

You are right the nominal voltage of this recharable batteries is 1.2V but I tested the voltage of a just refreshed batterie under load and then the real voltage was about 1.25 (...)

At one point I had so many problems with "dead spots" with my exploring rover (that needs to communicate with the map making/route finding software running on the PC), (...)

(...) I would suspect that antenna placement, and possibly considering a different antenna design, would make a huge difference. Look in some radio books for things like Yagi designs. Give you much more range, but also make the antenna very (...) (25 years ago, 14-Dec-99, to lugnet.robotics.cybermaster)
