 | | different output power at different ports?
|
|
I just confirmed that some RCX happens to allow various output power to different output ports. In my case, the port A tends to produce more power thru motor and the port C does. I then switched the two motors. The condition stays the same. (...) (19 years ago, 14-Jul-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi, if you have a LEGO serial port IR-tower and and you also got a RoboSapien, you can now easily control it from the PC. (URL) to Linux and USB tower coming later...) Feedback is appreciated. Enjoy, Pavel. (19 years ago, 6-Jul-05, to lugnet.robotics.rcx.legos)

Maybe you could use one of the output ports.
