Hi All, I have a couple of quick questions. 1. The help in Robolab says I can select a program from the programs list and press F10 to delete it. Every time I do this I get a message saying that the folder is locked. I've tried everything I can (...) (23 years ago, 1-Oct-02, to lugnet.robotics.rcx.robolab)

A couple people have pointed out how the new motors on the RC Buggy seem to be very fast. So with the Workshop 3D challenge coming up, I wanted to see how they compare to the Mindstorms mini-motors. To test them, I started by hooking a rotation (...) (23 years ago, 30-Sep-02, to lugnet.robotics)

|
|
(...) The IR protocol is slightly different. While IRDA only sends short pulses the Lego Tower sends a signal for the whole time slot. It is very unlikely that one can get them work together. Jochen (23 years ago, 30-Sep-02, to lugnet.robotics.rcx.legos)
