I coached a FIRST LEGO Robotics team last year and the team members used RIS. Before the season gets underway I would like them to learn Robolab. I've been working with it for a few days now and have a few questions. I searched the news groups and (...) (22 years ago, 24-Jul-04, to lugnet.robotics.rcx.robolab, FTX)

(...) Your approach is pretty common. As it turns out, you can (should) remove the wait time, also. Many people think they need to tell the robot how long to turn, or how long to go forward. It's like driving down the road in a car. You don't look (...) (22 years ago, 20-May-04, to lugnet.robotics.rcx.legos, lugnet.robotics.rcx.robolab)
