 | | My first crack at teaching Lego Robotics

I finally get started teaching in my son's 3rd grade class. I worked with students teaching them about gears, while my son taught other students to use the Mindstorms software. We spent two hours with 10 kids. I have to say it went pretty well. My (...) (26 years ago, 20-Jan-00, to lugnet.robotics.edu, lugnet.edu)

Thanks for the reply, I really enjoyed your book. My son (age 13) also enjoyed it. He's starting out using ROBOLAB, but your book has sparked an interest in C (like) programming. I look forward to a sequel. (...) (26 years ago, 6-Jan-00, to lugnet.robotics, lugnet.robotics.edu, lugnet.robotics.rcx.robolab, lugnet.edu, lugnet.robotics.rcx)

You could try using NQC (or MacNQC) and see if it works any better. I know in the long run you want to get Robolab working, but testing MacNQC would at least separate a Robolab-only problem from more general problems (serial port problems, cables, (...)

Hello, I'm teaching an RCX-based programming class using the Robolab software to a group of 19 4th,5th and 6th graders. I've been trying to get the Robolab software installed and running on the Powermac 5500/225s and 6400/200s owned by the school. (...)

If you are doing Robotics as a long-term project, go with one Team Challenge set for every 3 or 4 students. The ROBOLAB "Team Challenge" Set is the exact same set as the RIS 1.0, except that it comes in a nice plastic green tub with good storage on (...) (26 years ago, 18-Nov-99, to lugnet.robotics.edu)
