(...) Here's what the kids can do to get started. Build a simple robot with a forward pointing light sensor. Place the activated roboball right in front of the robot and take light readings as the robot moves backwards. This can be done manually or (...)

I am new to Mindstorms, but not new to computer science. Anyway I am unable to load any program to the RCX robot using the dll. I have built the brickOS system using a egcs (v. 1.1.2) hitachi cross compiler on a Linux platform running the 2.6 (...) (19 years ago, 15-Jun-05, to lugnet.robotics.rcx)

Hi Mr Soh, Thank you very much for your input. Would you share your experience and views regarding tackling roboball with the LEGO RCX and light sensors, without other soldering electronic components. I have a bunch bright young 11-14 kids, I want (...) (19 years ago, 15-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

The rest of the LED's are infrared and invisible to the naked eye. One way to "see" the light (...) (19 years ago, 13-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

Hi, I got a roboball and wished to test it out for my group of kids to do a soccer game. When I first received it, one light bulb was lit. I tested it with the lego light sensor, but no reading. Then I connected it to a 9v . Unfortunately, now, the (...) (19 years ago, 13-Jun-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

You can use a counter running at 8x the cycle frequency to measure how many eighths the output is giving, and light an LED accordingly. For the magnetic sensor, I suggest (...)

I would like to be able to drive one or two banks of 7-8 LEDs off of the motor ports on the RCX. I know that there is a winker board that senses the motor level to determine what pattern to display. Can this be accomplished otherwise? I also want to (...) (19 years ago, 7-Jun-05, to lugnet.robotics.rcx)
