(...) Hmmmm, that is a challange, because any cursory example leaves out the physics. I was just thinking perhaps if you likend polarity to a visual of a two lane highway. Trafic going in opposite directions. Flow and return. On the surface, (...) (20 years ago, 9-Nov-05, to lugnet.robotics.rcx.robolab)

I tried to create a couple of images to explain give children, age 10 to 12, a good understanding of what polarity is. They all know changing the direction of the motor. However, I am trying to provide more details without going over their head. (...) (20 years ago, 9-Nov-05, to lugnet.robotics.rcx.robolab)

(...) With the standard firmware, not that I know of. You *can* block all incoming signals by continuously broadcasting. Having a task repeatedly transmit a simple message endlessly means that the RCX can't recieve normal messages, possibly (...)

Hi, I am contemplating if it is smart way to intercept un-welcoming signal to the RCX, such as the remote shutdown, etc. ---...--- -------- Best Regards, Elizabeth Mabrey (20 years ago, 2-Nov-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)

(...) I found that either rotating a colour wheel in front of the sensor(with its distance LED off) in combination with a white light -or- using a coloured LED at a _very_ close distance works well; i.e. most materials give a marked response as long (...)

Hi, questions to all the guru out there. I have spent 20 hours on this roboarm. I am hoping to make it work like a color sorter. - pick up a ball wrapped in tin foil and drop it off at a container wrapped up in tin foil as well. - pick up a ball (...)

(...) I've discovered a thread in legofan (URL) that talks about new features of a possible RCX 3.0. Is there more information that can be handed out? - Dave (21 years ago, 22-Aug-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)

(...) This just was an forgotten bug that with older Robolab versions didn't harm. The solution is to remove the "Value of red container" and replace it by a blue container constant list ("User3") while selecting "RED". -Claude (21 years ago, 15-Aug-05, to lugnet.robotics.rcx.robolab)
