 | | explain polarity to middle school children

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)

I have been working with the RoboLab programs created by the Convict School to help me with a project of mine and to teach myself RoboLab. Recently I found the new work done by the school in 2002 (URL) download the files and placed them into the (...) (21 years ago, 13-Aug-05, to lugnet.robotics.rcx.robolab)

| | RE: good way to detect the proximity of the RCX?
|
|
Yes, that requires the RCX to receive. What I am looking for is a function which is much like the "is RCX in view" in the direct mode. This function allows the IR tower to detect any RCX in range, even the RCX is in in idle state, but just on, .... (...) (21 years ago, 10-Aug-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)
