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 them to tackle
this project. Meanwhile, I would like to have a good idea how well the LEGO
light sensor can intercept the light from the roboball. What is the
reasonable distance? I am going to test it myself sometime this week. Hope
I will gather more input ahead from you experts out there.
