(...) As I've said, I think the new Lego Technic gear motors are a great deal. They're inexpensive (about $18 each), they seem to be quite efficient, and they run well directly from the HB power supply. If you're building your robot out of Legos (...)

I was just wondering if there's any way to disable and remove the LCD screen and still have the HB work. My design does not require the LCD, so if i could remove it my robot would then be a little more balanced. Every time I remove the LCD my (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

(...) What you have is most likely a 9V DC motor, not a servo. As far as I know, there is no such thing as a Lego servo motor. The four-contact plug is a Lego standard that allows changing the polarity simply by rotating the plug 90 degrees. There (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

What are the pros and cons of using Lego motors to drive a robot project that I have in mind ???, should I scrape (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

That still does not tell me the difference between how they are diven. For instance, can you use the 4 motor ports to drive a servo motor? If not why? Any help appreciated. Chris Rhodes (...) (26 years ago, 5-Jun-98, to lugnet.robotics.handyboard)

I've had pretty good luck getting up to around 2" by using a standard IR LED and standard IR phototransistor, modulating the IR LED in software, and looking at the analog value returned from the phototransistor like so: { int refl; led_on(); refl += (...)

1/2" is actually pretty good range for a basic reflectance sensor. try using them in the analog inputs -- you should get readings that let you read out to about 1". to get better than that, you need a modulated signal, like Pandit has described.
