How well do the Polaroid sensors everyone's using work? Do they require much external circuitry or any modifications to the handy board? I'm interested in them since I'm finally managing to get a nice working robot going... (Yeah everyone, I (...) (29 years ago, 29-Apr-96, to lugnet.robotics.handyboard)

| | excessive motor current?
|
|
I just managed to convert a Cat D10 toy into a robot. In doing so, I've converted the power source for its motors from Alkaline to NiCads. One thing I've noticed is that the NiCads make the robot seem A LOT more powerful. I measured the current (...) (29 years ago, 29-Apr-96, to lugnet.robotics.handyboard)

Hi Jeff, The Polaroid sensors work pretty darn well. I've been able to get 1" resolution from 8" to 130"++ (reportedly they work to 35 ft - my room's not big enough to try this out).

(...) Where does it get it's power from? The handy board? I just might go out and buy one of these, since I'm getting tired of my robot smashing into walls! :-) (29 years ago, 29-Apr-96, to lugnet.robotics.handyboard)

(...) Ahh, ok, that's pretty easy for me... Did you mount your array on a servo or anything? Are the transmitter and receiver both part of one module? (29 years ago, 30-Apr-96, to lugnet.robotics.handyboard)

You mean besides making it 'crawl'? In my robotics class were were programming autominus vehicle equipped with a servo mounted sonar on the front.

My new robot has a dire need for a way to keep from crashing into things all the time, and sonar would seem to be a nice (...) (29 years ago, 1-May-96, to lugnet.robotics.handyboard)
