The problem with IR is that it tends to get everywhere, reflecting off of surfaces etc, so it's hard to triangulate. May I suggest a related but different approach. Make your beacons out of hybrid IR/sonar transmitters. The beacons will periodically (...) (22 years ago, 1-May-02, to lugnet.robotics.handyboard)

I am beginning to design a handyboard robot that, for starters, can navigate around a room. The idea is that it will travel to objects whose coordinates within the room are predetermined and interact with them. I plan to do this by triangulating the (...)

I believe that some research work in autonomous vacuum cleaners in the late 90's determined that a random walk over the course of a few hours was just as good as a methodical path. I'll see if I can dig up the reference... (...) --- Karl ___...___ (...) (22 years ago, 24-Apr-02, to lugnet.robotics.handyboard)

HI, I am currently working on a handyboard based dust buster bot(goofy, I know) and have been trying to design an algorithm where my vehicle could methodically cover all the area in a given room, starting by following along the perimeter walls and (...)

I am working on a program that will envolve several different files. So I have been trying to figure out how to creat a (.lis), file that could be used to load all the files together; lessing the pain on loading them one, by one. Anyway, I can't (...)

| | Re: Overcharged NiCd Batteries?
|

Aha, I know nothing about Handyboards, only about NiCads. I don't see why you need a larger power supply to charge slightly larger cells. Your handyboard is probably only drawing about 75 to 100 mAh to charge at 50 mAh, so a bigger power supply (...) (22 years ago, 10-Apr-02, to lugnet.robotics.handyboard)

I'm sorry, I didn't explain myself well enough. I meant to say that I used the 500mA 12V power supply (block AC to DC transformer) by connecting it to the handyboard. From the specifications, the handyboard is supposed to be able to charge 800mAh (...) (22 years ago, 9-Apr-02, to lugnet.robotics.handyboard)

Jeremy, You hooked it straight to a 12V power supply? That's kind of a brutal way to charge NiCad's. Who knows what that's going to do. If it's regulated at 500mA, then it should take just a little over two hours to charge a 1000mAh pack, which is a (...) (22 years ago, 9-Apr-02, to lugnet.robotics.handyboard)
