Hi, I am trying to built my first robot and I have a question. I tried to make my robot "to be" move straight. (I am using the servos routines from the HB web page.) When I start the servos the robot just goes in circles not straight. I try flipping (...) (27 years ago, 30-Sep-97, to lugnet.robotics.handyboard)

I think you're talking about a game called Crossfire (it was very popular about 6 years ago), and there are still quite a few floating around (though I don't think they make it anymore), you should try some garage sales. BTW, the reason I know this (...) (27 years ago, 30-Sep-97, to lugnet.robotics.handyboard)

Hello, I'm most likely going to use the Handy Board for a robotics project I'm working on, but I have one concern. I don't know if 32K is enough memory for my control program. We are building several small robots to simulate under-water mine (...) (27 years ago, 29-Sep-97, to lugnet.robotics.handyboard)

Mar, I've never seen a caster as small as you describe, but I have seen something that might work. I use a "captured ball" bearing instead of a caster on my robot, and it works really well (no swivelling needed to change direction). I got these at a (...)

does anyone know where to get a small caster? The smallest one I've found is one with a 1.25 inch wheel. I want a really small one like 3/8 inch load hight. I know that's kinda small but otherwise, I'll settle for the smallest I can get my hands on. (...) (27 years ago, 26-Sep-97, to lugnet.robotics.handyboard)

You can attach a servo to either Port A Bit 7 (Input 9) or Port A Bit 5 (TO3 (under the lcd display)) Which ever port you use you will need the code at the handyboard home page under software and dual servo control to make it work.
