I am using the GP2D02 which is also identical to the GP2D05 except that on the GP2D05 you can manually set the threshole using the built-in trimpot. I am using Barry Brouillet driver for interfacing to the Handyboard/w expansion board and it works (...) (27 years ago, 27-Oct-99, to lugnet.robotics.handyboard)

I have an old 486 laptop and a few motors and sensors lying around...Does anyone know of a DSP board or some other device I could use to interface the motors and sensors to the laptop for real- time data aquistion? (I already have my handyboard (...) (27 years ago, 27-Oct-99, to lugnet.robotics.handyboard)

If a motor stalls, it draws a lot of current (compared to normal operation). You can measure that quite easilyusing dedicated chip, or by measuring the voltage over a small resistor in series with the motor: if more current is draw, the voltage drop (...)

Shaft encoders are hard to beat. If the wheels are commanded to turn and aren't, that's a good indication that something is screwy. Plus, if you're doing dead reckoning, you need them anyway so they are already there! Gary Livick (...) (27 years ago, 27-Oct-99, to lugnet.robotics.handyboard)

Hi all, I'm working on a dead reckoning 'bot. I'm not really interested in what the wheels are doing unless they're stalled. Anyone know any good tricks for monitoring the motor current, or should I go with shaft encoders anyway? Thanks! Paul (27 years ago, 27-Oct-99, to lugnet.robotics.handyboard)
