 | | POLAROID 6500 INCONSISTENT

|
Hello all, I have a Polaroid 6500 connected to the HB in the standard and well documented fashion. It is working and delivers values that approximate the correct distances. However, it is somewhat inconsistent. For example it will return a lower (...) (25 years ago, 25-Jun-99, to lugnet.robotics.handyboard)

I'm having the same problem with my expansion board. When I type sonar_display(); the numbers start flashing on the LCD. The numbers are changing rapidly and appear to be both negative and positive. The numbers seem to be random as well. I made sure (...) (25 years ago, 24-Jun-99, to lugnet.robotics.handyboard)

It sounds like you are running open loop. If you use the wheel encoders as feedback devices to close the loop, then you can use the motor control function in your program as a variable to adjust motor control current via PWM to match the command (...)

A group of us are building the HB and we are at the serial interface building stage. When we perform the test on the serial interface to get +9 or +10 volts, we are all getting values of up to +8.5 only. Is there a problem or is this normal? Thanks (...)

What are the meanings of the various runtime errors? Thus far I have gotten 3 and 4, but I am curious as to what the rest are as well. =) Andrea (25 years ago, 22-Jun-99, to lugnet.robotics.handyboard)
