I am also designing a similar car or truck, my idea is use a rotation sensor
and worm gear to rack and pinion, then control it keeping straight base on

Hi,
I’m trying to get my robot moving straight, but it doesn’t work. My robot is
configured for differential steering and I have shaft encoders installed on
each one for feedback. The encoders are working with the encoder library
from the Handy Board Page. Does anybody have an IC-Code to get a robot
moving straight?
Or has anyone  modified the proportional-integral-control (with the shaft
encoders connected to PA0 and PA7) out of the book “Mobile Robots:
Inspiration to Implantation” modified for use with the HB?

Any help would be really appreciated.
Please help me! Thanks,

Jan

Hi Zhengrong, I think it is possible. Your Handyboard has to give a pwm signal to your gyroscope. The gyroscope lengthens or shortens this pwm and gives it back to the Handyboard. I haven’t ever seen drivers for a gyroscope, so you’ll have to write (...) (23 years ago, 3-Jul-01, to lugnet.robotics.handyboard)
