use of hall effect sensors helpz? | Piclist

A discussion group for the PICMicro microcontroller. Also called the Microchip PIC, this list is dedicated to the use and abuse of this fine, simple, microcontroller. Close to topic posts are welcome, ie. general electronics.

Hi folks again, I am having some problems with settling on a method
to obtain both speed and directional monitoring of a tank-style
configured bot I am designing for a mini-sumo/line following/rc
controllable/autonomous bot platform. The way that the treads are set
up does not allow the use of optical sensors so I have been farting
around with other methods of which I have little clue. The first was
use of 'shunt' resistor feedback circuit but quickly came to realize
that would only allow for directional monitoring but not speed..(am I
wrong in that?), so then went onto the possible use of hall effect
sensors (which I have a bunch lying around and have never used), so
yesterday went into thinking about that approach, thought I had it but
soon came to realize I was running into the opposite issue (with
respect to the use of resistor feedback circuit) in that I would be
able to obtain speed monitoring functions but no directional,,,,but
late last night went to thinking a bit about a work around and
firgured that why not just add another hall sensor 'next' to the
existing proposal,, which in effect would allow both speed and
directional monitoring?? Is this a valid method to reach my functional
requirments? or is there better methods?
Could anyone point me to a good tutorial/appnotes for use of hall
sensors in similar type applications? Had a bit of a hard time finding
much of anything googling last night......

any thanks in advance for tips and tricks to obtain desired motor
control functions.....regards, jd

PS, anyone can recommend a good FREE/open source CAD package? OS no
matter but seeking unrestricted functionality, for use in hardware
design- would be nice to have movement simulation and 3D
rendering...helpz?
