I am very new to this so please be patient with me.
I am pretty familiar with most electronics, and am in the
process of designing a robot which will serve a few
I am currently building a PIC programmer,
bastardized version of one of Bojan's. I am going to us a
16F877 for my main controller, and one more to control a
few peripherals, addressed by the primary controller as
This robot is self charging, self
navigate complex room interiors. This robot also must
utilize voice recognition, though it will be limited to
very few commands.
For locomotion, I am using 2 small TEAC
steppers, which I canabalized from some very archaic
floppy drives. I like to do things cheaply. I also like
the fact that if one of my brakes fail, my MCU can sense
this and revert to motor braking. Safety is job one.
This is one of my largest questions, though... what are
disadvantages to these compared to DC's or servos? I am
only using them for locomotion, and not braking, which
will be handled differently. But are there any advantages
to steppers in this application? Since the steppers are
driving the wheels directly, the friction environment will
negate the advantage of stepping, in my opinion.
All opinions are considered and appreciated. Thanx.
