Sumo won''t turn and moves slowly
Archiver
Posts: 46,084
Hello Gregg and Jon,
Thanx for the info. As I am new in BASIC Stamp, I've
been searching for documents on how to program a
SumoBot and I've downloaded the SumoBot Manual in
Parallax's page and read through the document. I
started out with Experiment #2: SumoBot Locomotion.
Refering to page 12, I loaded the example program
given which will test the SumoBot's motors. I was
hoping to see a correct output but the robot went the
way i mentioned earlier.
I noticed that the SumoBot in the Parallax's page is
different from mine. Mine has 4 wheels and an on-off
power switch instead of a three-position power switch.
Can I still refer the manual? I would appreciate some
guidance. [noparse]:)[/noparse]
Thanx!
