 "Landmine
Sweeper" is a fantasy name for a robot that simply
detects black bricks on flat lighter surfaces, collects and stores
them
in its large compartment.
This robot is
described in my book
"Creating Cool MINDSTORMS NXT Robots",
that includes building and programming instructions.
It
moves around as a differential drive robot, with a Tribot-like
caster wheel.
The grabber mechanism is driven by a motor, that closes the rubber-fingered claw and rises it to stock the
"mine";
then opens the claw and brings the arm down again.
The light sensor is used to detect black objects on the surface,
while the ultrasonic sensor detects if robot is going to fall down
from the table,
activating a backup procedure. |
