The potentiometer on the ROBOTICS module allows you
to control the speed of the two drive motors. When the
potentiometer is in the middle position (viewed from above,
so that the DIP switch designation is easily legible) both drive
motors turn at the same speed propelling the Mini Bot straight
ahead. Turning the potentiometer to the left causes it to curve
to the left while moving forwards. Turning the potentiometer to
the right causes it to curve to the right while moving forwards.
Hindrance Detector
DIP switch setting:
The Mini Bot hindrance detector is equipped with two
mini-switches on the two bumpers which serve as sensors.
After starting the program the Mini Bot moves straight
ahead. It continues this until one of the bumpers touches
an obstacle.
If, for example, the left bumper, as seen when facing in
the direction of motion, hits against a hindrance, it moves
back a short distance. During this maneuver it also deviates
by turning to the right, and then continues to move forwards. This
deviating motion helps the Mini Bot to move around an obstacle or out
of a corner.
You can set the distance for this deviation on the potentiometer. When
the potentiometer is set to the middle position, the deviation is identical
in both directions. Turning the potentiometer to the left (viewed from
above, so that the DIP switch designation is easily legible) increases the
deviation to the left accordingly and reduces the deviation to the right by
an equivalent amount.
