Shield-Bot Roaming with PING)))
A PING))) Ultrasonic Distance Sensor on a servo turret mounts on the front of the Shield-Bot,
for autonomous navigation.
The ultrasonic distance sensor detects objects up to 10 feet (3 m) away. When an obstacle is
detected, the Shield-Bot stops, sweeps the sensor from side to side, and then turns down the
clear path.
Ultrasonic distance sensors work well in strong sunlight where infrared sensors are
overwhelmed, making this a good choice for bright environments or direct sunlight.
