Chapter 15. Surveillance Robot


The Evil Genius Lair is patrolled by a security robot. This robot wanders around the lair in a random manner, occasionally tripping-up minions. It also serves the more practical, but less amusing role of monitoring the lair when the Evil Genius is asleep at night.

The robot is equipped with a passive infra-red sensor and a loud alarm. It will move around, occasionally stopping and monitoring the area in front of it with its PIR movement sensor. If it then detects any movement, it sounds the alarm.

This is another project based on an Arduino microcontroller board. It uses modified low cost electric screwdrivers to provide powerful geared motors to drive it along and an infrared distance sensor to prevent collisions. Although this is not always successful.
