It can be very simple to make robots- and given the right processor, very
simple to program them. What is tricky is learning the ground rules, like how
best to make something hold a motor still or lock a battery in place.
Robotics is fun and addictive and once you have made one machine crawl
across the floor according to your rules, from dead motors and scraps of metal
and plastic, you will be thinking of larger and better projects from then on.
