Sensors

Your robot can have as many or more senses than you have, or it can wear blinders and focus entirely on a small trickle of data from a rudimentary sensorium. The ultimate deciding factor lies in your expectations for each of the robot projects that you design.

Light Sensors

If you look at insects closely, they have fascinating, multifaceted compound eyes. The world must look interesting to them!

But look a little more closely, and you also see some simple eyes, which resemble little black dots. OK, now back up a little; you’re making that bug nervous. The difference between simple and compound eyes lies in the number of lenses involved, and not in the inner complexity of the underlying photoreceptors and neural systems. Because the simple ...
