Tactile and Visual Sensing
Sensing is converting a quantity that you
want to measure into a useable signal
(usually electronic).
Why do Robots need Sensors?

Light Sensor
Measures the level of light as a
number between 0% (total darkness)
and 100% (very bright).
Can differentiate light
levels reflected from
bright and dark
surfaces.

Rotation Sensor
Measures the rotation of an axle
or shaft.
The rotation sensor sends out a
series of voltage pulses. There
are 16 of these pulses per one
revolution of the Lego rotation
sensor.
These pulses are also referred to
as “ticks”, “clicks”, or “counts”.
