Touch Sensor
The Touch Sensor is an analogue sensor that can detect when the
sensor’s red button has been pressed and when it is released. That
means the Touch Sensor can be programmed to action using three
conditions – pressed, released, or bumped (both pressed and released).
Using input from the Touch Sensor, a robot can be programmed to
see the world as a blind person might, reaching a hand out and
responding when it touches something (pressed).
You might build a robot with a Touch Sensor pressed against the
surface beneath it. You might then program the robot to respond
(Stop!) when your robot is about to drive off the edge of a table
(when the sensor is released).
A fighting robot might be programmed to keep pushing forward
against its challenger until the challenger retreats. That pair of
actions – pressed, then released – would constitute bumped.
