Sensing Basics

Requires:
Triggers

Hardware:

Switches
Encoder
LaserCan

Success Criteria

Create a Trigger that represents a sensor condition
Create a Joystick command that runs indefinitely, but stops when the Trigger is in a true condition.
Repeat with a different sensor type
Create a Trigger that performs a Command automatically when triggered

Summary

Sensing is interacting with physical objects, and changing robot behaviour based on it.
This can use a variety of sensors and methods, and will change from system to system

Sensor Information transfer

Often simple sensors like break beams or switches can tell you something very useful about the system state, which can help you set up a different, more precise sensor.

The most common application is in Homing such as a Elevator type systems. On boot, your your Encoder may not properly reflect the system state, and thus the elevator position is invalid. But, if you you have a switch at the end of travel you can use this to re-initialize your encoder, as the simple switch.
