	The color sensor can measure amount of ambient light, the amount of reflected light that comes back when its built-in LED is pointed at an object or it can determine the color of the light that it receives. Reflected light is measured in percentage with a low number being no light and 100 being almost all the light was reflected. When the sensor is used to detect a color you can choose black, brown, blue, green, yellow, red, white or no color.

When the sensor is used to detect a color you can choose black, brown, blue, green, yellow, red, white or no color. These colors may not match the colors on the annual challenge mat. In that case, using the reflected light mode of the sensor may be a more accurate way to detect or follow a line.

	Sensors are used to serve as the "eyes and ears" of the robot to allow it to navigate on the playing field. Both the Mindstorms EV3 set and the SPIKE Prime set contain a collection of sensors that can be plugged into sockets (called ports) on the robot's hub. Team members can write programs that use the sensors to control the turns of the robot, keep it driving relatively straight, detect collisions or pending collision with obstacles, detect colors on the playing field, follow lines, etc. Using sensors can make the difference between a robot that sometimes reaches its goal and one that ~~almost always~~ does, ~~allowing it to~~ rack up points ~~much~~ more consistently.

In other words, using sensors can help a robot rack up more points more consistently.

			The force sensor allows the robot to measure newtons of force. This could allow the robot to use a lever arm to detect that it is getting close to a wall and adjust its course. Alternatively, the sensor can used as an on-off switch to determine what part of a program should be used, or it can be used to detect a tap or a bump.
