Ball Sensor
Ball sensor is the most imoportant sensor to your robot. It provides you with information about the relative angle from your robot to the ball, as well as it's distance.
The angle goes from -180 to 180, relative to your robot's orientation.
The distance, goes from 0 to the limit of the sensor (around 1 meter). If this limit is reached,
both angle and distance returns 0.
Angle measurements are in degrees and distance measurements are in meters.
RobotBasic ID
RobotBasic class provides you with one SensorBall installed, its ID is BALL.
Value Returned
Ball Sensor returns two values, the first being the ball angle, and the seccond with the ball distance.
Sensor ballFinder = getSensor("BALL");
float angleToBall = ballFinder.readValue(0);
float distToBall = ballFinder.readValue(1);
Limits and Noise
In case the ball is too far from the robot (usually > 1 meter), the output will be 0 for both
angle and distance.
Those values are also subjected to random noises.
