Sensors

Real-time values that comes from the robot's sensors. For example, "if accelerometer z-axis > 3G's, then set LED's to green."


Accelerometer

Motion acceleration along a given axis, in g's.

getAcceleration().x is the left-to-right acceleration, from -8 to 8 g's.

getAcceleration().y is the forward-to-back acceleration, from of -8 to 8 g's.

getAcceleration().z is the up-and-down acceleration, from -8 to 8 g's.

Math.sqrt((getAcceleration().x ** 2) + (getAcceleration().y ** 2) + (getAcceleration().z ** 2)) is the combined vector acceleration of all 3 axes, from 0 to 14 g's.

getVerticalAcceleration is the upward or downward acceleration regardless of the robot's orientation, from -8 to 8 g's.

Orientation

The tilt angle along a given axis measured by the Gyroscope, in degrees.

getOrientation().pitch is the forward or backward tilt angle, from -180° to 180°.

getOrientation().roll is left or right tilt angle, from -90° to 90°.

getOrientation().yaw is the spin (twist) angle, from -180° to 180°.

5 orientation


Gyroscope

The rate of rotation around a given axis, from -2,000° to 2,000° per second.

getGyroscope().pitch is the rate of forward or backward spin, from -2,000° to 2,000° per second.

getGyroscope().roll is the rate of left or right spin, from -2,000° to 2,000° per second.

getGyroscope().yaw is the rate of sideways spin, from -2,000° to 2,000° per second.

5 gyro


Velocity

The velocity along a given axis measured by the motor encoders, in centimeters per second.

getVelocity().x is the right (+) or left (-) velocity, in centimeters per second.

getVelocity().y is the forward (+) or back (-) velocity, in centimeters per second.

Math.sqrt((getVelocity().x ** 2) + (getVelocity().y ** 2)) is the combined vector velocity of both axes which will always be a positive value, in centimeters per second.

5 velocity


Location

The distance from the origin of the program start, in centimeters. This is not the distance traveled during the program, it is the offset from the origin.

getLocation().x is the right (+) or left (-) distance from the origin of the program start, in centimeters.

getLocation().y is the forward (+) or backward (-) distance from the origin of the program start, in centimeters.

Math.sqrt((getLocation().x ** 2) + (getLocation().y ** 2)) is the total distance from the origin of the program start, which will always be a positive value, in centimeters.

5 location


Distance

getDistance() is the total distance traveled in the program, in centimeters.

5 distance


Speed

getSpeed() is the current target speed of the robot, from -255 to 255, where positive is forward, negative is backward, and 0 is stopped. 5 sense speed


Heading

getHeading() is the target directional angle, in degrees. Assuming you aim the robot with the blue tail light facing you, then 0° heading is forward, 90° is right, 180° is backward, and 270° is left. 5 sense heading

5 heading diabram


Main LED

getMainLed() is the RGB color of the main LEDs, from 0 to 255 for each color channel.

getMainLed().r is the red channel, from 0 - 255.

getMainLed().g is the green channel, from 0 - 255.

getMainLed().b is the blue channel, from 0 - 255.

5 sense main led


Back LED

getBackLed() is the brightness of the back LED, from 0 to 255.

1 sense back led


Time Elapsed

5 sense time

getElapsedTime() is the amount of time that the program has run for, in seconds. For example, you could use getElapsedTime() to swap between forward and backward movements every 4s in an ocean buoy animation using:

var lastTime = 0;
var loopCount = 0;

async function startProgram() {
	setBackLed(255);
	for (var _i1 = 0; _i1 < 4; _i1++) {
		await Sound.Water.Waves.play(false);
		if ((loopCount % 2) === 1) {
			while (!(((getElapsedTime() - lastTime) >= 4))) {
				setMainLed({ r: 11, g: 255, b: 0 });
				await rawMotor(1000, 1000, 0.4);
				setMainLed({ r: 0, g: 0, b: 0 });
				await delay(0.5);
			}
			lastTime = getElapsedTime();
		} else {
			while (!(((getElapsedTime() - lastTime) >= 4))) {
				setMainLed({ r: 255, g: 41, b: 16 });
				await rawMotor(-1000, -1000, 0.4);
				setMainLed({ r: 0, g: 0, b: 0 });
				await delay(0.5);
			}
			lastTime = getElapsedTime();
		}
		loopCount = (loopCount + 1);
		await delay(0.025);
	}
}
