This library provides blocks to control the Gigglebot, its motors, neopixels, sensors and servos. For more information: https://www.gigglebot.io/pages/program-the-gigglebot-robot
To drive forward and back for 2 seconds each:
input.onButtonPressed(Button.A, () => {
gigglebot.driveMillisec(gigglebotWhichDriveDirection.Forward, 2000)
gigglebot.driveMillisec(gigglebotWhichDriveDirection.Backward, 2000)
})
Turning will have the GiggleBot make a sharp turn around one of its wheel. This block will get the GiggleBot to turn right for a full second.
gigglebot.turnMillisec(gigglebotWhichTurnDirection.Right, 1000)
Using the spin block is useful when drawing because the turns will be around the pen, instead of around a wheel. That way, you can get good corners when drawing.
gigglebot.spinMillisec(gigglebotWhichTurnDirection.Left, 1000)
With steering you control how much turning each wheel can do. In this example, the robot will turn towards the right, doing a curve around an object. The first number is percent-based. With a value of 0, the robot will not turn at all. With a value of 100, you will get the same behavior as the turn block.
gigglebot.steerMillisec(20, gigglebotWhichTurnDirection.Right, 1000)
You can have blocks to drive, turn, spin, and steer, which are not time limited. That way, you can decide when to interrupt the GiggleBot. Maybe it gets dark, or there's an obstacle ahead.
gigglebot.driveStraight(gigglebotWhichDriveDirection.Forward)
gigglebot.turn(gigglebotWhichTurnDirection.Right)
gigglebot.gigglebotSpin(gigglebotWhichTurnDirection.Right)
gigglebot.steer(20, gigglebotWhichTurnDirection.Right)
When using blocks that do not have a time limit to them, you will need to stop the robot yourself.
gigglebot.stop()
You can set the motors to five different speeds, from slowest to fastest. You can either set one motor, or both at the same time. Be careful, if you set the motors to different speeds, it will not drive straight.
gigglebot.setSpeed(gigglebotWhichMotor.Both, gigglebotWhichSpeed.Slowest)
The GiggleBot comes with two line sensors that allows it to follow either a thick line or a thin line. The thick line is thick enough that both sensors will attempt to be over the line, while the thin line is thin enough to fit between the two sensors and each sensor will attempt to avoid the line.
input.onButtonPressed(Button.A, function () {
gigglebot.lineFollow(gigglebotLineType.Thick)
})
You can also access the line sensors values directly by using the blocks under the "more..." section. This allows you to write a line follower logic that is tailored to your specific needs.
basic.showNumber(gigglebot.lineReadSensor(gigglebotWhichTurnDirection.Right))
You can use the following code as the basis for your own line follower. First, detect what are good values for detecting your line, then code the appropriate movements.
basic.forever(() => {
if (gigglebot.lineReadSensor(gigglebotWhichTurnDirection.Right) < 200) {
basic.showIcon(IconNames.Yes)
} else {
basic.showIcon(IconNames.Asleep)
}
})
The GiggleBot comes with two light sensors that allows it to follow a spotlight, a little bit like a cat would. Shining a flashlight onto one eye will get the GiggleBot to turn in that direction. The robot will go straight if the two sides receive similar lighting conditions.
input.onButtonPressed(Button.A, function () {
gigglebot.lightFollow()
})
input.onButtonPressed(Button.B, function () {
gigglebot.stop()
})
You can also read the light sensors values directly in order to implement a different behaviour, like having the GiggleBot fall asleep when it gets dark, and wake up when there's light. The light sensor reading block can be found under the "more..." section.
basic.forever(() => {
if (gigglebot.lightReadSensor(gigglebotWhichTurnDirection.Right) < 200) {
basic.showIcon(IconNames.Asleep)
} else {
basic.showIcon(IconNames.Happy)
}
})
The GiggleBot comes with two servo connectors. What will you do with them? You can control them one by one, both together (in synchro), or both mirrored, depending on how they are positioned on the robot.
gigglebot.servoMove(gigglebotServoAction.Right, 90)
if (gigglebot.distanceSensorTestForObstacle(gigglebotInequality.Farther, 100)) {
gigglebot.driveStraight(gigglebotWhichDriveDirection.Forward)
} else {
gigglebot.stop()
}
You can add a distance sensor to the robot. This distance sensor is not ultrasonic, but laser-based.
The smile Neopixels will give feedback on the distance sensor readings.
basic.forever(function () {
lights.smileShowGraph(gigglebot.distanceSensorReadRangeContinuous(), 300)
}
})
