microbit-robot
This extension contains blocks for most 2 wheeled robots available for the micro:bit and a web simulator. This library is compatible with micro:bit V2 and V1. However, the code space in V1 is limited and you may need to remove some features to fit your program.
The library is still in beta and is subject to changes.
The firmware is designed for popular rover robots found in the micro:bit ecosystem (and more can be added):
The following features are found often those robots:
The simulator will load automatically in MakeCode once you use a robot block. It is designed to help programming this kind of robot.
The extension uses the 5x5 screen to show the state of the robot (you can turn off this behavior see configuration). This is particularly useful to debug your robot program.
At the start of any robot program, you need add the block to select the robot model you will be using.
This should be done before using any other blocks.
robot.elecfreaksCuteBot.start()This is the only code that is specific to the robot you are using. The rest of the blocks are the same for all robots.
input.onButtonPressed(Button.A, () => {
robot.motorRun(0, 100)
})The move block takes a steering and speedparameters.
Thesteeringcontrols how much “turn”,speed controls the throttle on the motors.
input.onButtonPressed(Button.B, () => {
robot.motorStop()
})input.onButtonPressed(Button.B, () => {
robot.armOpen(0, 50)
})input.onButtonPressed(Button.A, function () {
robot.setColor(0xff0000)
})input.onButtonPressed(Button.A, function () {
robot.playTone(262, music.beat(BeatFraction.Whole))
})let dist = 0
robot.onObstacleDistanceChanged(function () {
dist = robot.obstacleDistance()
})let left = false
robot.onLineDetected(function () {
left = robot.detectLine(RobotLineDetector.Left)
})robot.setAssist(RobotAssist.Display, false)robot.setMotorDrift(10)robot.setAssist(RobotAssist.LineFollowing, false)robot.setAssist(RobotAssist.Speed, false)Use micro:code to remote control a robot using this library.
