PLEN:bit

PLEN:bit is a small humanoid robot with movable arms and legs. Anyone can easily use PLEN:bit through programing and onboard sensors.

Please refer to this page about PLEN:bit https://plen.jp/plenbit/#manual

Basic usage

//Play WalkForward motion when button A pressed
//There are many other motions.
input.onButtonPressed(Button.A, function () {
    plenbit.stdMotion(plenbit.StdMotions.WalkForward)
})

Examples:

PLEN:bit Basic

plenbit.servoInitialSet()
basic.showIcon(IconNames.Happy)

basic.forever(function () {
    plenbit.eyeLed(plenbit.LedOnOff.On)
    basic.pause(100)
    plenbit.eyeLed(plenbit.LedOnOff.Off)
    basic.pause(100)
})

input.onButtonPressed(Button.A, function () {
    plenbit.stdMotion(plenbit.StdMotions.WalkForward)
})
input.onButtonPressed(Button.B, function () {
    plenbit.stdMotion(plenbit.StdMotions.ArmPataPata)

    plenbit.stdMotion(plenbit.StdMotions.WalkForward)
})
// Type B

    plenbit.walk(plenbit.WalkMode.Move)
    plenbit.walk(plenbit.WalkMode.Move)
    plenbit.walk(plenbit.WalkMode.Move)
    plenbit.walk(plenbit.WalkMode.Stop)

basic.forever(function () {
    if (input.acceleration(Dimension.Z) < -512) {
        basic.showIcon(IconNames.Sad)
        plenbit.stdMotion(plenbit.StdMotions.ArmPataPata)
    } else {
        basic.showIcon(IconNames.Happy)
    }
})

Dodge the wall

basic.forever(function () {
    if (plenbit.checkDistane(plenbit.LedLr.BButtonSide, 600)) {
        basic.showIcon(IconNames.Sad)
        for (let index = 0; index < 3; index++) {
            plenbit.stdMotion(plenbit.StdMotions.WalkRTurn)
        }
        basic.showIcon(IconNames.Happy)
    } else {
        plenbit.stdMotion(plenbit.StdMotions.WalkForward)
    }
})

Dodge the wall 2

basic.forever(function () {
    if (plenbit.checkDistane(plenbit.LedLr.BButtonSide, 600)) {
        plenbit.walk(plenbit.WalkMode.Stop)
        basic.showIcon(IconNames.Sad)
        for (let index = 0; index < 3; index++) {
            plenbit.stdMotion(plenbit.StdMotions.WalkRTurn)
        }
        basic.showIcon(IconNames.Happy)
    } else {
        plenbit.walk(plenbit.WalkMode.Move)
    }
})

GO NORTH

let direction = 0
basic.forever(function () {
    direction = plenbit.direction()
    if (direction <= 20 || direction >= 340) {
        basic.showArrow(ArrowNames.North)
        plenbit.stdMotion(plenbit.StdMotions.WalkForward)
    } else if (direction > 20 && direction <= 180) {
        basic.showArrow(ArrowNames.East)
        plenbit.stdMotion(plenbit.StdMotions.WalkLTurn)
    } else if (direction > 180 && direction < 340) {
        basic.showArrow(ArrowNames.West)
        plenbit.stdMotion(plenbit.StdMotions.WalkRTurn)
    }
})

Let’s make a motion!

plenbit.servoInitialSet()
basic.showIcon(IconNames.Happy)

input.onButtonPressed(Button.A, function () {
    R_Punch()
})
function R_Punch () {
    plenbit.setAngle([0, 0, 0, 0, -900, 0, 0, 0], 300)
    plenbit.setAngle([0, 0, 0, 0, 0, 0, 0, 0], 300)
}
input.onButtonPressed(Button.B, function () {
    L_Punch()
})
function L_Punch () {
    plenbit.setAngle([900, 0, 0, 0, 0, 0, 0, 0], 300)
    plenbit.setAngle([0, 0, 0, 0, 0, 0, 0, 0], 300)
}

Remote control

Requires two micro:bits

radio.setGroup(0)
basic.showIcon(IconNames.Happy)

input.onButtonPressed(Button.A, function () {
    radio.sendString("A")
})
input.onButtonPressed(Button.AB, function () {
    radio.sendString("C")
})
radio.onReceivedString(function (receivedString) {
    if (receivedString == "A") {
        plenbit.stdMotion(plenbit.StdMotions.WalkForward)
    } else if (receivedString == "B") {
        plenbit.stdMotion(plenbit.StdMotions.WalkRTurn)
    } else if (receivedString == "C") {
        plenbit.stdMotion(plenbit.StdMotions.HighFive)
    }
})
input.onButtonPressed(Button.B, function () {
    radio.sendString("B")
})

let Adjust = 20
basic.showIcon(IconNames.SmallDiamond)
basic.forever(function () {
    dis = plenbit.sensorLR(plenbit.LedLr.BButtonSide)
    dis = Math.map(dis, 0, 1023, 0, 330 - Adjust)
    dis = Math.map(dis, 60, 220, 50, 4)
    serial.writeValue("CM", dis)
    if (dis <= 6) {
        plenbit.stdMotion(plenbit.StdMotions.ArmPataPata)
    }
    basic.pause(50)
})

Servo Control

basic.showIcon(IconNames.Happy)

    plenbit.servoWrite(11, 34)
})

Sensor watching

basic.forever(function () {
    serial.writeValue("mic", plenbit.sensorLR(plenbit.LedLr.AButtonSide))
    serial.writeValue("dis", plenbit.sensorLR(plenbit.LedLr.BButtonSide))
})

Servo Adjust

/**
 * How to use
 * 1.Push A to start correction
 * 2.Push A or B to move each servo
 * 3.Push A+B to switch to next servo
 * 4.Loop
 * 5.Ends when smile is displayed
 * 6.Reset, then Push B to walk
 * If PLEN does not fall over, setting is complete
 */
let loop = false
let servoNum = 0
let adjNum = 0
plenbit.servoInitialSet()
basic.showIcon(IconNames.Happy)
basic.forever(function () {
    if (input.buttonIsPressed(Button.A)) {
        servoAdjust()
    } else if (input.buttonIsPressed(Button.B)) {
        plenbit.stdMotion(plenbit.StdMotions.WalkForward)
    } else if (input.buttonIsPressed(Button.AB)) {
        plenbit.resetPosition()
        basic.pause(1000)
    }
})
function servoAdjust () {
    adjNum = 0
    servoNum = 0
    basic.showNumber(servoNum)
    loop = true
