moveall()

The function sets the servo motors of the humanoid hip, foot and hand to the specified angles at the specified speed.

Syntax: moveall(time = 1000, servo angles = [90,90,90,90,90,90])

setpickangle()

The function sets the angles of the pick action of the pick and place robot to a specified value.

Syntax: setpickangle(angle = 40)

math.ceil()

The function is used to return the ceiling value of a number, which means it is used to round a number up to the nearest integer that is greater than the number itself.

Syntax: math.ceil(x)

roboticArm.moveincircleanticlockcise()

This function creates a anti-clockwise circle trajectory in the Y plane for a robotic arm, given the center position in the X and Z axes, and the radius of the circle.

Syntax: roboticArm.moveincircleanticlockcise(XPOS = 0, ZPOS = 80, RADIUS = 50, YPOS = 180, TIME = 4000)

setlinefollowerparameter()

This function’s parameters match the Quarky board’s regular line following settings, defining motor speeds: F for forward on white, and T1 and T2 for gentle turning along the black line.

Syntax: setlinefollowerparameter(F = 35, T1 = 40, T2 = 10)

isexpression()

This function is used to check whether the expression of the face number specified in the argument is equal to the specified expression. Like is the face 1 happy?

Syntax: isexpression(face = 1, expression = “happy”)

changeeffect()

The function changes the specified effect on its sprite by the specified amount. There are seven different effects to choose from: colour, fisheye, whirl, pixelate, mosaic, brightness, and ghost.

Syntax: changeeffect(effect_name = “COLOR”, effect_value = 25)

setvolume()

The function holds a sprite’s or the Stage’s volume. This block can be displayed as a Stage monitor.

Syntax: setvolume()

loudness()

The function reports how loud the noise that a microphone receives, on a scale of 0 to 100.

Syntax: loudness()

showtext()

The function sets the RGB LED display matrix to display the specified character.

Syntax: showtext(character = “A”, color = [0, 0 , 0])

readanalogsensor()

The function returns the analog reading of the sensor connected to the specified analog pin of the Quarky. The value varies between 0 to 4095.

Syntax: readanalogsensor(analog_pin = “A1”)

moveservo()

The function sets the servo motor connected to the specified servo pin to the specified angle.

Syntax: moveservo(servo_pin = “Servo 1”, angle = 90)

landmark()

The function reports the landmark identified in the image on analysis.

Syntax: landmark()

setgripperangle()

The function sets the current Quarky Gripper Robot’s gripper servo motor angle to the specified value.

Syntax: setgripperangle(angle = 90)

resetoscillationparameters()

The function resets the oscillator parameter for all the servo motors.

Syntax: resetoscillationparameters()

gassensorstatus()

The function reports the state of the Gas sensor connected to the selected pin. The block returns 1 when the analog reading of the sensor is greater than the threshold value set by the user. Else it reports 0.

Syntax: gassensorstatus(pin = “A1”)

movelimb()

The function sets the selected servo motor angle to the specified angle in the specified time. This creates a smooth motion for the servo motor from the current angle to the specified angle.

Syntax: movelimb(servo name = “RHip”, angle = 90, time = 1000)

setplaceangle()

The function sets the angles of the place action of the pick and place robot to a specified value.

Syntax: setplaceangle(angle = 90)

roboticArm.moveinarc()

This function is used to control an end–effector of the robotic arm to move in an arc.

Syntax: roboticArm.moveinarc(XPOS = 0, ZPOS = 80, RADIUS = 50, START = 90, END = 270, YPOS = 180, TIME = 4000)

dolinefollowinguntilcheckpointdetect()

This function enables the robot to follow a line continuously until it detects a checkpoint (both IR sensors on black); it stops only at the checkpoint or with a reset.

Syntax: dolinefollowinguntilcheckpointdetect(next_checkpoint = 1)

x()

This function returns the x position of the face detected. You can specify the face for which the value is needed. The position is mapped with the stage coordinates.

Syntax: x(face = 1)

setdirection()

The function points its sprite in the specified direction; this rotates the sprite.

Syntax: setdirection(angle = 15)

seteffect()

The function sets the specified effect on its sprite to the specified amount. There are seven different effects to choose from: color, fisheye, whirl, pixelate, mosaic, brightness, and ghost.

Syntax: seteffect(effect_name = “COLOR”, effect_value = 25)

timer()

The function reports the time lapsed since the PictoBlox is launched and increases gradually; every second it will have increased by 1.

Syntax: timer()

showscrollingtext()

The function runs the specified text message on the RGB LED of Quarky. You can also set the speed and the color of the text.

Syntax: showscrollingtext(message = “Hi I am Quarky”, speed = 1, color = [0, 0 , 0])

imagedescription()

The function reports the image description identified in the image on analysis – a Human-readable sentence that describes the contents of the image.

Syntax: imagedescription()
