  • spin motor to position - Spins a motor to a set position.

  • stop motor - Stops a specific motor from spinning.

• Settings

  • set motor velocity - Sets the speed of a motor as a percentage.

  • set motor timeout - Limits how long a motor block waits before giving up if movement is blocked.

• Position

  • motor position - Returns the motor’s current rotational position in degrees or turns.

  • set motor position - Sets the encoder value of a motor.

• Values

  • motor is done? - Returns a Boolean indicating whether the motor is no longer spinning.

spin [IntakeMotor v] [intake v]

Parameters	Description
motor	The motor to spin: IntakeMotor ArmMotor
direction	The direction to spin: IntakeMotor intake outtake ArmMotor up down

Example

spin motor for

The spin motor for block spins a selected motor for a specific amount of rotation using the current motor velocity, measured in degrees or turns.

spin [IntakeMotor v] [intake v] for [90] [degrees v] ▶

Parameters	Description
motor	The motor to spin: IntakeMotor ArmMotor
direction	The direction to spin: IntakeMotor intake outtake ArmMotor up down
distance	The rotation amount, as an integer or decimal.
unit	The unit of measurement representing the distance: degrees turns
expanding arrow	By default, this is a waiting block, so the motor will finish moving before running the next block. Expand the block to say and don’t wait to make it non-waiting.

Example

cuando empezó
[Collect the preloaded Disc.]
spin [IntakeMotor v] [intake v] for [180] [degrees v] ▶

spin motor to position

The spin motor to position block spins a motor to a specific absolute position using the current motor velocity and motor position.

spin [ArmMotor v] to position [90] [degrees v] ▶

Parameters	Description
motor	The motor to spin: IntakeMotor ArmMotor
position	The target position to spin the motor to.
unit	The unit of measurement: degrees turns
expanding arrow	By default, this is a waiting block, so the motor will finish moving before running the next block. Expand the block to say and don’t wait to make it non-waiting.

Example

cuando empezó
[Raise the Arm to reach over the barrier.]
spin [ArmMotor v] to position [600] [degrees v] ▶

stop motor

The stop motor block immediately stops the selected motor.

stop [IntakeMotor v]

Parameters	Description
motor	The motor to stop: IntakeMotor ArmMotor

Example

cuando empezó
[Raise the Arm for 1 second, then stop.]
girar [ArmMotor v] [arriba v]
esperar (1) segundos
parada [ArmMotor v]

Settings

set motor velocity

The set motor velocity block sets the default spinning speed of a motor as a percentage for all subsequent Motor blocks in the project.

set [IntakeMotor v] velocity to [50] [% v]

Parameters	Description
motor	The motor to set the velocity of: IntakeMotor ArmMotor
velocity	Sets the default movement velocity from 0 to 100 as a percent.
unit	The unit that represents the velocity: %

Example

cuando empezó
[Spin the Intake Motor at 75 percent speed.]
set [IntakeMotor v] velocity to [75] [% v]
spin [IntakeMotor v] [intake v] for [180] [degrees v] ▶

set motor timeout

The set motor timeout block sets a time limit for how long a Motor block will wait to reach its target. If the robot cannot complete the movement within the set time, it will stop automatically and continue with the next block.

Establezca el tiempo de espera [ArmMotor v] en [1] segundo

Parameters	Description
motor	The motor to set the timeout of: IntakeMotor ArmMotor
time	The maximum number of seconds a Motor block will run before stopping and moving to the next block.

Example

cuando empezó
[Limit how long the Arm Motor will wait to move.]
set [ArmMotor v] timeout to [2] seconds
spin [ArmMotor v] [up v] for [3] [turns v] ▶
