  • spin motor for - Spins a motor or motor group for a specific distance in degrees or turns.

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

  • stop motor - Stops a specific motor or motor group from spinning.

• Settings

  • set motor velocity - Sets the speed of a motor or motor group 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 or motor group.

• Values

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

  • motor is spinning? - Returns a Boolean indicating whether the motor is currently spinning.

  • motor velocity - Returns the motor’s current velocity in %.

Sensing - Utilize the robot’s various sensors.

Settings

set motor position

The set motor position block sets a specific position value to a motor or motor group, which updates the encoder reading.

set [IntakeMotor v] position to [0] [degrees v]

set [CatapultGroup v] position to [0] [degrees v]

set motor velocity

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