Motors#

Introduction#

The Motion category includes blocks that control motors and motor groups in a VEX IQ (2nd generation) robot. These blocks let you spin motors forward or in reverse, move to specific positions, set and read encoder values, adjust speed, torque, or timeout settings.

Below is a list of available blocks:

Actions – Spin motors continuously, to a position, or stop them.

  • spin – Spins the selected motor or motor group indefinitely.

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

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

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

Settings – Configure motor speed, position, stopping mode, torque, and timeouts.

Values – Read motor motion status, position, velocity, and current draw.

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

  • motor velocity – Returns the motor’s current velocity in % or rpm.

  • motor current – Returns the current (in amps) drawn by the motor.

Actions#

spin#

The spin block spins a selected motor or motor group in a specified direction using the current motor velocity.
