Introducción #

Motors control how parts of a robot move. Motors can be used to raise an arm, turn a claw, spin a wheel, or move another part of a build. Two motors can work together as a drivetrain to move and turn the whole robot.

Each motor is configured in the Devices window. Depending on the build, the names of the motors and directions can change. For example, the Competition Advanced 2.0 build has a motor named ArmMotor, with directions up and down. A custom robot may use different motor names or directions.

By default, forward spins a motor counterclockwise, and reverse spins a motor clockwise. If a motor is set to reverse in the Devices window, those directions will be switched.

A VEX GO Motor showing the forward direction indicated by a plus sign and an arrow indicating it is rotating left, or counterclockwise.

A VEX GO Motor showing the reverse direction indicated by a minus sign and an arrow indicating it is rotating right, or clockwise.

There are many ways to code motors. Below is a list of all Motion blocks:

Acciones: Detener y hacer girar los motores.

spin motor — Spins a motor forward or reverse forever.
girar motor durante — Hace girar un motor durante una distancia específica.
spin motor to position — Spins a motor to a specific position.
stop motor — Stops a motor from spinning.

Ajustes: Ajuste la configuración del motor.

set motor position — Changes the motor’s current position to a new value.
set motor velocity — Tells a motor how fast to spin.
set motor stopping — Sets how a motor will stop moving: by braking, coasting, or holding.
set motor max torque — Sets how hard a motor is allowed to push while spinning.
set motor timeout — Sets how many seconds a motor will try to finish a movement.

Values — Check motor status.

motor is done — Reports whether the motor is finished moving.
motor is spinning? — Reports whether the motor is spinning.
motor position — Reports the motor’s current position.
motor velocity — Reports how fast the motor is spinning, as a percentage from -100% to 100%.
motor current — Reports how much power the motor is using from the battery, as a percentage from 0% to 100%.

Comportamiento #

motor de giro #

The spin motor stack block spins a motor forward or reverse forever. The motor will continue to spin until it is given another action, like spinning in a different direction or stopping.

girar [ArmMotor v] [arriba v]

Parámetros	Descripción
motor	The motor to spin. Choose from the motors configured in the Devices window.
dirección	The direction the motor spins. By default, the choices are forward and reverse. Direction choices can change depending on the motor’s configuration.

[Build Used: Competition Advanced 2.0]
[Raise the ArmMotor, then stop.]
girar [ArmMotor v] [arriba v]
esperar [1] segundos
parada [ArmMotor v]

motor de giro para #

The spin motor for stack block spins a motor for a specific distance. The spin is relative to the current position of the motor. The project will wait until the motor is done spinning before the next block in the stack runs.

girar [ArmMotor v] [arriba v] por [90] [grados v] ▶

Parámetros	Descripción
motor	The motor to spin. Choose from the motors configured in the Devices window.
dirección	The direction the motor spins. By default, the choices are forward and reverse. Direction choices can change depending on the motor’s configuration.
distancia	The distance the motor spins. Degrees use integers. Turns can use integers or decimals.
unidad	The distance unit: degrees or turns.
and don’t wait	Select the arrow ( ▶ ) to expand the block to say and don’t wait, so the next block in the stack will run right away.

girar [ArmMotor v] [abajo v] por [180] [grados v] ▶

motor de giro para posicionar #

The spin motor to position stack block spins a motor to a specific position.

A motor’s position is how far it has spun, measured in degrees or turns. One turn is equal to 360 degrees. At the beginning of a project, the motor position is set to 0 degrees. The motor position can also be set using the set motor position block.

Position values are absolute. This means the direction of the spin depends on the motor’s current position.

Ajustes #

establecer la posición del motor #

A motor’s position is how far it has spun, measured in degrees or turns. One turn is equal to 360 degrees. The set motor position stack block changes the motor’s current position to a new value.

For example, if a motor has spun to 180 degrees, setting the position to 0 degrees will reset that position from 180 to 0 degrees. Then the motor can spin to positions based on that new value.

Establezca la posición [ArmMotor v] en (0) [grados v]

Parámetros	Descripción
motor	The motor to set the position for. Choose from the motors configured in the Devices window.
posición	The position value to set for the motor. Degrees use integers. Turns can use integers or decimals.
unidad	The position unit: degrees or turns.

Ejemplo

esperar [1] segundos
girar [ArmMotor v] a la posición [0] [grados v] ▶

establecer la velocidad del motor #

The set motor velocity stack block tells a motor how fast to spin. A higher percentage makes the motor spin faster and a lower percentage makes the motor spin slower.

Every project begins with each motor spinning at 50% velocity by default.

Note: A higher velocity makes the motor spin faster, but it may be less precise. A lower velocity makes the motor spin slower, but it can be more precise.

set [ArmMotor v] velocity to [50] %

Parámetros	Descripción
motor	The motor to set the velocity for. Choose from the motors configured in the Devices window.
velocidad	The velocity to spin with from 0% to 100%.

Parámetros	Descripción
motor	The motor to set the stopping behavior for. Choose from the motors configured in the Devices window.
comportamiento de detención	How the motor will stop: brake — Stops immediately. coast — Slows to a stop. hold — Stops immediately and holds the motor’s position.

Parámetros

Descripción

motor

The motor to set the stopping behavior for. Choose from the motors configured in the Devices window.

comportamiento de detención

How the motor will stop:

brake — Stops immediately.
coast — Slows to a stop.
hold — Stops immediately and holds the motor’s position.

For example, if a Competition Advanced 2.0 build is used and ArmMotor is set to hold, the motor will hold the arm at its current position until another arm movement happens. This means the motor will work against gravity to keep the arm in the air if the motor was stopped with the arm raised.

If this block is not used, the motor will use brake when stopping.

Ejemplo

esperar [1] segundos
parada [ArmMotor v]

establecer el par máximo del motor #

Torque is a turning force. It shows how hard a motor can push or pull when it spins.

The set motor max torque stack block sets the most torque a motor is allowed to use.

A higher percentage lets the motor push harder, like when lifting a heavy object. A lower percentage limits how hard the motor can push. This can help protect the robot if the motor gets stuck or reaches the end of how far it can move.

Every project begins with each motor’s torque at 50% by default.

set [ArmMotor v] max torque to (50)%

Parámetros	Descripción
motor	The motor to set the max torque for. Choose from the motors configured in the Devices window.
esfuerzo de torsión	The max torque the motor can use from 0% to 100%.

[Move the ArmMotor at different torques.]
girar [ArmMotor v] [arriba v] por [180] [grados v] ▶
esperar [1] segundos
[Move with less torque.]
Establezca el par [ArmMotor v] en [20]%
girar [ArmMotor v] [abajo v] por [180] [grados v] ▶
esperar [1] segundos
[Move with maximum torque.]
Establezca el par [ArmMotor v] en [100]%
girar [ArmMotor v] [arriba v] por [180] [grados v] ▶

establecer el tiempo de espera del motor #

The set motor timeout stack block sets how many seconds a motor will try to finish a movement. If the motor cannot finish in that time, it will stop trying and move on to the next block in the stack. This keeps the motor from getting stuck on a movement.

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

Parámetros	Descripción
motor	The motor to set the timeout for. Choose from the motors configured in the Devices window.
tiempo	The number of seconds the motor can try to finish a movement. This can be a whole number or a decimal.

Ejemplo
