Introduction #

The VEX 123 Robot features a two-wheel drivetrain, allowing the robot to move forward and backward, and turn to the left and right. The Drivetrain blocks allow you to precisely control the robot’s movement and modify timeout settings and heading values.

Below is a list of available blocks:

Actions — Move and turn the robot.

drive — Drive the robot forward or in reverse continuously.
drive for — Drive the robot forward or in reverse for a specific distance.
drive until — Drive the robot until a specified condition is met.
turn — Turn the robot right or left continuously.
turn for — Turn the robot right or left for a specified amount of degrees.
turn to heading — Turn the robot to a specific heading.
stop driving — Stops all robot movement.

Settings — Configure drivetrain timeout and heading.

set drive timeout — Limits how long Drivetrain blocks wait to reach their goal.
set drive heading — Manually sets the robot’s heading value.

Values — Return drivetrain status and heading.

drive is done? — Returns a Boolean indicating whether or not the robot is done driving.
drive heading — Returns the drivetrain’s heading in degrees.

Actions #

drive #

The drive block moves the robot in the specified direction. This is a non-waiting block, meaning it runs continuously until another Drivetrain block interrupts it or the project stops.

Parameters	Description
direction	Drives the robot in one of the following directions: forward reverse

Parameters

Description

direction

Drives the robot in one of the following directions:

forward

conducir [atrás v] por (3) [pasos v]

drive until #

The drive until block is used to move the robot until a specified condition is met.

Conducir [adelante v] al [objeto v]

Parameters	Description
direction	Drives the robot in one of the following directions: forward reverse
condition	The condition that stops the robot: object — The Eye Sensor detects an object. crash — The robot crashes into another object. line — The Line Detector detects a line underneath the robot.

Parameters

Description

direction

Drives the robot in one of the following directions:

forward
reverse

condition

The condition that stops the robot:

object — The Eye Sensor detects an object.
crash — The robot crashes into another object.
line — The Line Detector detects a line underneath the robot.

Example

cuando empezó
[Reverse after a crash.]
Conducir [adelante v] al [choque v]
conducir [atrás v] por (1) [pasos v]

turn #

The turn block turns the drivetrain continuously left or right. This is a non-waiting block, meaning the drivetrain will keep turning until another Drivetrain block runs or the project stops.

turno [derecha v]

Parameters	Description
direction	The direction the robot will turn: left right

Parameters

Description

direction

The direction the robot will turn:

left
right

Example

cuando empezó
[Turn for 2 seconds.]
turno [derecha v]
esperar (2) segundos
deja de conducir

turn for #

The turn for block turns the drivetrain left or right for a specific number of degrees.

girar [derecha v] por (90) grado

Parameters	Description
direction	The direction the robot will turn: left right
angle	The angle, as an integer or decimal, at which the robot turns, ranging from -360 to 360 degrees.

Parameters

Description

direction

The direction the robot will turn:

left
right

angle

The angle, as an integer or decimal, at which the robot turns, ranging from -360 to 360 degrees.

Example

cuando empezó
[Turn left, then turn around to the right.]
girar [izquierda v] por (90) grado
girar [derecha v] por (180) grado

turn to heading #

The turn to heading block turns the drivetrain to face a specific heading.

girar hacia el rumbo (90) grados

Parameters	Description
heading	The absolute heading the drivetrain will turn to, from -360 to 360 degrees.

Example

cuando empezó
[Turn to face the cardinal directions.]
girar hacia el rumbo (90) grados
esperar (2) segundos
girar hacia el rumbo (180) grados
esperar (2) segundos
girar hacia el rumbo (270) grados
esperar (2) segundos
girar hacia el rumbo (0) grados
esperar (2) segundos

stop driving #

The stop driving block immediately stops all movement of the drivetrain.

deja de conducir

Parameters	Description
	This block has no parameters.

Example

cuando empezó
[Stop driving after 4 seconds.]
unidad [adelante v]
esperar [4] segundos
deja de conducir

Settings #

set drive timeout #

The set drive timeout block sets a time limit for how long a Drivetrain 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.

Note: The Drivetrain’s time limit is used to prevent Drivetrain blocks that do not reach their target position from stopping the execution of other blocks in the stack.

aria-description goes here#

Establezca el tiempo de espera de la unidad en (1) segundos

Parameters	Description
time	The maximum number of seconds a Drivetrain block will run before stopping and moving to the next block.

Example

When started, limits drive time to 1 second and then turns 90 degrees.#

cuando empezó
[Turn right after driving for 1 second.]
Establezca el tiempo de espera de la unidad en (1) segundos
conducir [adelante v] por (1000) [mm v]
girar [derecha v] por (90) grado

set drive heading #

The set drive heading block sets the robot’s current heading to a specified value.

aria-description goes here#

establecer el rumbo de la unidad a (0) grados

Parameters	Description
heading	The heading value to assign, in degrees.

Example

aria-description goes here#

cuando empezó
[Face the new 0 degree heading.]
establecer el rumbo de la unidad a (90) grados
girar hacia el rumbo (0) grados

Values #

drive is done?#

The drive is done? block returns a Boolean indicating whether the drivetrain is not moving.

True - The drivetrain is not moving.
False - The drivetrain is moving.

Note: This block detects movement only when it is caused by the drive for, drive until, turn for, or turn to heading blocks.

<¿La unidad está lista?>

Parameters	Description
	This block has no parameters.

Example

cuando empezó
[Glow blue after a crash.]
Conducir [adelante v] al [choque v]
para siempre
si <¿La unidad está lista?> entonces
resplandor [azul v]
demás
resplandor [verde v]

drive heading #

The drive heading block returns the drivetrain’s heading angle as a decimal number, in the range 0 to 359.99 degrees.

(rumbo de la unidad en grados)

Parameters	Description
	This block has no parameters.
