`robotics` – Robotics module¶

Robotics module for the Pybricks API.

class DriveBase(left_motor, right_motor, wheel_diameter, axle_track)¶

Class representing a robotic vehicle with two powered wheels and optional wheel caster(s).

Parameters:	left_motor (Motor) – The motor that drives the left wheel. right_motor (Motor) – The motor that drives the right wheel. wheel_diameter (dimension: mm) – Diameter of the wheels. axle_track (dimension: mm) – Distance between the midpoints of the two wheels.

Example:

# Initialize two motors and a drive base
left = Motor(Port.B)
right = Motor(Port.C)
robot = DriveBase(left, right, 56, 114)

drive(speed, steering)¶

Start driving at the specified speed and turnrate, both measured at the center point between the wheels of the robot.

Parameters:	speed (speed: mm/s) – Forward speed of the robot. steering (rotational speed: deg/s) – Turn rate of the robot.

Example:

# Initialize two motors and a drive base
left = Motor(Port.B)
right = Motor(Port.C)
robot = DriveBase(left, right, 56, 114)

# Initialize a sensor
sensor = UltrasonicSensor(Port.S4)

# Drive forward until an object is detected
robot.drive(100, 0)
while sensor.distance() > 500:
    wait(10)
robot.stop()

drive_time(speed, steering, time)¶

Drive at the specified speed and turnrate for a given amount of time, and then stop.

Parameters:	speed (speed: mm/s) – Forward speed of the robot. steering (rotational speed: deg/s) – Turn rate of the robot. time (time: ms) – Duration of the maneuver.

Example:

# Drive forward at 100 mm/s for two seconds
robot.drive(100, 0, 2000)

# Turn at 45 deg/s for three seconds
robot.drive(0, 45, 3000)

stop(stop_type=Stop.COAST)¶

Stop the robot.

Parameters:	stop_type (Stop) – Whether to coast, brake, or hold (Default: `Stop.COAST`).
