Most methods which run motors will accept a speed argument. While this can be provided as an integer which will be interpreted as a percentage of max speed, you can also specify an instance of any of the following classes, each of which represents a different unit system:. A base class for other unit types. Bases: ev3dev2. The motor class provides a uniform interface for using motors with positional and directional feedback such as the EV3 and NXT motors. This feedback allows for precise control of the motors. This is the most common type of motor, so we just call it motor. Run to a position relative to the current position value. Reset all of the motor parameter attributes to their default value. This will also have the effect of stopping the motor. With normal polarity, a positive duty cycle will cause the motor to rotate clockwise. With inversed polarity, a positive duty cycle will cause the motor to rotate counter-clockwise. Power will be removed from the motor and a passive electrical load will be placed on the motor. This is usually done by shorting the motor terminals together. This load will absorb the energy from the rotation of the motors and cause the motor to stop more quickly than coasting. Does not remove power from the motor. Instead it actively try to hold the motor at the current position. If an external force tries to turn the motor, the motor will push back to maintain its position. Sends a command to the motor controller. See commands for a list of possible values. Returns a list of commands that are supported by the motor controller. Possible values are run-foreverrun-to-abs-posrun-to-rel-posrun-timedrun-directstop and reset. Not all commands may be supported. Returns the number of tacho counts in one rotation of the motor. Tacho counts are used by the position and speed attributes, so you can use this value to convert rotations or degrees to tacho counts. Returns the number of tacho counts in one meter of travel of the motor.

Released: Mar 23, View statistics for this project via Libraries. A Python3 library implementing an interface for ev3dev devices, letting you control motors, sensors, hardware buttons, LCD displays and more from Python code. This library runs on ev3dev. Before continuing, make sure that you have set up your EV3 or other ev3dev device as explained in the ev3dev Getting Started guide. Make sure you have an ev3dev-stretch version greater than 2. We recommend the ev3dev Visual Studio Code extension. Otherwise, you can can work with files via an SSH connection with an editor such as nanouse the Python interactive REPL type python3or roll your own solution. The first line should be included in every Python program you write for ev3dev. It allows you to run this program from Brickman, the graphical menu that you see on the device screen. The other lines are import statements which give you access to the library functionality. You will need to add additional classes to the import list if you want to use other types of devices or additional utilities. You should use the. This is usually in the status bar at the bottom. For help, see our FAQ page. To be able to run your Python file, your program must be executable. If you are using the ev3dev Visual Studio Code extensionyou can skip this step, as it will be automatically performed when you download your code to the brick. You can now run my-file. Plug a touch sensor into any sensor port before trying this out. Heads-up: If you are using a BrickPi instead of an EV3, you will need to manually configure the sensor. You can also run a motor for a number of degrees, an amount of time, or simply start it and let it run until you tell it to stop. Additionally, other units are also available. See the following pages for more information:. There are also MoveSteering and MoveJoystick classes which provide different styles of control. There are several demo programs that you can run to get acquainted with this language binding. The programs are available at this GitHub site. You can also copy and run the programs in the utils directory to understand some of the code constructs to use the EV3 motors, sensors, LCD console, buttons, sound, and LEDs.

Note: If you are using a BrickPi rather than an EV3, you will need to manually configure the ports before interacting with your sensors. See the example here. These classes derive from ev3dev2. Sensor and provide helper functions specific to the corresponding sensor type. Each provides sensible property accessors for the main functionality of the sensor. Bases: ev3dev2. Wait for the touch sensor to be pressed down and then released. Officially in the range but the values returned will never be that high. We do not yet know why the values returned are low, but pointing the color sensor at a well lit sheet of white paper will return values in the range. The RGB raw values are on a scale of but you never see a value anywhere close to This function is designed to be called when the sensor is placed over a white object in order to figure out what are the maximum RGB values the robot can expect to see. We will use these maximum values to scale future raw values to a range in rgb. This default was selected by measuring the RGB values of a white sheet of paper in a well lit room. Note that there are several variables that influence the maximum RGB values detected by the color sensor - the distance of the color sensor to the white object - the amount of light in the room - shadows that the robot casts on the sensor. Prefer using the equivalent UltrasonicSensor. If you use this property too frequently e. A delay of msec between each usage seems sufficient to keep the sensor from locking up. Equivalent to UltrasonicSensor. As the gryo rotates clockwise the angle increases, it will increase by for each full rotation. As the gyro rotates counter-clockwise the gyro angle will decrease. The angles on a circle have the opposite behavior though, they start at 0 and increase as you move counter-clockwise around the circle. Convert the gyro angle to the angle on a circle. We consider the initial position of the gyro to be at 90 degrees on the cirlce. Sensorev3dev2. Handler for top-left button events on channel 1. See InfraredSensor.
