Keyboard Actuator

A ‘fake’ actuator that allows to move a robot from the keyboard.

This actuator does not require a connection with external data. It simply responds to the keyboard arrows to generate movement instructions for the robot attached.

When parented to a robot, the user can press the arrow keys to modify the linear and angular velocities (V, W) of the robot.

Configuration parameters for Keyboard Actuator

You can set these properties in your scripts with <component>.properties(<property1>=..., <property2>=...).

  • ControlType (string, default: "Position")
    Kind of control to move the parent robot, in [‘Position’, ‘Velocity’, ‘Differential’]
  • Speed (float, default: 1.0)
    Movement speed of the parent robot, in m/s

Data fields

No data field documented (see above for possible notes).

Services for Keyboard Actuator

  • get_configurations() (blocking)

    Returns the configurations of a component (parsed from the properties).

    • Return value

      a dictionary of the current component’s configurations

  • get_properties() (blocking)

    Returns the properties of a component.

    • Return value

      a dictionary of the current component’s properties

  • set_property(prop_name, prop_val) (blocking)

    Modify one property on a component

    • Parameters

      • prop_name: the name of the property to modify (as shown the documentation)
      • prop_val: the new value of the property. Note that there is no checking about the type of the value so be careful
    • Return value



The following examples show how to use this component in a Builder script:

from morse.builder import *

# adds a default robot (the MORSE mascott!)
robot = Morsy()

# creates a new instance of the actuator
keyboard = Keyboard()

env = Environment('empty')

# Run this simulation: you can move the robot with the arrow keys.
