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.

from morse.builder import *

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

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

# place your component at the correct location
keyboard.translate(<x>, <y>, <z>)
keyboard.rotate(<rx>, <ry>, <rz>)

robot.append(keyboard)

# define one or several communication interface, like 'socket'
keyboard.add_interface(<interface>)

env = Environment('empty')
