keystroke_listen Node
Run with ros2 run keystroke kesytroke_listen
Parameters: - exit_on_esc (boolean, default True): Whether the escape key should cause this node to exit
Published Topics: - /glyphkey_pressed (String) - Pressing a letter/number/symbol key - /key_pressed (UInt32) - Pressing spacebar, ctrl, F1, etc.
arrows_to_twist Node
Run with ros2 run keystroke_arrows_to_twist
Parameters: - publish_period (float): How often to publish the speed - linear_scale (float): How much to increase/decrease speed based on up/down arrows - angular_scale (float): How much to increase/decrease angular speed based on left/right arrows
Subscribed topics: - /key_pressed (Uint32) - Keypresses to translate to speed commands
Published topics: - /cmd_vel (Twist) - Velocity (linear and angular) commands
