Teleop Twist Keyboard. In your terminal after starting teleop_twist_keyboard, do: rosmsg echo /cmd_vel Note that the twist keyboard might only work when its terminal window is active (click on it). I want to get teleop twist to work kind of like an RC car. Add possibility to publish TwistStamped messages. See also the roslaunch/XML/node documentation. This is a general ROS problem; it's not specific to teleop_twist_keyboard. }, class PublishThread(threading.Thread): if rlist: b : down (-z) If your mobile base requires constant updates on the cmd_vel topic, teleop_twist_keyboard can be configured to repeat the last command at a fixed interval, using the repeat_rate private parameter. How to make ROS differential drive robot move forward with teleop? settings = termios.tcgetattr(sys.stdin), teleop_twist_keyboard.py not working as expected. For me the simulation and teleop works fine. The /executive_usarsim/cmd_vel topic isn't published or subscribed to; why are you trying to echo it? self.x = 0.0 .
