($rosrun executive_usarsim usarsim_manager.py), this command opens a connect USARSIM UI through which i can connect ROS to the USARSim and can spawn a P3AT robot in USARSim. The Teleop could work, but the robot could not pick up the instructions from it. I want to get teleop twist to work kind of like an RC car. ROS2 allows asynchronous services and so the overhead of an action interface is no longer warranted. I have connected ros to usarsim using executive_usarsim package and spawned the P3AT robot in usarsim, but when i run teleop_twist_keyboard and presses keys to move the robot, nothing happens. please help me out. platform == 'win32': import msvcrt else: import termios import tty TwistMsg = Twist msg = """ Reading from the keyboard and Publishing to Twist! b : down (-z) Released Continuous Integration Documented Generic keyboard teleop for twist robots. self.publisher = rospy.Publisher('cmd_vel', Twist, queue_size = 1) The documentation at ROS.org is a great resource for that.
