Hi,

In the first unit you use this launch:

roslaunch catvehicle_tests cmdvel_unsafetest.launch

This launch essentially publishes into the topic:

rostopic pub /catvehicle/cmd_vel_safe geometry_msgs/Twist "linear:
  x: 1.0
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 0.0" -r1

If you do this manually you will see that it doens’t matter if there is an obstacle , like the street cone there is in the middle of the road. It will collide with it.

So you can use this topic to move the car , without talking into account the obstacles.

thank you so much. i did the simulation. is there any way to increase the speed.whatever the values i gave for speed, the vehicle is moving slow.
