i have meet an interesting thing: system:win10 vmware15.5pro ubuntu18.04 ros melodic(which is not important) when runing :

rostopic pub turtle1/cmd_vel geometry_msgs/Twist "linear:
  x: 200.0
  y: 0.0
  z: 0.0
angular:
  x: 0.0
  y: 0.0
  z: 200.0" -r 10

i surpose to see a empty circle,but i see a full circle.but the turtle should not have the chance to walk through the circle.actually it take the shorter way rather then quickly go round.

(and as you can see i have a poor english......)

Hi,

The first thing to understand is why you are sending that command. You are just commanding the base to go 200m/s and 200 rad/s. That values are too high to control the platform properly.
