Revision history [back]

Hi, So... if I understood correctly, I could be able to move the robot everywhere without using the angular velocity parameter, right? I have tried and I can't manage to get it right: I can move the robot left and right (as seen in the screenshot) with the following commands:

rostopic pub /cmd_vel geometry_msgs/Twist -r 1 '[10, 0, 0]' '[0, 0, 0]'

and back to the inverted direction (right):

rostopic pub /cmd_vel geometry_msgs/Twist -r 1 '[-10, 0, 0]' '[0, 0, 0]'

I tried playing with the rest of coordinates (using y or z, but they didn't produce any visible result). I also tried to use the angular velocity parameter by themselves, but I couldn't manage to make the robot move.

Any suggestions would be appreciated, thanks :)!
