Hi all. I’m new in Ros, and needing some help to follow the tutorials.
When I type ( $ rostopic pub -1 /turtle1/cmd_vel geometry_msg/Twist -- `[2.0, 0.0, 0.0]´ ´[0.0, 0.0, 1.8] )
The previous command sends a message to turtlesim to move an linear velocity of 2.0 and an angular velocity of 1.8.
I get this ( ERROR: invalid message type: geometry_msg/Twist. )
Anibody cam tel me where did I go wrong?
I´m using ros hidro on ubuntu 12 lts, inside a virtualbox vm.
Thanks for all.
