Sphero robot don't move when I publish in cmd_vel topic [closed]

edit

Hello!

I try to make a project using sphero robot simulation(gazebo) from this source: Sphero-ROS.

I run the command: roslaunch sphero_gazebo main.launch to start gazebo.

After that I tried to move the robot by keyboard, running the next command in other terminal: roslaunch sphero_gazebo keyboard_teleop.launch. But when I pres the control keys, the robot do not respond.

I tried also to move the robot by terminal running:

rostopic pub /cmd_vel geometry_msgs/Twist "linear:
  x: 1.0
  y: 0.0
  z: 10.0
angular:
  x: 0.0
  y: 0.0
  z: 0.0"

But did't work. I do not receive any error in console. How can I solve this?

I am using ROS Kinetic.

edit:

I tried to echo the /cmd_vel topic in one terminal and in the second one I published using the command above and everything looks like working but the robot don't move.
