Hi Vinay,
If you want to set the robot's velocity by directly publishing
messages to the cmd_vel topic (from the command line), try this:
rostopic pub /cmd_vel geometry_msgs/Twist '[0,0,0]' '[0,0,0]'

Replace the 0s for values you want to set, with the first 3 being
linear velocity and the latter 3 being angular velocity.
