I am working along with the person who posted the original question.

I am able to connect to the robot but we can't get the pose as well as we can't set any velocity to make it move. Actually, we could able to move the robot properly 2 days back with same commands in the same PC. May be we are missing something today?

Also, I downloaded the latest version of ROSARIA today and tried. But, no success.

Below is the output from the terminal:

raj@ubuntu:~$ rosrun rosaria RosAria _port:=/dev/ttyUSB0 [rospack] Error: stack/package rosaria not found Could not connect to simulator, connecting to robot through serial port /dev/ttyUSB0.
