No response on kobuki_testsuite test_rotation.py and test_translation.py

Dear kobuki friends,

We went through testsuite and everything works great except below two tests:

rosrun kobuki_testsuite test_rotation.py rosrun kobuki_testsuite test_translation.py

Above two tests have no physical response, though it prints out messages on screen, for example of test_rotation.py:

We also tested roslaunch kobuki_keyop safe_keyop.launch --screen , the control works great. So were wondering why simpler test_rotation.py and test_translation.py don't work. (We are using Ubuntu 18.04 + Melodic)

Hope to hear your expertise.
