frame_id sensor_base does not exist.

@shiqizhang6 found this error today. We can take a look at it tomorrow.

piyushk@robot-devil:~/newrobot/src$ grep -r "sensor_base" *

segbot/segbot_sensors/src/sonar/range_to_cloud.cpp:    cloud->header.frame_id = "sensor_base"; // TODO: make this a parameter

Looking at the tf tree, sensor_base is not a frame_id on the tree. What was this supposed to be?

[jack-oquin]

That was supposed to be the frame of the base plate on which the arduino, sonars and other sensors are mounted. It may not be necessary, as long as all the sonar and other sensor frames are suitably defined.
