data_publisher publishes at varying rates. #45

Closed GoogleCodeExporter closed 8 years ago

Data publishing needs to keep up with updates from rtai_controller.

Currently, data_publisher lags (on average) behind rtai_controller by 5 to 10 
seconds per minute.

The lag is not affected by the location of the ROS master node, so network 
connection speeds is probably not the bottleneck.

If publishing is disabled, the loop exceeds rtai_controller updates by 10 to 20 
seconds per minute.

As long as nettop isn't occupied with other processes, data_publisher 
consistently publishes at 1 kHz.
