DRCSIM ROS Topics Synchronization.

Is there any mechanism to efficiently synchronize DRCSIM ROS topics? In a real robot the synchronization would happen with the control system tick. However, as the clock, force sensors, joint states, etc... update at the "same time" i cannot be sure that all the other variables have already being updated when triggering my control with clock callback.

Best regards,

I posted a question to answers.ros trying to get around this issue. Waiting and testing to see that all data is received and processed before doing controls calculations is fraught with peril, and will likely cause significant issues due to latency.

it's been further updated to, as the originally proposed state message gets fragmented.
