Turtlebot Starts Path But Stops
My Turtlebot is able to localize and then start navigating to a desired point. But a second after it starts it gets lost and I start getting erros like this: Could not get robot pose, cancelling reconfiguration Extrapolation Error looking up robot pose: Lookup would require extrapolation at time 1476932209.270778684, but only time 1476932209.576979391 is in the buffer, when looking up transform from frame to frame I synced the clocks of my 2 machines. Any idea what the problem could be?
I synced the clocks again and AIML nav was working temporarily. But then the clocks stopped syncing again.
This seems to have been solved by syncing the clock on my turtlebot's computer with the clock on my workstation. Syncing them both to a external clock did not work properly.
