I'm looking for a stepper motor w/encoder that works with ROS. Does anyone know of a good one that has documentation about how to use it with ROS?

Thanks in advance.

neural network. but then not do any forward passes until a flag is triggered.

Thanks for the comments. The node does use a lot of resources which is why I want to shut it down. I ended up using the

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.

I synced the clocks again and AIML nav was working temporarily. But then the clocks stopped syncing again.

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 actually figure it out. The problems were that the map dimension params were set to be too small and that I was moving the robot too fast. If I let it sit for few seconds it mapped fine. But my new problem is that when I start AIML using RVIZ for autonomous navigation it isn't working to great.

I am using gmapping slam_gmapping and rosrun map_server map_saver. The saved map has only part of my apartment. The saved part is the largest room in my house. The rest of the house (Hallway, kitchen) are missing.

I have been trying to build a map of my apartment using my Teleoperation with a turtlebot 2. The map seems to look fine on rviz initially but when I save and try to use it with autonomous nav the map is incomplete. It seems to be missing the narrower parts of my apartment like my hallway and kitchen.
