This looks like a Python 2/3 issue, especially since you've added the kinetic tag (which is still using Python 2). Try u

I've also run into this problem. I did some experimenting but didn't have much success. More details here.

Yup, I'm familiar with PCL. Since MoveIt takes an octomap::OcTree as input, what I'd really like is the PCL setOccupiedV

I don't think so. The documentation implies that it does raytrace.

Thanks--I've mostly just used ROS in C++, and so I basically didn't expect an out-of-date bagfile to open at all. The o

I have two message types being published on two different topics (pretty much synchronously), and I'm merging them into a single message--basically, adding one as a subtype of the other. I'd like to migrate old bags to this new arrangement, but I'm pretty sure the tools in rosbag are not capable of this. Is there a lower-level approach to migrating bags that might work? How can I access both the old and new message definitions in a Python script?

I found a workaround. In the test script, simply launch a rosout node, but with a different name: <node name="rosout

Well, it is starting, because when I try to start one myself in the .test file, I get the duplicate-node-name error. So

How to make rostest launch rosout? I have a node that analyzes rosout_agg messages to benchmark the robot's performance.

This is only a half-answer, which I've figured out while debugging a similar problem. Yes, test nodes do publish to ros
