Streaming Data

by RoboGuy » Thu Nov 14, 2013 11:23 am

Hi

I am streaming data from Arena to a ROS Node that outputs the data coordinates. However I am not having too much success with that. Is there some program that I can stream the data to just so that I can get possibly a text file with the coordinates. Also if I have recorded data, would I be able to stream that? The next question is do I actually need to stream the data to get the coordinates or is there some way that I can extract the coordinates from recorded data from Arena itself?

Arena supports streaming marker and joint angle data via the NatNet SDK. Are you having trouble getting the NatNet SDK samples to work?

If you do not need live export, you can also export your data via C3D or BVH files.

Alternatively, our newer software, Motive has several new methods for getting data.

By file:
- BVH
- C3D
- FBX
- CSV (plain text)

Live / Streaming:
- NatNet
- VRPN
- trackD
- Direct UDP

Hope this helps,

Morgan
