You can use this wrapper for non-blocking service calls in Python: https://gist.github.com/jbohren/e3324...

I'm passing around dynamical properties (masses, inertias, etc) and there's no standard ROS message for a rigid body inertia with a coordinate frame and timestamp. Something like the following would be good (and simple):

Inertia.msg

# Mass [kg]
Float64 m
# First mass moment [kg-m]
geometry_msgs/Vector3 h
# Inertia Tensor [kg-m^2]
#     | ixx ixy ixz |
# I = | ixy iyy iyz |
#     | ixz iyz izz |
Float64 ixx
Float64 ixy
Float64 ixz
Float64 iyy
Float64 iyz
Float64 izz

InertiaStamped.msg

Header header
Inertia inertia

Anyone already using something like this? Maybe we could standardize it?

Update: Changed representation to use first mass moment instead of center of mass.

You can run ROS Indigo on Xenial pretty easily with Docker using the following: https://github.com/jbohren/rosdocked

Sorry, try:

export VERBOSE=1 && cd /home/laughlin/catkin_ws/build_isolated/collada_parser && /opt/ros/indigo/env.sh make -j4 -l4

Can you post the output of the following to a gist:

VERBOSE=1 cd /home/laughlin/catkin_ws/build_isolated/collada_parser && /opt/ros/indigo/env.sh make -j4 -l4

Positions are all in joint space, and the units depend on the kind of joint. The standard unit for revolute joints is radian, and the standard unit for prismatic joints is meters.

@gvdhoorn Unfortunately, ROS Index is statically-hosted by GitHub, so I need to run the updates locally, verify, and then push them. I'd like to make the updates more frequent though. I've set up a campaign to try to fund it here (no announcement yet): https://salt.bountysource.com/teams/r...

For h.264-encoded mp4 files, try using it with qtdemux with the following launchfile: https://gist.github.com/jbohren/4be3e...

What's the output of ls -l /home/hand/workspace/src/sr-ronex-indigo-devel/sr_ronex_drivers/cfg/GeneralIO.cfg ?

Edited....

You would need to create a NotSoSimpleActionState which accepts a timeout that can be used to monitor the actionlib status topic for the action. Have the state abort if this heartbeat timeout is violated.

The problem is that when the concurrence tries to preempt the SimpleActionState, it's trying to preempt the action, which will never preempt, because it has died.
