Error in deploy.lua import

[amine-abm]

Hello,

In my deploy.lua, I imported the following pkgs:

d:import("rtt_rosnode")
d:import("rtt_ros")
d:import("rtt_roscomm")
d:import("eigen_typekit")
d:import("kdl_typekit")
ros = gs:provides("ros")
ros:import("lwr_fri")

when I try to stream JointVelocity (of type <Eigen::VectorXd >) using:

d:stream("FRI.JointVelocity",ros:topic("/joint_velocity"))

I get the following error:

[ Warning] The protocol with id 3 did not register a fall-back handler for unknown types!
[ Warning]   triggered by: unknown_t which does not have a transport.
[ ERROR  ] Could not create transport stream for port JointVelocity with transport id 3
[ ERROR  ] No such transport registered. Check your policy.transport settings or add the transport for type eigen_vector

Are there any missing import ? or it is related to another issue?

Thanks for the help

The streaming to the ros topic is supported only for ros types (generated
from ros idl .msg).
The FRI.JointVelocity is Eigen::VectorXd so it can't be used directly with
ros communication mechanisms.

Which packages I should use to do the conversion of these data?
Note that "lwr_impedance_controller" package in https://github.com/RCPRG-ros-pkg/lwr_robot/tree/master/lwr_impedance_controller is not updated with catkin

you can use joint state publisher from
https://github.com/RCPRG-ros-pkg/orocos_controllers
