6 years ago Hiya!
At the moment this is done off-ros_control or as part of a custom RobotHW implementation. I have some plans to add support for this soon, if all goes well I'll be able to dedicate some time to adding this feature. If you guys are interested I can make sure to add you to design and code review discussions.

Hi Guys,
Thanks for this framework! We are working on getting our robot to work with the use of ROS control and ethercat.

- https://github.com/tue-robotics/ethercat_interface/ (Ethercat interfacing)
We read encoder values and torques on the motor. We currently have a closed loop control running using the effort_controllers/JointPositionController https://github.com/ros-controls/ros_controllers/blob/kinetic-devel/effort_controllers/src/joint_position_controller.cpp .
However, we do have relative encoders. So we need to null the encoders using end-stop homing, absolute encoders or other sensors. How do you usually solve this?
Thanks,
