Hi, can you help me to use the topic channel_feedback() in rqt-rviz? Can I use this topic to read values of current/effort and so adjourn position in the topic channel_target? Thank you.

yes, it seemed so.

have you read 5.2 standalone usage ?

If you want to check out that everything is working or just want to move the hand into any position you can use the package as standalone with sliders.......the hand is ready and fingers can be moved by using the Joint State publisher gui that has come up.

this joint-state-publisher is using then the topic channel_target to setup a new position of a finger

Hey Alba,

As Inflo pointed out you can use the default GUI provided with the Joint state publisher in standalone usage. This will give you a slider window to use. The plugin SVH Reset also gives you the option to trigger a connect and reset calls. Maybe i could add sliders to this window as well.

Currently the channel feedback will only give you the current position of the fingers, not the current values or effort. You can however read this via API calls. This might be added in a next release.

Best Regards Georg
