I'm using the kinetic-devel branch of the robotiq package and noticed that in the comments of rq_sensor.cpp, a "New interface with numerical commands" is mentioned in the receiverCallback function. Until now I've been unaware of these, as they don't seem to be mentioned anywhere except in the pull requests of the jade-devel branch of this package, which reference some old string-based commands like "SET ZRO". I am interested in using whatever the equivalent of "SET ZRO" is now to zero out my FT300 sensor before using its readings.

After some digging I've learned I need to use rosservice call robotiq_ft_sensor_acc [command_id] [command], but as for what [command_id] and [command] should be, other than an integer and string respectively, I have no clue. I have tried every combination of numbers and strings but the service always returns success: False and either res: !!binary | followed by some random short string of characters, or res:''. Also, occasionally the terminal running rq_sensor gives me a warning saying that I should use a numeric command instead of a string, something which the service doesn't seem to actually allow. It doesn't give this warning if I retry the same command a second time.

I'm very new to ROS so pardon me if this is a stupid question, but what commands are appropriate for this service? Or, where can I find documentation that tells me how robotiq_ft_sensor_acc is supposed to work?

Edit:

• Wiki page: http://wiki.ros.org/robotiq

• Github: https://github.com/ros-industrial/rob...

• robotiq_ft_sensor API: http://docs.ros.org/kinetic/api/robot...

Oh my gosh, I hadn't tried passing 8 "". That worked! Thank you!

I got a "not enough arguments" error by just passing 8 with no string.

Thank you. I tried using those constants to no avail, and I'm pretty sure leaving the string field blank gave me another

Yes! I've added everything I could find.

How do I use or find documentation for robotiq_ft_sensor_acc numerical commands? I'm using the kinetic-devel branch of t

Our lab is using Kinetic on Ubuntu 16.04 and we can't connect to our FT300 sensor with ROS. Using just the instructions in the FT300 manual (under the Development Package section), I was able to get sensor readings to show up in the terminal, so I do at least know my computer can make the connection. But rosrun robotiq_force_torque_sensor rq_sensor, which should do the same thing, just gives me lines and lines of "Waiting for sensor connection..." indefinitely. I've tried the following in various combinations:

• Using both the jade-devel and kinetic-devel branches of the Robotiq repository
• Specifying the exact \dev\ttyUSB* device that the sensor shows up as
• Modifying my files using TheDash's pull request that allows FT300 support

Unfortunately I lack the technical knowledge to know what the source of this problem is. As far as I can tell, the only fix is to downgrade to Ubuntu 14.04 and Indigo, since another lab has been able to get their FT300 working that way. Has anyone else run into this problem and managed to solve it somehow? Otherwise, can anyone give me a rough idea of how much headway has been made towards making this possible?

Thanks for reading.
