Calling zero_ftsensor() is failing

Hello!

I am trying to zero out the F/T sensor using the script command zero_ftsensor(). I have called it in the program tree using a script node and printed the force() values as well as full get_tcp_force() values before and after the call and the zero_ftsensor() method appears to do nothing.

I am running this on Polyscope 5.19 with a UR 10e. I am able to get this exact workflow to work on a different system with the same software versions, it just occurs on sporadic systems. This makes me think it isn’t necessarily a software bug and that something else is off with the system. I checked the ftsensor.conf file as mentioned by this thread and it seems to be in good condition.

Our force sensor does seem to be putting out some weird and random values, perhaps it is going bad? I don’t know how I would check that, but it occurred to me as a possibility.

I’d appreciate any ideas on what is happening!

Thanks

We discovered that we most likely had a faulty force sensor. We replaced the tool flange with a good force sensor and zero_ftsensor() worked as expected. Our force values became more consistent as well.
