Which force given by gripper.get_force under SDK mode

Hi All,

I am sorry to bother but recently I am trying to figure out which force the gripper.get_force gives us under the SDK mode. Since gripper.get_force will give us just a number so I wonder what this number means. I read some materials given by Rethink Robotics and they say that the force is computed from the torque at "some" joint so I wonder about whether you have some documents telling us how you compute the overall force given by torques from joints. I would really appreciate it if you could spend some time replying and sharing your ideas. Thanks!

Thanks,

Yayun

Hi Yayun,

Thank you for using Sawyer SDK robot!

For your question 'gripper.get_force', it is the force sensed by the gripper in estimated Newtons, the unit is Newton-Meters (N-m).

We use electric current to calculate the grippering force for the electrical gripper.

Hope this helps.
