Position control versus torque control. What method is commonly used in industral manipulators

$\begingroup$ Welcome to Robotics Pari, but I'm afraid that questions like this really aren't a good fit for a stack exchange site. We prefer practical, answerable questions based on actual problems that you face. Take a look at How to Ask and tour for more information on how stack exchange works. Also, the Robotics question checklist has good advice on how to write a good question. $\endgroup$ – Mark Booth♦ Mar 27 '17 at 15:39
In my experience, most pick and place robots use a version of position control, which they augment with feedforward dynamic models for improved speed and reduced errors. Those robots which maintain contact with the environment (such as grinding, deburring, cutting, etc) usually implement a hybrid force/position control.
