The importance of measuring external loads for robots

Jan 5, 2014

Robots have been designed with specific torque and force sensors to help measure pressure and force of the external loads they are carrying. This increases the robots accuracy and efficiency, while also reducing the product damage. This also helps to increase the versatility of the system, helping it to adapt to many different shapes, sizes, and tolerances.


One of the newest safe­ty stan­dards recent­ly intro­duced by the IEC is the abil­i­ty for robots and humans to inter­act in clos­er prox­im­i­ty. This makes the abil­i­ty for robots to accu­rate­ly mea­sure their exter­nal loads more impor­tant than ever before. By being able to accu­rate­ly mea­sure the exter­nal loads being car­ried, robots are able to more pre­cise­ly sense the force need­ed for those loads.

Robots, includ­ing those robots that are made for work­ing hand in hand with human work­ers, have been out­fit with torque and force sen­sors that help robots to mea­sure the pres­sure and force nec­es­sary for mov­ing the exter­nal load they are car­ry­ing. This not only helps to make the robots move­ments more pre­dictable, but it also means that robots are more accu­rate­ly and effi­cient­ly work­ing for man­u­fac­tur­ers, which improves the pro­duc­tiv­i­ty for line over­all. The accu­rate mea­sure­ment of robot­ic exter­nal loads also improves the ver­sa­til­i­ty of the sys­tem, allow­ing it to adapt to many dif­fer­ent load shapes, sizes and tolerances.

Along with torque and force sen­sors to improve move­ment and force pre­dictabil­i­ty when mov­ing exter­nal loads for robots, these sys­tems also have touch sen­sors for exter­nal loads and move­ments, which allows them oper­ate more safe­ly in their space. Touch sen­sors allow a robot car­ry­ing a load exter­nal­ly to stop if some­thing comes into its motion path. This rais­es the safe­ty lev­el in a shop because a robot that is mov­ing at 100 per­cent oper­a­tion can move with enough force to kill a human work­er that moves into its work­space. Touch sen­sors, along with prop­er safe­ty train­ing for work­ers, can help min­i­mize this type of injury.
