8 - Two-hand control devices

Last edit: 13/07/2023

The separation distance S from the nearest actuator to the hazard zone shall be calculated using the following euation:

S=(K×T)+D_DS

Where:

K=1600 [mm/s]

D_DS=550 [mm]

The standard prescribes that D_DS can be 0 if the risk of encroachment of the hands or part of the hands towards the hazard zone is eliminated and if the minimum allowable separation distance S is ≥ 100 [mm].

Safety in Collaborative Robotics

There is no “Collaborative Robot”. That is one of the first statements you hear from people working in Collaborative Robotics. The reason is because...
