How do you make a cobot safe?
Using a collaborative robot or a cobot can come with some safety concerns. The type of tooling, the gripper or the work-piece that is handled, can cause injury to those working alongside them. The amount of force and pressure that can be exerted in a collision could result in injury. Different parts of the body can receive different forces and pressures and it is the scope of the risk assessment to define these points.
Using the latest state of the art measuring equipment, Cobots and Machinery Safety Ltd can validate the cobot application ensuring that the forces and pressures are compliant with the requirements ISO TS 15066 and issue the necessary documents.

To evaluate not only the cobot system itself, but also the environment in which it is located, i.e. the workplace, a comprehensive risk assessment is required. This risk assessment will fall inline with the requirements of ISO TS 15066, EN ISO 12018-2 and EN ISO 12100 and will come at the design stage of the application.
The findings of the risk assessment will determine the corrective measures that can be applied, following the 3 stage method. The risk assessment should then be reviewed as the cobot application enters the commissioning stage, as new risks could have been created or not witnessed during the design stage. During the commissioning stage, it is important to validate the forces and pressures that can be exerted by the cobot movements. This is to ensure that in the unlikely event of a collision with the cobot, the operator is unharmed. As the cobot application is completed, the risk assessment should be closed out, ensuring that all hazards have been adequately reduced. This will then help to support the requirements of CE marking the cobot application.
