A cobot may still need guarding

Determine safeguards from the application hazard, not from the commercial category of the robot.

FUURAA thesis

Collaborative operation is one risk-reduction option; unacceptable process or trapping risk can still require separation.

Engineering map

Turn the title into engineering objects that can be observed, measured and reviewed.

Each layer states the boundary to establish and the evidence needed for the next decision.

01

Process hazards

Review cutting, welding, heat, pressure, ejection, chemicals, electricity and stored energy.

02

Geometric hazards

Find crushing, trapping, shearing, sharp edges and restricted escape.

03

Safeguard selection

Combine elimination, design reduction, guards, sensing, procedures and information.

Verification questions

Write the questions first, then decide whether a demo, test, pilot or operating record can answer them.

Each question needs an object, conditions, denominator, threshold and accountable decision owner.

  1. 01

    Which hazards are unrelated to robot contact force?

  2. 02

    Where can a person be trapped despite low speed?

  3. 03

    Can the hazard be eliminated before adding sensing?

  4. 04

    Which phases still require physical separation?

Evidence to preserve

Enable the next reader to reconstruct conditions, results, failures and the decision.

A conclusion alone loses reviewability; raw records, configuration and exclusions matter too.

  1. 01

    Evidence package 1

    Application hazard and risk-reduction hierarchy

  2. 02

    Evidence package 2

    Safeguard selection and validation record

  3. 03

    Evidence package 3

    Residual-risk and access-control evidence

Scope boundary

State what this evidence still cannot be generalised to.
