Use Common Start and End Conditions in Robot Acceptance Tests

Two robot solutions can perform the same action yet produce incomparable times if measurement starts or ends at different events. Agree the task events and measurement method first.

Define the start event

Specify whether timing begins at task receipt, part availability, operator confirmation or robot motion, and use the same definition for each solution.

Define the end event

State whether the end requires stable placement, release, handover confirmation or robot return to standby.

Review the timing source

Retain source and precision for device logs, external timing or manual records; check time bases when comparing systems.

Explain waits and exceptions

State how feed waits, retries, stoppages and intervention are counted rather than basing procurement on ideal cycles alone.

Applying the checklist: a hypothetical example

If one party times from robot motion and another from part availability, align the events and still record feed waiting and equipment motion separately before comparing numbers.
