Reading a robot datasheet without being misled

Payload

Check whether the figure includes end-of-arm tooling and inertia; real payload is usually lower.

Cycle time

Test conditions (path length, payload, acceleration) change the number substantially.

Repeatability

Ask for the measurement standard: ISO 9283 or an internal method, and at what payload.

Method note: no vendor endorsement. Where public sources are cited, verify against the publisher's original text.
