Robot Safety — Robot Stop Distance Estimator
Robot Stop Distance Estimator calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066).
Stop distance grows with speed SQUARED — doubling TCP speed quadruples the braking part of the excursion. Manufacturers publish stop curves per axis, per load, per speed; this estimator brackets them for layout sketching before the real curves arrive with the robot.

About Robot Safety — Robot Stop Distance Estimator
Robot Safety — Robot Stop Distance Estimator computes the governing relationship d = v·t_react + v²/(2a) live as you type. Stop distance grows with speed SQUARED — doubling TCP speed quadruples the braking part of the excursion. Manufacturers publish stop curves per axis, per load, per speed; this estimator brackets them for layout sketching before the real curves arrive with the robot. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Robot Safety — Robot Stop Distance Estimator
- 1Enter your values — TCP speed, Controller reaction, Braking deceleration (sensible defaults are pre-filled).
- 2Read the live results: Stopping distance, Stopping time.
- 3Check the "with your numbers" line to see d = v·t_react + v²/(2a) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Robot Safety — Robot Stop Distance Estimator?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula d = v·t_react + v²/(2a) with authoritative sources cited on the page (ISO 13855 — Positioning of safeguards w.r.t. approach speeds; ISO 13857 — Safety distances (upper/lower limbs); ISO/TS 15066 — Collaborative robots: power & force limiting)
- ✓Stop distance grows with speed SQUARED — doubling TCP speed quadruples the braking part of the excursion.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the robot safety — robot stop distance estimator use?+
It evaluates d = v·t_react + v²/(2a), exactly as published. Sources: ISO 13855 — Positioning of safeguards w.r.t. approach speeds; ISO 13857 — Safety distances (upper/lower limbs); ISO/TS 15066 — Collaborative robots: power & force limiting. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Stop distance grows with speed SQUARED — doubling TCP speed quadruples the braking part of the excursion. Safety calculations here are layout-planning aids ONLY. The legally required values must come from the cited standards' full tables and a documented risk assessment by a qualified person.
When is this calculator the right tool for the job?+
Robot Stop Distance Estimator calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066). A free industrial robot kinematics & cell design tool. Manufacturers publish stop curves per axis, per load, per speed; this estimator brackets them for layout sketching before the real curves arrive with the robot. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
