Robot Safety — Laser Scanner Protective Field
Laser Scanner Protective Field calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066).
Walking approach uses K = 1,600 mm/s, but the C-term is the surprise: a scanner plane at ankle height needs ~850 mm of extra field because a fast walker's body leans over the detection plane before their legs enter it. Field shape matters as much as depth — cover the sneak paths behind the cell.
Formula
Note: 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.

About Robot Safety — Laser Scanner Protective Field
Robot Safety — Laser Scanner Protective Field computes the governing relationship S = 1600·T + C, C = 1200 − 0.4·H (≥ 850 mm) [ISO 13855 walking approach] live as you type. Walking approach uses K = 1,600 mm/s, but the C-term is the surprise: a scanner plane at ankle height needs ~850 mm of extra field because a fast walker's body leans over the detection plane before their legs enter it. Field shape matters as much as depth — cover the sneak paths behind the cell. 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 — Laser Scanner Protective Field
- 1Enter your values — Total stopping time T, Scan plane height (sensible defaults are pre-filled).
- 2Read the live results: Protective field depth, Approach allowance C.
- 3Check the "with your numbers" line to see S = 1600·T + C, C = 1200 − 0.4·H (≥ 850 mm) [ISO 13855 walking approach] substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Robot Safety — Laser Scanner Protective Field?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula S = 1600·T + C, C = 1200 − 0.4·H (≥ 850 mm) [ISO 13855 walking approach] 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)
- ✓Walking approach uses K = 1,600 mm/s, but the C-term is the surprise: a scanner plane at ankle height needs ~850 mm of extra field because a fast walker's body leans over the detection plane before their legs enter it.
- ✓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 — laser scanner protective field use?+
It evaluates S = 1600·T + C, C = 1200 − 0.4·H (≥ 850 mm) [ISO 13855 walking approach], 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?+
Walking approach uses K = 1,600 mm/s, but the C-term is the surprise: a scanner plane at ankle height needs ~850 mm of extra field because a fast walker's body leans over the detection plane before their legs enter it. 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?+
Laser Scanner Protective Field calculation per the machinery-safety standards (ISO 13855/13857, ISO 10218, ISO/TS 15066). A free industrial robot kinematics & cell design tool. Field shape matters as much as depth — cover the sneak paths behind the cell. 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.
