Payload Torque Check — Heavy Cobot (16 kg)
Static shoulder moment for a heavy cobot (16 kg) from payload, reach and arm mass — the gearbox-sizing number.
At 16 kg payload on a 900 mm reach, shoulder gravity torque alone approaches 200 N·m before any acceleration. The class survives because tasks live close-in: keep the work inside ~60% of reach and the same arm feels twice as stiff.
Formula
Note: Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.

About Payload Torque Check — Heavy Cobot (16 kg)
Payload Torque Check — Heavy Cobot (16 kg) computes the governing relationship M = m_p·(g+a)·r + m_arm·(g+a)·0.45r live as you type. At 16 kg payload on a 900 mm reach, shoulder gravity torque alone approaches 200 N·m before any acceleration. The class survives because tasks live close-in: keep the work inside ~60% of reach and the same arm feels twice as stiff. 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 Payload Torque Check — Heavy Cobot (16 kg)
- 1Enter your values — Payload (incl. gripper), Horizontal reach to load CG, Arm moving mass, Vertical acceleration (sensible defaults are pre-filled).
- 2Read the live results: Shoulder moment, Gravity-only moment, Payload share of moment.
- 3Check the "with your numbers" line to see M = m_p·(g+a)·r + m_arm·(g+a)·0.45r substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Payload Torque Check — Heavy Cobot (16 kg)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula M = m_p·(g+a)·r + m_arm·(g+a)·0.45r with authoritative sources cited on the page (Siciliano & Khatib (eds.), Springer Handbook of Robotics, 2nd ed.; ISO 9283 — Manipulating industrial robots: performance criteria)
- ✓At 16 kg payload on a 900 mm reach, shoulder gravity torque alone approaches 200 N·m before any acceleration.
- ✓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 payload torque check — heavy cobot (16 kg) use?+
It evaluates M = m_p·(g+a)·r + m_arm·(g+a)·0.45r, exactly as published. Sources: Siciliano & Khatib (eds.), Springer Handbook of Robotics, 2nd ed.; ISO 9283 — Manipulating industrial robots: performance criteria. 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?+
At 16 kg payload on a 900 mm reach, shoulder gravity torque alone approaches 200 N·m before any acceleration. Planning-level engineering estimate — final robot selection, guarding layout and risk assessment must follow the integrator's calculations and a documented ISO 12100/10218 risk assessment.
When is this calculator the right tool for the job?+
Static shoulder moment for a heavy cobot (16 kg) from payload, reach and arm mass. The class survives because tasks live close-in: keep the work inside ~60% of reach and the same arm feels twice as stiff. 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.
