ISO/TS 15066 Trajectory Validation Checklist (FDA-Ready)
The ISO/TS 15066 Trajectory Validation Checklist (FDA-Ready) is a structured, regulatory-aligned verification protocol used to ensure that collaborative robot (cobot) motion trajectories comply with human safety requirements defined in ISO/TS 15066—particularly power and force limits—and meet FDA expectations for validation rigor in regulated life sciences environments. It bridges robotic safety standards with quality system requirements (e.g., FDA 21 CFR Part 820, ICH Q9/Q10) by enforcing traceable, documented, and repeatable trajectory safety assessments. The checklist mandates evidence of worst-case scenario analysis, dynamic parameter measurement (e.g., actual contact forces), and configuration control across software/firmware versions.
📖 Overview
📑 Key Components
🎯 Applications
- ✓ Validation of cobot-assisted aseptic filling systems
- ✓ Safety qualification of robotic lab automation in GxP-regulated R&D
- ✓ Post-deployment trajectory revalidation after firmware updates in FDA-cleared medical devices
📐 Key Formulas
Contact Force Limit (ISO/TS 15066, Table B.1)
F_{lim} = \min\left(150\ \text{N},\ 250 - 10 \cdot t_{contact}\right) \quad \text{for } t_{contact} \in [0.1, 0.5]\ \text{s}
Maximum allowable quasi-static contact force for upper limbs, dependent on measured contact duration
Power Limit (ISO/TS 15066, Clause 6.3.2)
P_{lim} = \frac{F_{meas} \cdot v_{rel}}{\eta} \leq 10\ \text{W}
Validated instantaneous power at point of contact, where F_meas is measured force, v_rel is relative velocity normal to surface, and η is energy absorption efficiency (typically 0.8–1.0)
Measurement Uncertainty Budget (FDA-Ready Requirement)
U_{total} = \sqrt{u_{sensor}^2 + u_{calibration}^2 + u_{temp\_drift}^2 + u_{sampling\_rate}^2}
Combined standard uncertainty for force/torque measurements, required to be ≤10% of applicable limit per FDA guidance on measurement system analysis
