A collaborative-robot safety architecture using redundant joint position sensing and configurable speed/force limits so a manipulator can operate beside humans without a full cage.
Claims
Claims recite redundant position sensors at joints, monitoring for disagreement, and triggering safety functions that constrain joint speed/torque when limits are exceeded.
Technical analysis
This is the legal/engineering backbone of the UR cobot category: safety is not a software afterthought but dual-channel sensing with hard stop behavior. Without redundant sensing stories, CE/UL collaborative claims collapse.
Commercial impact
Underpins Universal Robots’ dominance in SME cobots. Integrators cite these mechanisms when justifying UR10e deployments next to operators instead of behind fences.
