Known limits
What this record does not prove.
- The 5.46 mN·m value is a short-time limit and must not be presented as continuous torque.
- An integrated motor controller does not establish a robot-axis safety or motion-control system.
- No RCI physical, thermal, gearing, accuracy or life test exists.
