Not checked
- no joint appears in both runs with the same command, so nothing was compared
Both runs are simulations: the observed run stands in for a real joint until a device posts one with source device:<id>.
The observed run carries 0.3 kg on tool; the prediction carries 3 kg on tool.
The observed run was at 60 C ambient and the prediction at 25 C.
The runs last 120 s and 20 s; each joint is compared over the time both cover.
The observed scenario is "min-jerk reach and hold, payload at the tool, 60 C enclosure" and the prediction's is "min-jerk reach and hold, payload past the shoulder's peak torque".
- Observed
- Printed arm, stand test watch

- Rules
- command within 0.01 rad rms; position watch 0.02 rad rms, fault 0.1 rad max; current watch 25%; winding watch 5 °C, fault 15 °C
