Does the osrobot-uav multirotor energy model match real aircraft?

What it found

Checks the osrobot-uav multirotor power model (imported unchanged) against two aircraft with a published mass, pack energy and endurance: DJI Mavic 3E (1.050 kg, 77 Wh, 45 min) and Parrot Anafi UKR (1.450 kg, 78.5 Wh, 38 min at 21.6 km/h), taken from Wikipedia's specification tables. Rotor diameter is not in the sources, so it is swept from 0.15 to 0.30 m: the model's endurance over the published one runs from 0.68 to 2.21 (Mavic) and 0.47 to 1.47 (Anafi). The model matches the published endurance at 0.181 m (Mavic) and 0.248 m (Anafi) at 90 % usable energy. At 0.22 m the errors have opposite signs (1.31× and 0.85×). Two aircraft of one class only; the fixed-wing and VTOL models are not tested; figures are from a secondary source and manufacturer maxima. Update: DJI's listing gives the Mavic 3 propellers as 9.4 in (0.239 m); at that diameter the model gives 1.30 to 1.63× the published endurance (80 to 100 % usable), so the earlier matching diameter of 0.18 m was a fit to a wrong model, not a rotor size. The Anafi diameter is still unsourced.

• Is one slow weeding pass better than several fast ones, and does treating on the move change that?A laser-weeding robot that drives three fast passes (4 km/h) kills 0.780 of the weeds in 75 min, against 0.607 in 83 min for one slow pass (1 km/h), and treating on the move instead of stopping cuts time by 6% at 0.3 weeds/m² and 39% at 3 weeds/m²; the ranking survives 30% of weeds being invisible to the detector
• Do several fast laser-weeding passes still beat one slow pass when the detector's hit rate comes from published field trials?With a detector fitted to two published field detection rates (88.9% at 0.2 m/s, 86.2% at 0.425 m/s), two laser-weeding passes at 4 km/h kill 0.952 in 40 min against 0.875 in 68 min for one pass at 1 km/h; the ranking holds, and the share of weeds the detector never sees (3 passes cap at 0.897 with 10% hidden) now sets the ceiling
• When does a purpose-built gantry beat a general two-link arm at tray pick-and-place?When does a purpose-built gantry beat a general two-link arm at tray pick-and-place? At 2 mm tolerance the arm wins only between 0.36 and 0.99 m of work area, and the band depends on assumed costs (stylised).
• Does co-designing an arm's link lengths and controller beat tuning the controller on a fixed body?Does co-designing an arm's link split and controller beat tuning the controller on a fixed body? Co-design gained 1.9% in held-out move time (0.283 against 0.289 s), within three-seed noise; tuning the controller mattered about 37%. Stylised, preliminary, mostly negative.
• Can a small twin of a liquid-handling bench catch protocol errors before they run, and how much pipetting error does a serial dilution tolerate?Can a small twin of a liquid-handling bench catch protocol errors before they run, and how much pipetting error does a serial dilution tolerate? It flags 366 of 522 injected faults against 100 for a syntax-only baseline, and an assumed error curve gives a final-well CV of 0.187 at 10 µL and 0.035 at 100 µL transfers (stylised, circular fault set).
• Does the real Opentrons simulator catch the protocol faults a small stdlib liquid-handling twin catches?Does the real Opentrons simulator catch the faults the stdlib liquid-handling twin catches? On the same 522 seeded faults it raises on 270 and the twin flags 366; everything the simulator catches the twin catches too, while tip reuse, a 5 µL dispense and a half-empty source pass the simulator. Mostly policy differences; the fault set was written for the twin (stylised).
