If the person being fed leans toward the spoon, can a blind feeding arm do without a camera?
research/osrobot-lean
If the person being fed leans toward the spoon, can a blind feeding arm do without a camera? At 30 mm sway and 0.20 m/s the blind arm's safe share rises from 0.21 to 1.00 as the lean reaches 100 mm/s (stylised; extends osrobot-assist).
What it found
A stdlib extension of osrobot-assist's planar feeding-arm twin in which the user shifts the mouth toward the spoon tip at a swept lean speed (200 paired trials per row). At 30 mm sway and 0.20 m/s the blind arm's share of feeds with peak lip force at most 2 N rises from 0.21 (passive user) to 0.69 at 50 mm/s and 1.00 at 100 mm/s, against 0.71 to 0.97 for the camera arm; at 50 mm sway even 100 mm/s gives only 0.62 for the blind arm. Leaning removes contacts but not the peak force of the ones that remain (4.0 N at 0.20 m/s). Stylised: every constant, including the lean speed, is assumed; no person was modelled or tested.

- When a pest window sets a deadline, is a scout-and-treater fleet or a fleet of inline weeding robots cheaper?When a pest window sets a deadline, is a scout-and-treater fleet or inline weeding robots cheaper? One scout cannot finish 16 fields faster than 5.3 to 32.5 h; pipeline/inline cost is 1.06 to 1.12 at 0.72 ha, 1.49 at 0.18 ha, and 0.87 to 0.93 at 1.62 ha where it can meet the deadline.
- If one scout drone feeds ground treaters in a pipeline, can a held fleet beat inline weeding robots?If one scout drone feeds ground treaters in a pipeline, can a held fleet beat inline weeding robots? One scout keeps only 1.0 to 1.3 treaters busy; overlapping the stages cuts the held-pair penalty to 1.04 at 0.72 ha fields and 0.86 at 1.62 ha, still losing on small fields. Assumed prices; scheduling over
osrobot-pairprice's fits. - Is a scout drone plus a camera-less ground treater cheaper per hectare than one weeding robot, and from what field size?Is a scout drone plus a camera-less ground treater cheaper per hectare than one weeding robot? With assumed prices and each machine charged for its own minutes, break-even is near 0.5 ha and the pair is about 0.7 times the cost per hectare at 5 ha; held for the whole job it never wins; flips with utilisation, labour and battery life. Stylised, nothing built.
- Does a fast scout platform plus a ground treater beat one weeding robot, and does a mud-aware tour matter?Does a fast scout platform plus a ground treater beat one weeding robot? At matched kill (0.343) a 3 m scout swath finishes in 26.6 min against about 42 min for one inline robot, but a 1 m swath takes 47.3 min; a mud-aware tour changes nothing (stylised, simulation only).
- Does a better tour rescue scout-then-treat weeding?Does a better tour rescue scout-then-treat weeding? 2-opt cuts the tour from 539 m to 468 m but a field still takes 56.1 min against 51.7 min treating inline; scouting loses at every weed density tried (stylised, simulation only).
- For a weeding robot with a cheap camera, is it better to treat weeds as it drives or to scout first and come back, and what does a weak sensor cost?For a weeding robot with a cheap camera, is it better to treat weeds as it drives or to scout first? Scouting then touring killed the same share (0.399 against 0.401 at 1 m/s) and was slower in all 23 paired rows; lane overlap repays a weak sensor (0.40 to 0.86 killed) at 3.5 times the time. Stylised, constants assumed.
