Field hand

Field hand

This mechanical hand replacement is made to speed up the sowing and harvesting tasks of a farmer. Multiple telescoping finger-like protrusions can simultaneously harvest from several points on the same plant, or precisely sow several holes at once. It also has a general-purpose manipulator. It is somewhat ungainly, which slows down movement slightly.

The field hand is an artificial body part that provides both the functionality of a normal hand, while also increasing Plant work speed by 160% and inflicting a -8% Moving penalty.

This is a hand replacement, and cannot be installed in a bionic or archotech arm.

Acquisition

Field hands can be made at a machining table once Specialized Limbs has been researched. Crafting one requires Steel 60 Steel, Component 8 Components, 15,000 ticks (4.17 mins) of work and a crafting skill of 5.

They can also be bought from Outlanders and Empire settlements.

Installation

Installing the part requires 2,500 ticks (41.67 secs) of work, ?x medicine of ?? quality or better, and a Medical skill of 4.

Removing the part requires ? of work, ?x medicine of ?? quality or better, and a Medical skill of ?.

If the operation fails, the part has a chance[What Chance?] to be destroyed.

Analysis

It's a niche hand replacement that is good for pawns that spend most of their time growing. The effect is especially potent for pawns with traits that modify global work speed, as the +160% bonus is added before multiplicative modifiers.

Total plant work speed is calculated as

(100% + additive modifiers) x Plant work speed skill modifier x manipulation x max(100%, 100% + (Sight - 100%) x 30%) x Global Work Speed

Harvest yield is calculated as

(100% + additive modifiers) x Plant Harvest Yield skill modifier x (100% + (Manipulation - 100%) x 30%) x max(100%, 100% + (Sight - 100%) x 20%)

The effective plant work speed (yield per unit time spent working) is equal to the product of the work speed and the yield. As a result, compared to an unmodified, healthy human, one equipped with two bionic arms will have an effective work speed that is 73% faster, one with a bionic arm and a field hand one that is 249% faster, and one with two field hands one that is 320% faster. In my opinion, field hand plus bionic arm is the better solution than two field hands. It is only 20% faster, and the additional manipulation and reduced speed penalty will make the pawn more useful for non-plant-related tasks. However, this does have the be weighted against the fact that a bionic arm is significantly more expensive than a field hand. The below table details the calculation, assuming a healthy pawn working in the light at 100% global work speed.

The drill arm, a mining-oriented counterpart, has the same behaviour in terms of bonus speed calculation. However, the effective speed calculation for resource gathering is slightly different, due to the different mining yield skill curve, and mining yield being capped at 125%.

Unless replacing a missing or wooden hand, the field hand does not improve manipulation and thus has no effect on Plant Harvest Yield. A colonist with a bionic arm, by comparison, will spend more time per plant but generate slightly more output with each harvest.

The moving penalty predominately slows move speed but also decreases melee dodge chance and hunting stealth. Note that move speed calculation applies penalties from armor before the scaling to moving capacity - so while an otherwise unencumbered dual-field handed pawn will be 0.74c/s slower than a regular unencumbered pawn, the field handed pawn in cataphract armor will only be 0.61c/s slower than an cataphract-suited unmodified pawn. That is, the qualitative 16% reduction in move speed is maintained, so the larger the move speed penalty, the closer modified and unmodified pawns become quantitatively.

Combat

Its attacks have 13% AP and 4.50 DPS.
