TL;DR
I like to have long handed versions of fast / stack inserter and versions with diferent angles but don't like to have to much inserters at all.What ?
Reduce existing inserters to following types:- Burner inserter
(Normal) inserter
Long handed inserter
Stack inserter
- Long handed stack inserter
Full controlled robot arm (direction and long/short controlled by circuit )
This two slots can used for:
- better gearbox (speedup 1 times)
- filter (each adds 5 filter-slots)
- angle sensor (adds ability to load/unload in 90degree steps)
- maybe since 0.16 a compression upgrade may needed
Better gearbox: puting in one of them should equal current fast inserter, (The second one should increase it a bit but not as much as the firrst one). - Should also works on long arm inserter. Stack inserters should be mutch slower then in game at moment, so one gearbox should result in a stack inserter as fast as it is in 0.16. - Should not work on robot arm.
Filter: puting in on of them equals actual filter inserter. put in a second one to double up filter slots.
Angle sensor: If installed there should be 4 points (North, East, South, West ) in GUI where I can switch between input, output or nothing. Example: An inserter loading from two belts in one factory may have West and East set to input and North sets to output. On this way you can input up to 6 item types with one inserter (3 belts on W, E, S and Assembler on N) or spread one belt content over 3 destinations.
Robot arm: An inserter which have the abaility to swich between input and output mode by conditions in circiut network. And also swiches beween long-arm-handling and short-arm-handling by circuit condition. And is an fast inserter by default (therefor an extra gearbox has no benefit).
A possible use case is to have a robot-arm transfering items from chest A to chest B as long as chest A contents more than 1000 iron. If the iron contained in chest A goes below 400 the robot-arm swiches and fill iron back from chest B to chest A.
Robot arm with "angle sensor": This woud be the masterpiece of an inserter. In case of put an angle sensor in a robot-arm it should be possible to set the 3 states (input, output, none) of each direction (N, E, S, W) by circuit conditions. If you add a filter it may be the most complex (and full controllable) inserter (because filters can be seted by network too).
