# #1: Femto (DIY kit)
|
|
|
|
## + Features
|
|
- Bolt-on module to a DIY barn/pen; will support salatin-style tractors
|
|
- Automation that's fit for leaving for a weekend
|
|
- Mounting for water tank (as ballast)
|
|
|
|
## ? How
|
|
- Basic automation of movement
|
|
- Timer-based?
|
|
- Odometry?
|
|
- Basic automation of steering
|
|
- Set-it-and-forget-it ...
|
|
- "Manual vision" (networked camera for aiming, manually pick a target)
|
|
- Coulters?
|
|
- Corn/row crop feelers?
|
|
- Mounting for water
|
|
- Solar panel, charger, onboard battery
|
|
- Pushbutton / LCD interface on-device
|
|
- Slow-mode manual vision
|
|
|
|
## - Probable Limitations
|
|
- No auto-turn-around
|
|
|
|
## ! Problems
|
|
- Balance of the barn
|
|
- Front-end 'mow through' ability
|
|
-
|
|
|
|

|
|
|
|
8hr sit down and make the perfect design from scratch
|
|
16hr find the best components
|
|
8hr dfm that shit and make drawings
|
|
16hr build the thing, $1000 of materials
|
|
2hr install that shit
|
|
|
|
-> 1st prototype in 50hr + $1k
|
|
|
|
5hr go back to the drawing board again and fix it
|
|
5hr dfm the hell out of it
|
|
16hr build the thing again
|
|
|
|
-> 2nd prototype in 24hr + $600
|
|
|
|
16hr design the awesome control board bang it out in kicad
|
|
5hr agonize over the control box
|
|
8hr build it all
|
|
|
|
-> 1st electrical prototype in 30hr + $500

# Steering
|
|
Ways to do steering:
|
|
- Vision: drive towards a flag / pole
|
|
- Vision: drive towards ground markers
|
|
- Vision: drive along a painted line
|
|
- Vision: drive along a mowed path *so much SWE effort...*
|
|
- "Corn head" feelers (can this work in a broadacre setup somehow?)
|
|
- Taut tether
|
|
- Wheel encoder feedback
|
|
- Dig a trench
|
|
- TOF Triangulation
|
|
- GPS / RTK *can you set up your own RTK base station? Probably. *
|
|
- Follow a buried wire
|
|
- Coulters / stabilizer wheels
|
|
- Coulters *with pressure sensors*
|
|
- Ridge-till
|

|
|
|
Remember you're only using steering a small portion of the time. You *could* use a floodlight in conjunction with retroreflective tape.
|
|
|
|
This should be non-obnoxious though.
|
|
# Telemetry
|
|
- Why have telemetry? Lets you know if the barn is stuck. Lets you force a move. Maybe you want cameras?
|
|
- Need long range, but not a lot of bandwidth (unless you want video)
|
|
- WiFi isn't the right solution for this, LoRa is
|
|
- Have a LoRa base-station in your office/shed... this could be an internet gateway or a PC-link...
|
|
# Hold the presses. Stop it all. Everything.
|
|
|
|
Make a walker.
|
|
|
|
Lots of advantages. So many
|
|
Big problem is how do you turnaround / tow it
|
|
And maybe the answer there is "tow it" for the farmer but not for the homesteader
|
|
_omnidirectional walking mechanism?_
|
|
|
|
hey lol remember the _screw drive?_ The one Fordson made. Maybe for the nano |
