Current Status - Farmbot construction is 90% complete. Tool holders need to be mounted, Vacuum and water inputs need to be hooked up. Farmbot is alive and moving. Controllable from laptop access.
Northeastern Wisconsin Technical College's (NWTC) Capstone courses will be building at least 3 Farmbot units in the next few years. These bots will be used to create a partnership between very different fields of study on campus. These fields include, but are by no means limited to Automation Engineering Technology, Electromechanical Engineering Technology, Agricultural Studies, Prototype and Design Studies, CNC, Machine Fabrication, Electronics, and Sustainable Energy.
For our first build, we will be using open source materials to create a standard 1.5m by 3m Farmbot on a lumber sub-assembly that can be transported to a final destination when complete. Future plans involve building and donating Farmbots to The Farmory in Green Bay, Wisconsin. The Farmory uses aquaponics to produce quality fresh foods for people of low income communities.
This page will be updated throughout the Fall semester, 2016 and then handed off to the next class if they wish to continue documentation.
We meet once a week for 6 hours for this Capstone course. We do work on other things in addition to the Farmbot, but most of our time is devoted to this project.

* Drill pressed the holes on the plates since the water jet did not cut them in a complete circle motion and it left a little sliver that prevented the screws from fitting through
Day 4: September 22nd, 2016
*The main BOM didnt list all parts needed-instead they were in “fine print” saying they go with parts listed on the main BOM. So we had to go through the sub assemblies and make sure we had all the extra stuff. Found that part names were different. Documentation on Farmbot page lacks consistency with naming.
Day 5: September 29th, 2016
* Electronic mount did not fit in the electrical box once the electronics were mounted-had to make the screw holes into slots to allow us to move the electronics over as needed to make it fit.

Documentation will be uploaded as we tidy up the project.
Stepper Motors - We used Dual Shafted stepper motors and tapped the plate on the shorter shaft end to hold the encoders. Below is the basic wiring for the power connections. No wiring diagram yet available for the encoders, as we have not figured it out yet.
