This is the master page of all tractor development for 2018

See github page at https://github.com/skikro/microtrac for quick part download and latest versions


Basics

  • A set of hydraulically driven, versatile tractors:
    • MicroTrac, a walk-behind tractor
    • LifeTrac, a larger riding tractor
  • Easily configurable
  • Straightforward to maintain
  • Cost effective to build using the OSE Microfactory or a set of basic tools

6 - Control System

  1. Hyrdaulic control panel
  2. Electromechanical control (Arduino, remote)

Modules (Needs update)

  • GPS + Computer Vision - using standard phone gps, the tractor has a GPS unit to which the Feed Me App connects. Computer Vision helps guide the tractor.
  • Feed Me App - remote control smart phone app app combining GPS with computer vision to allow direct smart phone control,preprogrammed control, and computer vision assist which prevents the tractor from bumping into things
  • Control solenoids - connected to Arduino - these allow for automated motion of the tractor
  • Hydraulic control module - the hydraulic valves and circuit for running the tractor
  • Solar power cube - a small power cube that can run from a single power cube.
  • Power cube - the 16 hp base that is scalable and practical up to 160 hp
  • Hydraulic Reservoir module - it is the reservoir to which one can connect any number of power cubes
  • Cooler module - hydraulic fluid cooling system to itch can be attached any number of power cubes for cooling
  • Gasifier module - a gasifier burner that works with charcoal for providing fuel to the power Cube
