Modules

• 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
