Posted by Gary H. Lucas . The following description was provided: ================================================================= The attached pictures are of the 'Growbot' greenhouse watering and chemical spraying machines we are building. I personally did all of the mechanical and electrical design, BOMs, Purchase orders, made some of the parts, did all of the assembly and wiring, and I hold two patents on the concept. The machine waters and sprays large commercial greenhouse up to 150,000 square feet per machine. This version has a hose reel to feed hose and power cord to the moving "Spraycar" that carries the water and spray booms down each bay. The hosereel is mounted on the "Carrier" a machine which delivers the Spraycar from house to house automatically. The Carrier and Spraycar are each controlled by PLCs (programmable logic controllers) and the user interface and inteligence is provided by a waterproof refrigerated sunlight viewable touch screen PC running Windows 98. I wrote the program logic specifications but the actual programming was done in Visual Basic by someone else. Several off the shelf 3rd party DLLs were used to do the communications and user interface.
