Abstract [en]

Industrial AGVs have become very extensive in today’s market but the problem every small-scale industry faces is the cost of the AGV or similar robots for transportation and storage. The study aims to develop a methodology to provide robots at a cheaper rate and make them available to everyone with 3D printing technology and an open-source program. The study can potentially change the industry standards if it succeeds and can provide AGVs at phenomenally cheap rates but the first few generations will have marginal disadvantages. The research focuses mainly on the two research questions, is it possible to make an AGV completely with 3D printing and open-source hardware? Is the AGV made with 3D printing possible to carry a weight of (300kg)? To approach these research questions a literature survey has been done and based on that the methodology has been developed which includes designing the AGV with material selected polycarbonate, which is the strongest 3D printing material. The AGV designed in CATIA is simulated in Fusion 360 with a steady load acting on the top with a magnitude of 390 kg. The simulation resulted in a deformation of 17.3 mm in the Y axis which indicates that the material undergoes deformation when the load is acting upon it. It can also be hypothetically concluded that when other forces like sheer and tension act on the body, the materials undergo more structural deformation which hinders the working of the product. A solution has been suggested and studied with 3 steel shafts reinforced under the top cover, which itself is made of steel, and the results indicated the AGV can withstand a load of 300 kg with no sign of deformation. An alternative study conducted included a top cover with a thickness 10 times more than previous studies and proven effective. The significance of the study is to provide cost-effective methods for the production of AGV with 3D printed materials and open-source software and hardware which can accessed by everyone without paying millions.
