The aim of this task is to contribute in the printing and implementing of a human size robot, Cooperating in this long going joint project to assemble the primary open source 3D printed life size robot. The goal was to manufacture and build this robot while figuring out how to print with 3D printers. 3D printing is an additive manufacturing method that can build objects directly from a computational model. Unlike traditional manufacturing methods such as milling and molding. 3D printing technology consists of a set of technologies operating on a similar principle of adding material in successive layers. Some common 3D printing technologies include FDM, SLA, SLS, DMLS, etc. But the most widely used and the type we used to build this project is a process known as Fused Deposition Modeling (FDM). All the downloadable parts from the official InMoov website were ( 211 ) parts only to build the upper body of the humanoid robot. But we only have built ( 81 ) parts from the total parts of the project to build only the right arm of the humanoid robot. It is essential that one considers some parameters though that you can specify in every software of a 3D printer, and that you need to be aware of in order to print the pieces correctly and be sure that they won't break down while the robot is functioning.
