The initial goal for this project was to create a simple remote control robotic arm, capable of lifting various object. After putting some thought into the design, it was decided to use the least amount of screws possible because it would make assembling the arm much easier. Only use the screws that were provided with the servo motors were used because anyone who wanted to build the arm themselves would likely have the exact same set of screws. In the final version, a total of 12 screws were used to piece together the entire build.
