I designed the rotating base of the arm with screw holes to mount each servo and connected this to a planetary gearbox with a 4:1 transmission ratio so that the first axis is able to have 120kg.cm of torque. Doing this means that it will be more accurate and precise and that the servo will be under less stress and will run at lower temperatures. I also designed the base frame which the servo sits in which has a nice pattern that i named the arm after. I finished by creating the brackets for the planetary gearbox and servo to be connected to the base frame, then recorded all the different parts needed for the robotic arm and completed the design stage.
