Knee or mecanic elbow

The overall project is to make a robot about 75cm tall. To begin, I identified 2 types of movement for all joints (other than eyes and hands). This part of the project is for joints such as elbows and knees.

The elongated rectangular parts will serve as framework and parts to "attach" the visual appearance of the robot. The frame will also serve to guide the wires so that they are visible as little as possible.


Printed parts:
   - 1x Knee-A: Supports both one of the gears and the servo motor
   - 1x Knee-B: Gear for transmitting maximum force from the servo motor
   - 2x Knee-C-2X: Supports bearings to reduce energy loss through friction
   - 1x Knee-D1 and 1x Knee-D2: Non-identical parts to create the gear for receiving the rotation
   - 2x Knee-E: 2-piece2 axle between the bearings and the wheel of reception
   - 1x Knee-F: Any receiving bone adapted to change as needed

Non-printed parts:

   - 1x SG90 servo motor
   - 2x Bearing 8x12x3.5
   - 8x M2.5 8mm screws
