Knee or mecanic elbow (Compact model) by routex

Last crawled date: 3 years ago

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 compact model of elbows and knees. https://www.thingiverse.com/thing:3091483 was my original, but I need save space on some parts of the body.
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 Compact-Rotate-A: Servo motor supports
1x Compact-Rotate-B: Supports bearings to reduce energy loss through friction
1x Compact-Rotate-C1: Supports bearings to reduce energy loss through friction
1x Compact-Rotate-C2: Receive servo motor movement
1x Compact-Rotate-D: Any receiving bone adapted to change as needed
Non-printed parts:
1x SG90 servo motor
1x Bearing 8x12x3.5
4x M2.5 8mm screws
3x M2.5 nuts
Steps:
1 - Put a small white piece supplied with the servo motor to insert it into the "Compact-Rotate-C2" piece
2 - Insert nuts in completes spaces for nuts in "Compact-Rotate-C1" and "Compact-Rotate-C2"
3 - Slide the "Compact-Rotate-C1" and "Compact-Rotate-C2" pieces into the slot of the "Compact-Rotate-D" and screew them
4 - Insert the bearing and one nut in the "Compact-Rotate-B" piece
5 - Srew pieces "Compact-Rotate-A" and "Compact-Rotate-B" together
6 - Insert the round end of the "Compact-Rotate-C1" parts into the bearing
7 - Insert carfully servo motor in "Compact-Rotate-A" piece and the little white piece
8 - Screw servo motor in "Compact-Rotate-A" piece
