We will try to keep the tutorials brief, most of you all are mechanically inclined to some degree. If you need additional support, please discuss on the specific topic you are having troubles with!
There are 2 major components to the servo motor assembly:
- Servo Motor Edge Cards
- Mini Breadboard Acrylic Card.
Servo Motor Edge Cards
The servo motor frame assembly is where all 5 flexion servo motors are housed. The servo motors have metal gears and relatively robust (Part #MG996R). For each servo motor, we have TWO 3D-printed parts that we need to attach.
Here is an example of what we are trying to achieve: Here are the steps:
- Servo motor edge card (this is what we are calling it)
- Servo motor spool (*the picture shows a previous iteration, we've since altered the design slightly)
1. Gather all of the parts that you will need to install one servo motor gear. Each servo motor includes an array of screws, servo horns and miscellaneous hardware. You will need:
Take the servo edge card and feed it behind the servo motor:
- 4x silver screws (phillips head)
- 1x servo motor (MG996R)
- 1x servo card
- 1x spool
- 1x servo motor ROUND horn
- 1x black screw.
3. Carefully place the lower end of the edge card over the servo motor wires:
4. Push the top edge of the servo card to make sure it is flush with the servo motor:
5. Find 2x silver screws and install it diagonally on the edge card. *There will be some resistance when trying to screw the silver screws into the edge card. PLEASE ENSURE that you are using the correct phillips screwdriver, otherwise YOU will strip out the head. There is no need for four screws, we will use the other 2 screws for the spool!
6. Now we need to install the 3D printed spool onto the round servo horn. This is a little difficult, we included a mini tool to help install the spool onto the horn! You will need the last 2 silver screws. Line up the rounded spool so that the center holes line up to the 3D printed part.
7. From the other side, screw the silver screws into the black rounded servo horn. The screws will stick out, but you will not be able to see them from the front. The included tools holds the back of the servo horn while applying force to make your life easier! *There will be some resistance when trying to screw the silver screws into the edge card. PLEASE ENSURE that you are using the correct phillips screwdriver, otherwise YOU will strip out the head.
8. Place the 3D printed gear + servo horn onto the servo motor. *WARNING, do not manually force the motor to move. Use the black screw that was provided and screw it in after the 3D printed gear + servo horn is on the servo motor.
9. Repeat these steps for the rest of the servo motors.
10. Place the servo motors with edge cards into the servo motor frame (such that MG 996R is upside down):
