### 3D Printed Servo Robot Micro Arm

#### Parts used:
- Arduino UNO
- MG996R Servo
- 3x SG90 9g Servo

#### Instructions:
All servos are screwed into the corresponding holes on each part.
Servo Horns are also screwed into their corresponding positions.
Each part with a servo horn is attached to the servos.
Cables are routed through the different pieces and come out from the bottom.
Covers are screwed on with the same screws that are used for the servos.

#### Power
Make sure the servos are powered from a separate supply and not the Arduino directly.
They draw a lot of current and can often drop the voltage on the Arduino when moving resulting in it powering off. I recommend overvolting the servo supply slightly to 5.5-6V for better movement.
