A simple desktop robot arm using typical 9g microservos.

**Height:** 280mm

**Base width:** 120mm

**Reach:** 160mm


BOM
----

Bill of materials for building the robot arm.

- 230g of filament
- 6x 9g microservos
- 5x servo cable extenders
- arduino with 7 servo pins (I used a mega)
- raspberry pi (or similar)
- usb power supply
- 3mm ball bearings


Build Instructions
---

1. Print out all parts (base, base-joint, arm-joint, arm-joint-2, arm-joint-3)
2. Clear out servo-cable holes with some kind of metal pick
3. Screw servos into servo spots
4. Screw servo horns into servo-horn spots
5. Plug servos into arduino, set their positions to be half-range
6. Press base-joint servo horn into base servo gear, use long screwdriver to attach
7. Press other joint servo horns into their servo gears, screw in
8. Attach servo cable extenders to servos far from the base
9. Ho
