## What it is
AR2 is a DIY 6-axis desktop robot arm built from 3D-printed or machined parts, stepper motors, and an Arduino controller, together with Python control software. The repository provides CAD files, a bill of materials, an Arduino stepper driver sketch, a kinematic model, and software to program and operate the robot.

## Use cases
- build a 6 axis robot arm from 3d printed parts
- control a stepper motor robot arm with python
- program and operate a desktop industrial-style robot
- inverse kinematics for a 6 axis arm
- arduino stepper driver control for robot joints
- calibrate and jog a diy robot arm

## When to choose
- you want to build a low-cost 6-axis robot arm yourself
- you need open CAD files, firmware, and control software in one project
- you want to learn robot kinematics hands-on

## When to avoid
- you need a certified industrial robot for production use
- you want a supported, licensed product with warranty
- you need plug-and-play hardware without assembly

## Facets
- artifact type: application
- maturity: maintenance
- function: robotics, simulation, gui, developer-tools
- domain: robotics, hardware
- platform: python, cross-platform
- tags: robot-arm, 6-axis, stepper-motor, arduino, kinematics, diy-robotics, 3d-printed, automation, desktop
