#### Introducing SO-ARM

The **SO-ARM** is a low-cost, dual-arm teleoperation system built around a simple “leader–follower” concept:

* **Leader Arm:** Hand-held or gantry-mounted, this arm’s servos report each joint’s exact position in real time.
* **Follower Arm:** The servos mirror the leader’s joint angles instantly what you do with the leader, the follower reproduces exactly.

Beyond basic teleoperation, the SO-ARM platform is designed for ongoing “training” and refinement:

* Demonstration Recording & Playback,Imitation & Reinforcement Learning, Continuous Improvement Loop, etc.

The opportunities are endless!

## Before you get started, know your kit!

Assembled kit will have a fully assembled leader and follower arm as shown in [this picture](/partabot/so-arm101/assembled-kit-pictures.md).
