Introduction

After the Learning Path and Getting Started, continue by role. This chapter is a set of short learning paths: who you are, then ordered links into existing How-To, Concepts, and Reference pages.

It does not repeat the beginner day-by-day path. Task recipes stay under How-To.

Whatever role you follow, carefully learning how to use the motion-control / robot control stack (运控系统) helps later work:

• Terminology — 驱动层 ↔ Hardware Interface; 分体 / 全身; 夹爪 / 灵巧手

• ros2_control in This Stack — hardware:= and how this stack loads controllers

• FSM and Topics — /fsm_command is std_msgs/Int32

• Controllers — Basic Joint Controller, OCS2 Arm Controller, OCS2 WBC Controller; 分体 / 全身

• Hardware Interfaces — ros2_control plugins (Chinese: 驱动层)

• 分体控制 vs 全身控制

Hands-on: Use Basic Joint Controller.

Roles

Role	Start here
Field commissioning (现场调试)	Field commissioning — zip deploy, fa-py-libraries, VR teleop, Viser
Classical algorithm engineer (传统方案算法工程师)	Classical algorithm engineer — Python API for your own vision / control loop
VLA collect / train / deploy (VLA 采训推)	VLA collect / train / deploy — VR collection, whole-body + waist, force-related pages
Simulation engineer (仿真工程师)	Simulation engineer — USD / Isaac assets, robot config, action composition

How to use this chapter

1. Finish Install Environment and a first Quick Demo if you have not already.

2. Open the role page that matches your job.

3. Follow its numbered path. Each step is a link; run the procedure on that page (or the README it points to).

Public robots on this path include ARX (方舟无限) Lift 2S (full-body mobile manipulator) and Acone / AC One (dual-arm). HighTorque (高擎) Panthera HT is a dual-arm manipulator. Product how-tos: ARX Lift 2S, HighTorque Panthera HT.
