What you will gain after the course

  • Structural thinking capabilities in overall robotics H/W and S/W: A clear understanding of the role distribution and mechanisms between High-Level Controllers (HLC) and Low-Level Controllers (LLC)

  • Robot internal data flow design and analysis skills: Analyze the differences between core robot internal communication standards such as CAN, Ethernet, and EtherCAT, and master the packet paths through which sensor data and control commands travel.

  • Practical Robotics and Interview Readiness: The ability to provide a structured interview response that fluently explains the "entire process from a user's command to the robot's movement" from the perspectives of sensors, communication, control, and motors.

  • Understand employment and career change trends at a glance with this collection of the latest domestic and international robotics job descriptions (JDs).

Developers who want to understand the entire robot system as well as their own area of expertise


What will you learn and gain after taking this course?

  • Robotics System Design Capability: The vision to design the entire H/W and S/W architecture

  • Robot internal data flow design and analysis capabilities: Mastering core internal robot communications such as CAN, Ethernet, and EtherCAT

  • Robotics Practical Interview Readiness: The ability to provide structured and in-depth answers that persuade interviewers

  • Identify the technology stacks and competencies desired by global corporations : Providing a collection of the latest domestic and international robotics job descriptions (JD)

Features of this course

  • Sharing practical design methods and troubleshooting know-how used in the field, rather than just listing simple theories

  • Mastering core robotics components (HLC/LLC/Motor/Lidar) and communication (CAN/Ethernet/EtherCAT)

  • Analysis of the actual autonomous robot 'Unitree Go2': Even if the appearance and form of robots differ, the core components and communication architectures used inside are similar.

The person who created this lecture

"Real know-how gained from rolling and crashing through everything from the bottom of HW to SW"

Hello, I am a current robotics developer at a global corporation.

Having worked in the robotics industry for several years, I have experienced everything from the lowest levels of HW to the highest levels of SW.

This course is not an academic textbook full of grand theories. I am creating this course to organize the know-how I have fiercely accumulated in the field, while also earning some side income.

If you have any questions about the lecture, please feel free to leave a comment at any time. I will help you gain so much that you won't feel the cost of the lecture was a waste!


Do you have any questions?

Q. Can I take the course even if I don't have the actual hardware or robot parts?

A. Yes, it is absolutely possible! This course is not about soldering specific hardware or typing code line by line. It focuses on understanding the 'structure and architecture' of how data flows within a robot and how components interact organically, by benchmarking the actual system configuration of the high-performance autonomous robot, Unitree Go2. Since the course centers on concepts and principles, you can be fully immersed in learning with just a computer, even without physical equipment.

Q. I am not a robotics major or I am a developer in another field; will I be able to follow along?

A. The difficulty level is designed so that anyone who has heard basic terms such as embedded systems, embedded communication (UART, CAN), or MCU at least once can take the course. Since I explain in simple terms how various fields of knowledge—such as mechanical design, electromagnetics, and computer science—interlock and function together within the complex entity of a robot, it will serve as the perfect introductory compass for those considering a career change or expansion into the robotics field from other domains.

Q. Will taking this course provide practical help for interviews or employment?

A. This is not just knowledge for simple theoretical memorization. In the final section of the course, based on actual interview questions for experienced robot developers, I provide close guidance on how to logically explain the entire data pipeline flow—from sensors and communication to control and motors—to an interviewer. You will be able to leave a strong impression on the interviewer that "this candidate is not just a fragmented coder who only knows their own field, but a prepared architect who can immediately and proactively collaborate with all the mechanical, electronic, and software engineers on our team!"

Notes before taking the course

Practice Environment

  • Operating System and Version (OS): As this is a concept-oriented theory and architecture analysis lecture, it can be viewed regardless of the OS, such as Windows, macOS, or Linux.

  • Tools Used: This is a knowledge-based class that does not require the purchase of any separate paid software or hardware equipment.

Prerequisites and Important Notes

  • Prerequisite Knowledge: Having very basic embedded knowledge of computer architecture, MCUs, and communication will make it much easier to fully absorb 100% of the lecture.

  • Copyright Notice: The intellectual property rights for this lecture and all provided teaching materials belong to the instructor. Unauthorized reproduction, distribution, or sharing may result in legal liability. If you have any questions during the course, please leave them on the Q&A board, and I will answer them from a professional's perspective!

Who is this course right for?

  • Job seekers and students who are interested in robotics development roles but feel overwhelmed about how to get started.

  • A junior developer who wants to quickly adapt to their work by gaining an overall understanding of robotics systems.

  • Developers who want to understand the entire robot system as well as their own area of expertise

Need to know before starting?

  • Mindset: Rather than the skill of writing a single line of code, you need a sense of inquiry to grasp the big picture of the entire robot architecture.

  • Having a very basic knowledge of embedded systems, such as computer architecture, MCUs, and communication, will make it much easier to fully absorb the lecture.
