Jaeyoung Lim is a software engineer in Auterion. You can find him on Github, Linkedin and Facebook.


Can you tell us the story of how you got into PX4?

I worked as an intern building a ROS based quadrotor research platform for a research lab in Seoul National University during my bachelors. This led me to realize how powerful PX4 could be as a development environment. I liked especially the offboard functionality since you can focus more on your application while PX4 can take care of the rest. 

What company do you work for and what’s your “day role”?

I work for Auterion, and my daily work revolves around working on simulation or the companion computer on the skynode. I try to enable developers to test their software changes in Software-In-The-Loop simulations.

What is your current project based on PX4?

In Auterion, we try to simulate workflows end-to-end in simulation to test our software in a safe way. Here is an example.

What is your professional and educational background?

I did a masters in mechanical engineering focusing on robotics in ETH Zurich, Switzerland.

What is your “area of expertise” within PX4?

I mainly work on simulators that are integrated into PX4. A lot of the time have been spend on gazebo, but one of the recent integrations have been done in JSBSim as shown below.

What is the most unique thing you have done in drones/robotics?

I was part of a project building a nano satellite during my bachelors. SNUSAT-1a and SNUSAT-1b have made it into orbit in 2017.

What is your current favourite setup for development kit?

For software: SITL gazebo with mavros / mavsdk

For hardware: Pixracer / Px4vision

What is your favorite book?

The Innovator’s Dilemma from Clayton Christensen.

What languages do you speak?

Korean, English.

Where are you from and where did you grow up?

I am from Seoul, South Korea. I grew up in UK and South Korea.

What advice would you give to fellow drone developers who just joined the PX4 community?

Don’t be intimidated with the complexity of drones. The community has always been the biggest helper for me. There is no reason to be shy in asking questions on the forum or joining the dev call if you need any help!
