Jaeryoung Choi, Soomin Lee, Dongho Kang, Jaeyoung Lim This project was done during Virtual Reality 1 course held in spring 2017 ETH Zurich Overview Project ICARUS is a virtual reality flight simulator which the user stays in the air by pedaling the bike. For more information, you can visit the ICARUS Project Github Demo day…
Jaeyoung Lim This post is written with the work done with Modulabs DCU Lab Introduction Implementing a onboard computer on a small UAS can have many benefits such as being able to use ROS onboard the system. This can speed up the development process and enable to use various sensors and actuators that are supported…
Jaeyoung Lim Currently ROSPPM is in a development stage and at times may not work properly. Please let us know what problem you are experiencing through issues in the [repository](https://github.com/Jaeyoung-Lim/rosppm) Introduction RC Transmitters are used to control miniature cars and planes for a long time. Although the technology has evolved quite a long way, RC…
Jaeyoung Lim Introduction PX4 is a great platform to implement a UAV system based on a opensource autopilot. One of the great features of PX4 is that you can run a SITL simulation(Software in the loop simulation) to simulate your flight on simulation. This is useful as you can check new mission or control algorithms…
Jaeyoung Lim Overview A USB2PPM interface was developed which enables a PC to interact directly with the RC transmitter trainer port. External Position Control was successfully demonstrated to show that the computer can successfully control real-time applications using the USB2PPM controller. This can be used for sending simple data in long distances (~2km) in a…
In this project, I’m making a Tablet PC with a Raspberry Pi with Raspbian and a LCD Touchscreen display. I bought a LCD Touchscreen from chalkboard electronics. Before designing the tablet, I had to set up the touchscreen. The biggest problem that I had was the power output of Raspberry Pi’s USB was smaller than…
This is a “Sound Visualizer”. I made this program for fun using Max MSP and Processing. Max MSP detects the sound and Processing draws some cool graphics. Enjoy the Video! Features – Sound Visualizer is consist of two programs : Mixer, Sound Visualizer. – You can set up Threshold from Mixer : Sound Threshold and Line in Threshold. – It…
This post is written by Jaeyoung Lim Overview Recently opensource autopilots have become reliable by various failsafe functions integrated by the opensource community. Developing different softwares for each application can be time consuming and hard to verify the reliablility of the software. An alternative to modifying the autopilot software, is to use an onboard computer…
This project started out as an experiment. The idea was that standard flight controllers should be able to control non-planar shaped quadrotors as long as the control board is mounted near the center of gravity. I decided to try the idea out. The project addresses the symmteric / non-symmetric forms of non-planar motor layouts. Basic…
