External Position Control of a Quadrotor Using USB2PPM

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…

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…

Non-Symmetric Non-Planar Quadrotor

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…

APM Quadcopter Autonomous Flight

I and my friend Jaeyoung tested GPS Autonomous flight mode of APM with two quadcopters which embed APM boards.

One embed APM 2.6 board and another embed Pixhawk board. Both uses ArduCopter firmware. A mission of Auto-flight is taking off from launch site – moving to waypoint – hovering for 2 minutes – returning to launch site.
