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…

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.

Constant Yaw Rate Quadrotor

A new flight mode was implemented on to the modified Arducopter firmware that is capable of maintaining constant yaw rate while the quadrotor is able to be controlled by the pilot in respect to the inertial frame. Such a flight mode can be used in localization applications (SLAM) or imaging. Sensors that have a narrow…

First-Person-View Quadrotor for Teleoperation

Recent attention to FPV racing and FPV experience shows that visual feedback from a teleoperated platform can give a very immersive experience. A FPV quadrotor platform was built to try the FPV experience and the results was satisfying. Visual Feedback is done using a video telemetry on 5.8GHz band. APM 2.7 ruuning Arducopter was used…
