Self-assembling multi-copter demonstrates networked flight control

 

As the united band of robots hovers and climbs off the ground, each robot module is using inertial sensors to detect tilt and roll.

Researchers at ETH Zurich have demonstrated an amazing capability for small…

Arducopter HEX with round arm replacement, UPDATE: It Flies!!

In my last post, I mentioned that I was working on replacing the square aluminum arms with round carbon fiber ones.  I am back to say that it works!

I was having a little trouble with the PDB, but I finally figured out how to get all of the cabling into the body without leaving cable…

Control an ESC (via Adafruit PWM) using a DSMX Receiver with RPi GPIO

My previous post was about how to receive serial signal data from a (pre-bound) SPM9645 remote receiver with RPi's GPIO. Now I will show you how to control an ESC based on the received remote control data using an Adafruit 16-Channel 12-bit PWM driver. Maybe this information can be useful to you or it can save you some time. I am happy for…

Arducopter 3.0 TradHeli Demonstration

I've been working on testing and making a few changes to AC3.0 lately, and did a whole bunch of test flights today which went very well. AC3.0 is simply amazing, and there's more good things to come, including a real acro mode that myself, Leonard and few other people have been working on.  Hopefully it should be released in 3.1, along with the changes I'm making to the…

Arducopter Quad-C Frame and Electronics CAD

While working on my Tiltrotor project I had a need to have CAD files of the Arducopter.  Since I could not find a good source for these I ordered the Arducopter and CAD'd them all in Autodesk Inventor and put them on GrabCad here:  http://grabcad.com/library/3dr-arducopter-quad-c-frame-and-electronics-1  I was going to do all the Electrical wiring too, but time got away from me and I…

Temperature Changes Can Cause Uncontrolled Roll

Short Story:

As this video shows the APM gyro is sensitive to heat changes after it is powered on. Be careful that you allow your APM to acclimate to the flying conditions before powering it up for the first time. This doesn’t seem to take more than 5 minutes but this is only for my specific quad…

SmartAP is fully autonomous autopilot

Now SmartAP Autopilot is a fully autonomous autopilot. In this video a quadcopter equipped with SmartAP Autopilot performs autonomous take off and waypoint flight. After that it returns to home and demonstrates an autonomous landing.

More information about the project you can find on the website:…

APM anti-vibration floating plate

It looks nice, so I hope it does the job :-)

Its effectively a floating plate on specific anti-vibration grommets.  The APM then sits on anti-vibration pads.

The jDrones telemetry expansion board is also mounted onto this plate for its close proximity to the APM.

The plates are made…

Successful Failsafe and Full Telemetry Control!

After flying 15 missions and traveling over 150km to establish the APM's reliability, I completed this final test of key failsafe and telemetry control functionality.

Specifically, I proved the APM and Raptor's ability to:

1. Conduct an unlimited loiter at the end of a mission

2. Changing altitude, throttle rate and…

Arducopter HEX with round arm replacement

After reading another conversation here about adding round tube arms to an Arducopter, it got me thinking: first, can I non-destructively accomplish this, and second what would be the impact to its weight and flight abilities.

I began by finding some round arms and mounts that might…

"DJI censoring where you can fly" (no Tiananmen Square)

According to this RCGroups post:

The WKM upgrade now has a no fly zone built into it 15km around Tienanmen Square . I love the idea of being able to impose your own no fly zones through software,for safety reasons, airports etc. I not not think it right that govts can now…

New SplineNav Version 0.2 on a 63 km/h Tour of Chinese Lotus Pond



I've now finished coding up SplineNav version 0.2. It's almost a complete rewrite from version 0.1. Besides flying smoother and using processor resources more efficiently, it now restricts maximum speed to prevent lag. For example, if you're flying fast into a strong headwind, then altitude may…
