Recharge your drone at my place

Posted on February 4, 2016 at 8:02am 9 Comments

Does anybody want to move in next door? We could send drones to each other ad infinitum. :) I cannot confirm if this installation increases/decreases the value of your home. 

This test represents an interesting combination of products and technology from 3DR,…

Copter Localization w/ IR Landmark

Posted on January 9, 2016 at 9:27am 18 Comments

The video shows localization data collected during a short flight over an IR marker, which is used to estimate the relative location of the copter with respect to the visual landmark. Note that this was a manually flown flight, but the ultimate goal is automation. Detecting visual landmarks/features is a fundamental task in many forms of…

Automated Precision Landing on a (stationary) Boat

Posted on October 29, 2015 at 9:37am 2 Comments

How many copters did we sink? :) Check the video above. The development of Precision Landing hardware and software has progressed since our last blog post. The existing controls code has been added to master in APM:Copter (i.e., V3.4-dev). The two demo videos included in this post were produced with a modified version of APM:Copter V3.3 (similar to the master code).…

SOLO Smart Drone lands smartly :)

Posted on September 8, 2015 at 12:10pm 8 Comments

Warning: I think this voids your warranty. :) We integrated an IR-LOCK sensor with a 3DR SOLO. This project was mostly for fun, so don't read too much into the flight performance shown in the video. We only had one test session, and we didn't tune any parameters. 

You might notice that the flight…

Landing on your back porch? In close proximity to trees? And near your grandmother? :) 

We produced documentation regarding the 'Precision Landing' developments (link). The primary intent of this development is to enable more industrial use-cases for multi-copters, namely, fully automated systems with auto…

Thank you for the undeserved compliment. :) 

You can control missions with your laptop. If you read through the wiki, I am pretty sure you will find what you are looking for.

You can connect to your laptop with a 3DR Radio.
