Download (8Mb) Abstract In this thesis we implemented a system, which Parrot AR.Drone can use to track a moving target. The system is based on ROS. We used an iRobot Roomba as the target, put a marker on top of it, and drove it around. The drone's goal was to stay as directly as possible above the target. The drone tracked the marker using its front camera.

Its movement was controlled by PID controllers. We conducted three experiments to evaluate the system. First we evaluated how accurate our method of determining the drone's height was, compared to its default method. Then how accurately and robustly the drone can hover over a stationary target. ar drone 1 caracteristiqueLastly, we evaluated the accuracy and robustness of the drone hovering over a moving target. the best bagpipe drone reedsThe results show that our system allows the drone to hover much more reliably over the marker, compared to its default stabilization methods. parrot ar drone propeller replacementThe system also provides a better means of estimating the distance of the drone from the marker, compared to the built-in sonar. parrot ar drone for hunting

How would you like your drone to follow your red shirt, or unique glyph photo. Or maybe remote control your drone with a joystick, wii remote or voice recognition.

Even better, how cool would it be to have your drone remote controlled from another location over the internet? All of those scenarios are possible, but in this tutorial i'm going to cover the Color following ability. Below is a video that covers the next few steps.Step 1: Download EZ-Builder The software we will use to control the AR Drone is EZ-Builder.

Seydoux founded luxury goods company Christian Louboutin -- the company famous for the iconic, red-soled pumps -- a 3-D imaging company, and wireless products manufacturing company Parrot which makes everything from a self-watering flower pot to drones. With the launch of the $549 Parrot Bebop 2, the next generation of Parrot’s Bebop drone that can stay in the air twice as long as the former version, Seydoux is inching more into the drone world.

Parrot acquired commercial drone company senseFly in 2012, and launched a new lineup of $99 “MiniDrones” earlier this year to target the toy market. Parrot’s drone revenues made up 57% of the company’s revenue for the third quarter of 2015. Seydoux offered up some advice on business, investing, drones, and his biggest money mistake: MarketWatch: You’re well-known for founding Christian Louboutin, the company that makes the luxury, red-soled shoes. How do you go from selling shoes to selling drones? Henri Seydoux: Shoes were a friendship. Christian Louboutin (the designer behind the company) was a friend. With drones, it’s a completely different market, but in the end, they’re consumer products. You’re selling an end-product to a user, and I’m always trying to find innovative products. Christian Louboutin shoes at the Design Museum. Henri Seydoux is co-founder and director of the company. MarketWatch: From shoes to headphones to drones, you’ve been involved in lots of products.

Which is your favorite? Seydoux: They are all my babies. You’re asking me to choose my favorite child. I have no favorite. When I make products, they’re all directly created for the customers. MarketWatch: What’s the biggest money mistake you’ve ever made? Seydoux: When I spend money, I like art. I have plenty of paintings, and I don’t know where to put them, but then sometimes I buy paintings that I later regret. MarketWatch: What’s your biggest challenge as an investor? Seydoux: My biggest challenge is just finding that good idea and to launch it. The idea has to live by itself. I always look at the innovation and whether I’ve seen it before. It’s always about the first impression. MarketWatch: [Parrot] was really the first company to manufacture consumer-oriented, ready-to-fly drones. What struck you about the idea of manufacturing drones? Seydoux: It was really about the idea that you can turn telecoms into toys. Ten years ago it would be crazy to have a camera on a phone, and the first cameras were so bad.
