Just beginning the start of the control library More to come soon. If you are interested in seeing some demo videos, check out the You need to install the h264 (for video conversion) jar locally. You can use the Or - If you don't really care about the vision stuff and you just want toGo ahead clone the project and remove them from them from the project.clj You will also need to create a /logs directory in the root of your project Sample Usage - Drone Takes off for 10 seconds and then lands The movement commands take argument from 0-1 The fly command takes arguments left-right tilt, front-back tilt, vertical speed, angular speed.

The arguments are all in the range -1 The drone-do-for command does a command for x second The drone reset-watchdog command is used for when the drone command sequence number gets out of sync. It will ignore commands that come in with a bad or out of sync sequence number. Calling this resets it to zero. The drone will drop it's connection and reset its counter to 0 by itself if no command is received from the client for 2 seconds.cod black ops 2 drone de chasse To start receiving the navigation data, you must issue the command.black ops 2 diesel drone This will start a log in logs/drone.log that will record thehow much does a police drone cost navigation data for you. media markt parrot ar drone

You can control what is printed out to the The Navigation Data is stored in a atom that is a map. The nav stream will keep going unless interrupted or called to end by Example Program to log navigation data for a flight You can configure the drone to detect pre-defined tags on the horizontal and vertical cameras. You first need to tell the drone which targets to detect on what cameras. msp430 parrot ar drone quadcopter controlHere is an exampleremote control drone gps Why shouldn't the AR drone have goals and beliefs? Inspired by John McCarthy's Ascribing Mental Qualities to Machines , the AR drone can execute behavior based on defined goals and beliefs and log its progress in the drone.log. The way it works is the function that continually processes the navigation input, looks at the

atom that holds the list of the current goals. processes these goals one at a time. That is it will not process the second goal in the list until the first goal completes. Belief-actions are defined using the def-belief-action macro. takes a readable str for the belief, a predicate function of the nav-data map to see if it "believes" the statement or not. it takes another function of the nav-data map to define what the action it should take is, if it holds the belief to be true. Goals are defined using the def-goal macro. It takes a readable str for the goal, a predicate function of the nav-data map to see if the goal has been reached. Finally it takes a vector of belief actions that it evaluates until the goal has been reached. The list of current goals is set via function set-current-goal-list. The current-goal-list is an atom, so the goals can be changed mid flight and immediately communicated to the navigation thread.

For a further example of navigation goal processing, see example/nav-goals The video can viewed as it goes - We convert the h264 video to pngHere is a sample: The raw video can be saved on a flight while you are viewing it. The resulting video file will be saved to vid.h264. the video into a playable form with ffmpeg. You need to have ffmpeg Converting video can be done with the following command. ffmpeg -f h264 -an -i vid.h264 stream.m4v Once the video is in png format, it can be sent to OpenCV forThere is an example of facial recognition in theOpenCV requires native java bindings to run. The native library for MacOS and opencv jar can be found in the opencvIf you have a different OS, you will need to download OpenCV and copy the native lib there. To control multiple drones, you need to first get them all on the same (Thanks to Jim Weirich for helping create the script and get this going.) Connect your computer to the first drone's network.

Create the following file as adhoc.sh. This shell script will temporarily change the network to an adhoc network named "multidrone_ah" and assign it a static ip of 192.168.1.100. The next time you reboot your drone, things will be back to normal. Connect your computer to the second drone's network. Now you are ready to run the program. There is an example multi-drone.clj in the examples directory. Multi-drone navigation data and multi-drone with beliefs and goalsSee examples/multi_drone_nav_goals.clj for an example. The tests use Midje. Copyright © 2013 Carin Meier Distributed under the Eclipse Public License, the same as Clojure.Flying drones had become increasingly popular not only among photographers but also among hobbyists who find a lot of thrill and challenge in flying an unmanned aircraft. Most of today's drones are quadcopters or drones with four propellers which people find more appealing because of their mechanical simplicity.

People should remember that flying a drone has its own set of rules. They can try to check if there's a locally organized drone flying club in their area where they can meet other flying enthusiasts and become more aware of the circumstances involved in flying. When choosing the best drone, there are only a few things to consider. These include battery life, camera, and of course the budget. Here are the best drones to buy in the market. DJI Phantom 2 Vision+ Quadcopter DJI drones are known to be packed with professional level features. This model is the latest drone from the company which features a built-in super high quality camera. It can shoot stills at 14MP and 1080p for video. Other camera features include Adobe's lens profile support, 3-axis camera stabilization and tilting capacity for easier aiming. Flight time has a maximum of 25 minutes. While the range is Wi-Fi limited, it can extend up to 700m with the help of one's smartphone. It also needs real joysticks for the control.

When it slips out of range, the drone can simply detect a signal break and will automatically start to fly back to its owner. Designed with professional grade filming and photography, the Turbo Ace Matrix is the daddy of drones. It features a wingspan of 1 meter, triple carbon fiber deck build, 8-inch monitor and 8,000mAh battery that allows it to stay in the air for 25 minutes. The range is measured at 1.2 miles. Each unit can carry gimbals and cameras on top for those who are keen on high definition filming and photography. It's also a "transformer drone" since it can be folded down for extra convenience during transport. While this type of drone has no built-in camera, it does have a gimbal for attaching a GoPro shutter. Its most impressive feature is the tilt controls. It can easily be manipulated through a mobile app. Users can steer the drone simply by tilting the mobile app in back and forth motion. At $158, this drone is one of the cheaper ones available in the market today.

Still, it offers a number of the same features found among its counterparts. Its most premium feature is the ability to transmit first-person-view (FPV) video. This means that the user can view it directly on the controller. Moreover, videos can be captured straight into an SD card. Parrot MiniDrone Rolling Spider This mini drone from Parrot sells for $99.99. It's a handheld compact drone that can fly up to a range of 20 meters with speeds reaching up to 11mph. It's great for both indoor and outdoor flying. The drone can be manipulated through the phone's Bluetooth 4.0 LE connectivity. It can also take pictures at a small resolution of 300,000 pixels. Nano QX RTF with SAFE This drone model is the perfect practice drone for new enthusiasts. It uses the Sensor Assisted Flight Envelope (SAFE) technology which can limit the drone controller's ability. The result is flying the tiny aircraft with the needed stability and agility. This quadcopter is ready to fly right out of the box and has been designed to carry a camera such as the popular GoPro.
