Crazyflie Nano Quadcopter Kit 10-DOF with Crazyradio (BC-CFK-02-B) [ROB01315M] - $179.00

Raspberry Pi pre-configured SD-card image July 8th, 2013 Marcus 6 Responses In order for users to be able to pilot the Crazyflie from platforms without a graphical user interface there’s now a headless client in the repository named cfheadless. It’s intended to be run the command-line and is still under development, but working. The main reason it was made in the first place was to enable flying from the Raspberry Pi. To use the image you have to edit the configuration if needed and then just connect your controller, power on the Crazyflie and lastly connect the Crazyradio. The image can be downloaded using this torrent or via direct download. You can skip to the end and leave a response.

Video: Throwing and catching an inverted pendulum – with quadrocopters Two of the most challenging problems tackled with quadrocopters so far are balancing an inverted pendulum and juggling balls. My colleagues at ETH Zurich’s Flying Machine Arena have now combined the two. As part of his Master thesis Dario Brescianini, student at ETH Zurich’s Institute for Dynamic Systems and Control, has developed algorithms that allow quadrocopters to juggle an inverted pendulum. If you are not sure what that means (or how that is even possible), have a look at his video “Quadrocopter Pole Acrobatics”: (Don’t miss the shock absorber blowing up in smoke at 1:34!) The Math A quadrocopter with a plate for balancing the pole. To achieve this feat, Dario and his supervisors Markus Hehn and Raffaello D’Andrea started with a 2D mathematical model. This first step allowed to determine (theoretical) feasibility. Analyze, Experiment, Repeat The shock absorber at the end of the pendulum is a balloon filled with flour and attached to a sliding metal cap with zip ties. Dario writes:

projects:crazyflie:hacks:rasberrypi - Bitcraze Wiki In order to make it easy for users that have a Raspberry Pi to test out our headless client we prepared an SD-card image that is ready to use out of the box. The full SD-card image, and instructions on how to install it are located here. Instead of the official Python headless client, there is also a working Ruby version of the headless client, developed by a user. This version, called Crubyflie, can be installed on top of the SD-card image described above or on a standalone version of Linux/Debian/Raspbian. It allows you to adjust control variables (like X-mode or max thrust) by changing the values in a configuration file. For more information visit the Crubyflie installation page. As an alternative to a full SD-card image, you can manually install the headless Python client as a program on your Pi. For the following installation instructions it is assumed that you are running the popular Raspbian distrubution on your Pi. Setup the Crazyradio dongle Install the headless client #! #! Important

Autonomous quadrocopters fly in 20-strong formation The nanobot quadrocopters at the University of Pennsylvania's General Robotics, Automation, Sensing and Perception (Grasp) laboratory continue to go from strength to terrifying strength. We've seen the autonomous vehicles flip, roll and even zip through tight windows with impeccable grace. We've seen them sport a pincer-like claw for picking up a payload. If the object is too heavy, multiple machines can work together to offset the weight. The autonomous micro-helicopters are also adept architects, and can work together to construct complex towers. "We tell the quadrotors what structure to build and they figure out the assembly plan and then build it," said team member, Daniel Mellinger. In their latest performance, Grasp engineers show how massive groups of quadrocopters can work together in large formations. "We developed a method to transition between formations in 3D," a Grasp researcher says, as a perfectly aligned battalion of 20 drones suddenly spirals out into a large ring.

Трикоптер (Квадрокоптер своими руками: Часть II.2) Я конечно помню что обещал написать третью часть про полеты по GPS и прочие плюшки, но так случилось что всё лето провел с сыном, паяльником и Arduino IDE, а не в поле с коптером, поэтому сейчас мой вольный перевод статьи шведа Девида Виндэстоля (David Windestål, надеюсь правильно написал) о постройке трикоптера — пепелаца с тремя моторами и поворотным механизмом для компенсации вращения и управления поворотом. (большая просьба не ходить без особой надобности на сайт оригинала, так как он и без хабра часто падает, а так же под катом очень много картинок) С момента постройки трикоптера первой версии я всё пытался найти способы улучшения конструкции: постоянно менял пропеллеры, моторы, регуляторы скорости, длину лучей, поворотный механизм и т.д. Часто я менял кучу всего перед каждым полетом. В общем постоянно пытался найти оптимальный для себя вариант. Я обожаю стяжки. Они делают процесс постройки легким и быстрым. Основные детали Детали рамы Потребуется 10 штук M3x16 мм болтов.

[Guide] Decompile with Apk Tool [Easy Way] ## Due to exams I won't be able to reply on questions, there are however many experienced developers active on this thread like @SpaceCaker & @K.A. ## I have seen a lot of guides on how to decompile with Apk Tool, but none are noob friendly, so I thought I would post this. What You Need: ApkTool Java JDK/JRE 32 bit Super Basic Cmd/terminal knowledge (My 5 year old brother can handle this) Download Apk Tool Here: (Must be this one) 4Shared ( Slow and signup eeuww )Mega ( Ah much better ) First you need to extract that zip folder to anywhere you choose, preferably on root of c/drive E.g: C:/android/apktool extracting the files to 'apktool' folder. Now copy the apk you would like to mod into your Apk Tool folder. Command Prompt: Open up your Command Prompt by going to: Start -> run -> type : Cmd Code: Your cmd will probly look like this.. Installing Framework: Now that you are in directory we need to install the device's framework to your system for it to compile correctly so type this: Decompiling:

projects:crazyflie:userguide:index - Bitcraze Wiki What is the Crazyfile Nano Quadcopter used for It can be used for a number of things but the primary usage is as a development platform and for quadcopter enthusiasts that would like a nano-quad. Here's a list of some possible uses: Implementing and testing control algorithms Adding functionality using the expansion interface Creating applications on the host side that control the quadcopter Help us out with implementing new features and finding/fixing bugs to make it an even better platform What do you need for flying Here's a short list of what is needed for flying: A controller for input of flight commands (joystick). Basic concepts The Crazyflie is controlled from a computer using an input device such as a game controller (PS3 or Xbox 360). Flying The Crazyflie has 4 different controls: roll, pitch, yaw and thrust. Changing the yaw will make the quadcopter spin. The thrust is used to control the altitude of the quadcopter.
