-# Working with GPIO
-
-A GPIO (General-Purpose Input/Output) pin is a programmable digital signal pin on a circuit board or a microcontroller that may act as an input or an output. Raspberry Pi has a set of easily accessible GPIO pins, some of which have hardware <abbr title="Pulse-width modulation">PWM</abbr>.
-
-> **Info** Use the [pinout](https://pinout.xyz) for figuring out, which Raspberry Pi's pins support GPIO and PWM.
-
-The [`pigpio`](http://abyz.me.uk/rpi/pigpio) library for interfacing with the GPIO pins is already preinstalled on [the RPi image](microsd_images.md). To interact with this library, run the appropriate daemon:
-
-```bash
-sudo systemctl start pigpiod.service
-```
-
-To enable automatic launch of the daemon, run:
-
-```bash
-sudo systemctl enable pigpiod.service
-```
-
-Example of working with the library:
-
-```python
-import time
-import pigpio
-
-# initializing connection to pigpiod
-pi = pigpio.pi()
-
-# set pin 11 mode for output
-pi.set_mode(11, pigpio.OUTPUT)
-
-# set signal of pin 11 to high
-pi.write(11, 1)
-
-time.sleep(2)
-
-# set signal on pin 11 to low
-pi.write(11, 0)
-
-# ...
-
-# setting pin 12 mode for input
-pi.set_mode(12, pigpio.INPUT)
-
-# read the state of pin 12
-level = pi.read(12)
-```
-
-To find out the pins' numbers, consult the [Raspberry Pi pinout](https://pinout.xyz).
-
-## Connecting servos
-
-Servo motors are typically controlled with PWM signal. Extreme positions of servos are reached with signal widths approximately equal to 1000 and 2000 µs. Values for a specific servo can be determined experimentally.
-
-Connect the signal wire of the servo to one of GPIO-pins of the Raspberry. To control a servo connected to the pin 13 use a code like this:
-
-```python
-import time
-import pigpio
-
-pi = pigpio.pi()
-
-# set mode of pin 13 to output
-pi.set_mode(13, pigpio.OUTPUT)
-
-# set pin 13 to output PWM signal 1000 us
-pi.set_servo_pulsewidth(13, 1000)
-
-time.sleep(2)

-To connect an electromagnet use a field-effect transistor (MOSFET). Connect the MOSFET to one of GPIO-pins of the Raspberry Pi. To control the magnet connected to the pin 15 use a code like this:
-
-```python
-import time
-import pigpio
-
-pi = pigpio.pi()
-
-# set mode of pin 15 for output
-pi.set_mode(15, pigpio.OUTPUT)
-
-# enable the magnet
-pi.write(15, 1)
-
-time.sleep(2)
-
-# disable the magnet
-pi.write(15, 0)
-```

-# Hostname
-
-[By default](microsd_images.md) the hostname of the Clever drone is set to `clever-xxxx`, where `xxxx` are random numbers. These numbers are the same as in the [Wi-Fi SSID](wifi.md).
-
-Thus, Clever is accessible on machines that support mDNS as `clever-xxxx.local`. You can use this name to access Clever over SSH:
-
-```bash
-ssh pi@clever-xxxx.local
-```
-
-Also, this name can be used in place of IP-address to open Clever web pages in browser, accessing ROS master, etc.
-
-## Changing hostname
-
-In some situations it is necessary to change Clever's hostname. You can use the `hostnamectl` utility for that:
-
-```bash
-sudo hostnamectl set-hostname newname
-```
-
-Where `newname` is the new name of the machine. `hostnamectl` utility will change the name in `/etc/hostname` file.
-
-You should also put the new name to `/etc/hosts` file:
-
-```txt
-127.0.1.1	newname newname.local
-```
-
-Setting `newname.local` is necessary to allow ROS to resolve this name in situations where all the network interfaces are down (when Wi-Fi is turned off or disconnected).
-
-> **Note** Changing the hostname does not affect the Wi-Fi SSID (and vice versa, changing the Wi-Fi SSID won't affect the hostname).

-# Human Pose Estimation drone control
-
-## Introduction
-
-Human pose estimation is one of the computer vision applications in order to estimate all the joints and the different poses of the human body through a special camera and a special hardware or process the images from a regular camera by machine learning and deep learning techniques. This project is about controlling the drone through the poses of a person in front of regular camera without needing to an external hardware or hard build dependencies on your computer.
-
-## Demo

-
-In the demo video, we were using Ubuntu 18.04 and clever4 drone.
-
-## Development
-
-We used posenet from tensorflow.js as our human pose estimation module because it is easier to use, build, fast and compatible with different environments(Hardware and OS). You can find the work of posenet for this project [here](https://github.com/hany606/tfjs-posenet). Websockets were used as communication protocol between the browser and a running server on the drone.
-
-## Architecture
-
-The image below is a visualization of our architecture for the project.
-
-![Architecture](../assets/human_pose_estimation_project_architecture.png)
-
-This figure is made from [here](https://www.draw.io/)
-
-## Dependencies
-
-Before you test it you need to install on your laptop:
-
-- Install Nodejs from [here](https://nodejs.org/en/download/). For [Ubuntu installation](https://tecadmin.net/install-latest-nodejs-npm-on-ubuntu/)
-- Install Yarn package manager from [here](https://yarnpkg.com/lang/en/docs/install/). [Usual problem](https://github.com/yarnpkg/yarn/issues/3189) while installing and using yarn with Ubuntu.
-- Have an experience in manual control on the drone in case of any weird behavior happen.
-- Worked before with COEX drones, if this is your first time to work with COEX drones check [this](https://clever.copterexpress.com/en/).
-
-and you are ready to build and use the required codes.
-
-## Setup & installation
-
-### In your main laptop
-
-#### (It has been tested until now only on Ubuntu 18.04)
-
-- Clone the repo of posenet in your computer or download it if you are using Windows without GitHub
-
-```sh
-git clone https://github.com/hany606/tfjs-posenet.git
-```
-
-- Do the steps of running and setup as it is described in the README [here](https://github.com/hany606/tfjs-posenet/tree/master/posenet)
-
-### In the Raspberry Pi of the drone (Main controller)
-
-- Access the Raspberry Pi
-- [Switch to Client mode](https://clever.copterexpress.com/en/network.html) and ensure that the network has internet connection.
-
-Notice: I have already made a bash script based on that tutorial, it is in COEX-Internship19/helpers/ called .to_client.bash
-To run it:
-
-```sh
-chmod +x .to_client.bash
-./.to_client <NAME_OF_NETWORK> <PASSWORD>
-```
-
-- Install the tornado library to make a WebSocket server
-
-```sh
-sudo pip install tornado
-```
-
-- Clone the main repo on the Raspberry Pi of the drone
-
-```sh
-git clone https://github.com/hany606/COEX-Internship19.git
-```
-
-- Go to the project directory
-
-```sh
-cd COEX-Internship19/projects/Human_pose_estimation_drone_control/
-```
-
-- Run the server to test that everything is correct and run the posenet, you should see a lot of data is printed in the terminal (if you are running the human pose estimation code on your main computer, just refresh the page in the browser after running the below command in Raspberry Pi)
-
-```sh
-python websocket_server_test.py
-```
-
-- Close the server using Ctrl+C
-- To run the main file
-
-```sh
-python main_drone.py
-```
-
-## How to use it
-
-- Run the server first from the Raspberry Pi from the correct directory
-
-```sh
-python main_drone.py
-```
-
-- Run Human pose estimation module on your laptop with WebSocket by
-
-```sh
-yarn websocket
-```
-
-Or refresh the page if you already run it.
-
-- You should see the instructions on the screen of the terminal of the Raspberry Pi right now.
-- Firstly, you should be visible for the camera and it is better to have a clear background without many details.
-- Secondly, you should do initial pose as it is described in the images below.
-- You can perform any pose and try to keep it until your drone finish doing this move that is corresponding to the pose.
-- After you do the pose return to the initial pose in order to give the drone the command to listen to another pose.
-- If you want to stop the program, land the drone and don't return to the initial pose and press Ctrl+C to stop the drone.
-
-## Poses
-
-![Poses](../assets/human_pose_estimation_project_poses.jpg)
-
-Animation is created by [this](https://justsketchme.web.app/)
-
-## Notes
-
-- Websockets are used to communicate between the page on the browser that runs posenet and the drone.
-- As the model of posenet is already pre-trained and using tensorflow.js. So, it is quite fast and can run on different computers without any problems thanks to yarn, parcel and tensorflow.js, and we have configured the code of posenet to the minimal configuration to not require a lot of computation power.
-- This project has been built in 1 week of working, it took a lot of time trying to make openpose and google colab working but unfortunately I had many errors and one I decided to move to posenet everything was pretty easy.
-- If you have any comments about the codes to try to improve it, I will be happy if you can contact me through telegram: @hany606 or email: h.hamed.elanwar@gmail.com or do pull requests.
-- If you have implemented any of the applications below, or do some improvements, we will be very happy for that.
-
-## Future application
-
-- [Drone wars](https://web.facebook.com/COEXDrones/photos/pcb.1129309377266616/1129308437266710/?type=3&theater): Control the drone during the drones battle using human poses. It requires high speed interaction and more precise control.
-- Control a drone that draw graffiti using human poses and draw in real-time.
-- Playing with balls like ping pong game with the drones. It may require 3D Human Pose estimation Algorithms.
-- Control two drones by your arms and do some task together.
-
-## Acknowledgments
-
-- This project was part of an internship in COEX in July 2019. if you found any bugs or problems, you can contact me through telegram: @hany606 or email: h.hamed.elanwar@gmail.com.
-- The above applications were thought by me and my internship supervisor Timofey.

-# Аэротакси
-
-Проект команды Human Express на проектной программе "Большие Вызовы"
-
-## Суть проекта
-
-Крупные города страдают из-за пробок и перегруженности транспорта. Пробки на дорогах и перегруженность транспорта влечёт за собой многие неудобства. Одной из таких проблем является отсутствие возможности быстро добраться из точки А в точку Б. При этом воздушное пространство практически не используется. Предлагаемое решение заключается в создании системы, которая в режиме реального времени наблюдает и контролирует движение беспилотных летательных аппаратов. Такое решение приводит к полной автоматизации процесса полёта и исключает возможность воздушно-транспортных происшествий. В результате проделанной работы удалось сделать систему, которая состоит из нескольких дронов и сервера. Сервер прокладывает маршрут дронам из начальной точки в заданную по проложенным дорогам. Также в работу сервера входит логистика, благодаря которой беспилотники не сталкиваются в полёте.

-
-## Настройка сервера
-
-Чтобы скачать проект на сервер выполните команду
-
-```bash
-git clone https://github.com/Tennessium/HUEX
-```
-
-Перед началом работы с системой необходимо подключить устройство к сети WiFi (например, раздать со смартфона) установить на него необходимые библиотеки
-
-```bash
-cd HUEX/server
-pip install -r requirements.txt
-```
-
-В случае необходимости вы можете изменить высоту эшелонов и разрешенные IP-адреса для доступа к Центру управления полетами в файле *server/consts.py* и настроить поле с метками в *server/static/map.txt*.
-Теперь можно запустить сервер написав в командную строку
-
-```bash
-python manage.py runserver 0.0.0.0:8000
-```
-
-Чтобы перейти на веб страницу наберите в адресной строке ip адрес сервера в локальной сети и укажите порт 8000 (`http://ip:8000`).  
-[Как узнать ip адрес устройства](https://remontka.pro/ip-adres/)
-
-## Настройка коптеров
-
-В первую очередь подготовьте SD-карту с образом Clever ([Инструкция](https://clever.copterexpress.com/ru/microsd_images.html))
-
-Чтобы скачать проект на Raspberry Pi в коптере выполните команду
-
-```bash
-git clone https://github.com/Tennessium/HUEX
-```
-
-Перед началом работы с системой необходимо перевести коптеры в режим клиента и подключить к сети WiFi. Вы можете воспользоваться [этим мануалом](https://clever.copterexpress.com/ru/network.html#переключение-адаптера-в-режим-клиента)
-
-Однако, для упрощения развертывания системы на нескольких коптреах, рекомендуется использование нашего скрипта, лежащего в папке *copter/setup/*
-
-- Перейдите в папку
-
-```bash
-cd HUEX/copter/setup/
-```
-
-- Используя любой редактор, в файле *networkData.txt* измените SSID и пароль сети
-- Запустите скрипт
-
-```bash
-sudo bash networkEdit.sh
-```
-
-- Перезагрузите Raspberry Pi
-
-Произведите установку и настройку ROS-пакета для LED-ленты
-
-```bash
-cd ~/catkin_ws/src
-git clone https://github.com/bart02/ros-led-lib.git led
-cd led
-```
-
-Воспользовавшись nano ledsub.py, измените переменную LED_COUNT на число светодиодов на вашей ленте
-
-```bash
-chmod +x ledsub.py
-cd ~/catkin_ws
-catkin_make
-sudo systemctl enable /home/pi/catkin_ws/src/led/led.service
-sudo systemctl start led
-```
-
-Установите необходимые пакеты
-
-```bash
-cd HUEX/clever
-pip install -r requirements.txt
-```
-
-В файле *copter/consts.py* укажите IP-адрес сервера.
-
-Для запуска основного скрипта воспользуйтсь нашим systemd-сервисом.
-
-```bash
-sudo systemctl enable /home/pi/HUEX/clever/setup/taxi.service
-sudo systemctl start taxi.service
-```
-
-Скрипт будет запускаться автоматически при старте системы.
-Для остановки можно воспользоваться командой
-
-```bash
-sudo systemctl stop taxi.service
-```
-
-## Веб-интерфейс центра управления полётами
-
-<img src="../assets/cup.png" alt=""/>
-В данном веб интерфейсе можно следить за полётами всех дронов на карте (масштабировать с помощью колёсика, передвигаять с помощью Alt). При нажатии на лебедя в правом верхнем углу все коптеры аварийно садятся, А при нажатии на значок "обновить" все коптеры автоматически удаляются, что приводит к удалению всех комманд и посадке активных на текущий момент коптеров.
-С помощью инструментов в правом нижнем углу можно строить новые основания и рёбра.
-
-## Веб-интерфейс заказа
-
-Чтобы перейти на веб страницу наберите в адресной строке `http://ip:8000/m`, где *ip* - адрес сервера в сети.
-
-## Визуализатор
-
-Для наглядности работы системы был разработан 3D-визуализатор воздушного пространства. Он отображает систему эшелонов, поле ArUco-маркеров; позиции коптеров и направления их движения в real-time.
-
-Запускать визуализатор можно после старта сервера. Компьютер должен быть подключен к той же сети, что и сервер.
-
-```bash
-cd viz
-python main.py
-```
-
-Программа автоматически подгрузит карты маркеров и эшелонов. Если одна из них изменяется в процессе эксплуатации, перезагрузите программу для внесения изменений.
-
-<img src="../assets/viz.png" alt=""/>
-
->Камеру можно передвигать при помощи клавиш *WASD* и поворачивать при помощи стрелок.
-
-## DDoS-скрипт
-
-Во время смены был написан простой скрипт, предназначенный для тестирования логистики. Его суть заключается в бесконечном заказе такси между случайными точками. Перед тем как запустить программу [*DDos.py*](https://github.com/Tennessium/HUEX/blob/master/DDos.py) замените параметр *static_path* в пятой строке на *ip* вашего сервера.
-
-## API
-
-На случай если вы захотите реализовать свою "обёртку" вы можете реализовать взаимодействие с сервером по средствам *HTTP/HTTPS* запросов
-
-### /get
-
-Возвращает телеметрию всех доступных коптеров.
-Пример:

-# Имя хоста
-
-[По умолчанию](microsd_images.md) на Клевере установлено имя хоста (hostname) `clever-xxxx`, где `xxxx` – случайные цифры. Имя хоста соответствует SSID [точки доступа Wi-Fi](wifi.md).
-
-Таким образом, Клевер доступен на машинах, поддерживающих mDNS, под именем `clever-xxxx.local`. Вы можете использовать это имя для SSH-доступа на Клевер:

-В некоторых ситуациях необходимо изменение имени хоста Клевера. Для это используйте утилиту `hostnamectl`:
-
-```bash
-sudo hostnamectl set-hostname newname

-
-Где `newname` – новое имя машины. Утилита `hostnamectl` поменяет имя в файле `/etc/hostname`.
-
-Также необходимо прописывание нового имени в файл `/etc/hosts`:
-
-```txt
-127.0.1.1	newname newname.local
-```
-
-Прописывание `newname.local` необходимо, чтобы ROS смог разрешить это имя в ситуациях, когда все сетевые интерфейсы неактивны (отключение/разрыв связи Wi-Fi).

-# Робокросс-2019
-
-В июле 2019 команда Коптер Экспресс в 4-й раз подряд одержала победу на ежегодных испытаниях беспилотных транспортных средств "[Робокросс](http://russianrobotics.ru/activities/robokross-2019/)". Испытания проводятся на полигоне ГАЗ под Нижним Новгородом.
-
-Основной задачей испытаний в категории БПЛА было локализовать и уничтожить цель — красный воздушный шар — в автономном режиме.

-
-## Реализация
-
-Команда использовала квадрокоптер на базе рамы F450 и [платформу Клевер](https://github.com/CopterExpress/clever). Полный итоговый исходный код доступен для изучения [на GitHub](https://github.com/CopterExpress/robocross2019/).
-
-Разработанный пакет `robocross2019` разбит на модули: ROS-нодлет `red_dead_detection` распознает красный шар, `balloon.py` реализует высокоуровневую логику полета коптера.
-
-## red_dead_detection
-
-Нодлет `red_dead_detection` обеспечивает обнаружение красного шара на изображении с камеры квадрокоптера, смотрящей вперед (топики `/front_camera/image_raw` и `/front_camera/camera_info`). Используется простейший метод фильтрации изображения по цвету. Затем вычисляется геометрический центр полученных участков и производится компенсация искажений камеры (`cv::undistortPoints`).
-
-Используя известное фокусное расстояние камеры (из топика `camera_info`) вычисляется вектор, направленный в сторону цели. Полученный вектор публикуется в топик `/red_dead_detection/direction`, причем его система координат (`frame_id` связана с расположением передней камеры `front_camera_optical`).
-
-## balloon.py
-
-Для полета к шару используется вектор направления `red_dead_detection/direction`, который используется как setpoint по скорости дрона. Угол по рысканью также устанавливается по направлению к шару. Цель считается уничтоженной, когда на протяжении заданного количества кадров общая площадь участка с красными пикселями меньше определенного порога.
