Team meeting 

 In the meeting this week, the project leader Jason came up with two task. The first task, was to go and explore the ubidots IOT platform using a tutorial on images and videos. The second task, was to explore ardupilot (which is an opensource, unmanned vehicle autopilot software suite, capable of controlling autonomous: Multirotor drones). After this two task were put on the table, he gave each of us to choose which one we wanted to do. I went with exploring ubidots and my team members were jack Pender, Erinn and Kevin Power.

Meaning

Ubidots is an Internet Of Things (IOT) application builder with data analytics and visualization.

Pros

  • Digital and Analog I/O
  • Visual display (Camera feedback)
  • Informative dashboard
  • Gps features (Maps)
Tutorial
It contains a python file that counts the number of people in an image. It also interacts with various  digital I/O ubidots widgets.

Equipment used
Raspberry Pi was used as my equipment for this tutorial 

Steps taken
Installed Python3 and opencv (the necessary packages needed to run the python file)
Downloaded the python file 
Downloaded several images as testcases
Ran the python file against one of the testcases using Python3 
Checked the testcase to see if the code worked which it did

Issue encountered
Wasnt able to display the images up to ubidots on the html canvas widget and this led to me not being to run the python file against the imgaes in  ubidots.

Next step 
  • Trying to get the issue encountered above fixed
  • Displaying the live camera feed from the tello drone up to ubidots using the html canvas widget

How to: Tello drone to micro bit - Victor Alikberov, Blog#1

Image
1. Introduction. The purpose of this blog is to explain everything that is needed in order to connect tello drone to micro bit. It will cover wiring,  javascript code behind custom created tello extension and how to use this extension to connect and drive tello via microbit. 2. Wiring. Since tello drone creates its own wi-fi hotspot, additional wi-fi module is required in order to establish wireless connection between micro bit and tello. ESP8266 will be used to connect micro bit to tello wi-fi hotspot and also to establsih UDP communications between micro bit and drone. The pinout of the ESP8266 chip is shown below. ESP8266 chip pinout. Receiving port (Rx) is connected to transmitting port of the micro bit (pin 2) and transmitting port (Tx) of the ESP8266 is connected to receiving port of the micro bit (pin 1).  3.3 volts power supply should be provided both to micro bit and ESP8266 chip. Chip enable port is also connected to 3.3v power supply.  ESP8266 plus microbi...

Colour Tracking With OpenCV - Jack Pender, Blog #4

Image
  Introduction: As part of this project, the Tello drone is intended to locate anyone in danger in the water and transmit this location for the USV to travel to so it can perform a rescue. Having accessed the camera feed from the Tello and displaying it where it can be monitored, the next step was to have it implement some form of tracking. For test purposes it was decided to detect the colour green. OpenCV: The colour tracking was to be implemented in OpenCV and so I simply had to edit the python file that was running the livestream. The first step of this was to import the numpy library as this would be used to calculate the area of the detected green object. This library would also allow me to set the range of colours that the Tello was to detect. It does so by creating an array of RBG values ([22,60,200] and [60,255,255] in my case) that OpenCV can use to detect these specific colours and everything that falls in between. Here I am using these values as the brightest and ...

Tello and OpenCV - Jack Pender, Blog #3

Image
  Introduction: One of the main aspects of this project is to use a drone to locate people who are in danger in the water, then transmitting this location to the USV so that it can make its way there. The first step of this was to get the camera feed from the Tello drone and stream this to a computer, in this case, mine. In order to do this my first task was to research the topic online and see if there was anything I could use. Luckily, there was. First Steps: There happened to be a few tutorials online, from articles to YouTube videos, that were able to help me get started. The first step in this process is connecting to the Wi-Fi network of the Tello drone, in order to stream its camera feed via OpenCV. This is a public Wi-Fi network, so it’s very quick and easy to connect to. Then came the python programming using OpenCV in order to actually get the camera feed from the drone. The tutorials that I found allowed this setup to be very easy. Firstly, you set up the parameter...
