 This week I was asked by team leader Jason to get object color tracking working in roborealm using the green ball.

the RGB filter application

Steps taken

  • Clicked on the colour green to filter only the green colours
  • Left the remaining default settings
  • Clicked ok to exit
  • Placed the green ball in front of the webcam 


The Center Of Gravity application

Steps taken 

  • Set the stop tracking pixel area and density to below 0.02% and 10% in the filter section
  • Set the show bounding box area to around 80% of the pixel
  • Left the remaining default 
  • Clicked ok to exit
  • Placed the green ball in front of the webcam then the bounding box and the x and y coordinates of the ball was displayed

Mean filter

Steps taken

  • Set the mean filter size of the green ball to 12 so that the ball can be seen from afar and not pieces of the ball
  • Clicked ok
  • Placed the green ball in front of the webcam saw it was blurry which is one of the effects of setting the mean filter size
  • Placed the green far away from the webcam and could still see the whole green ball and not pieces of the ball

The object tracking application

Steps taken

  • Clicked on the object tracking application 
  • Left all default settings
  • Clicked ok
  • Placed the green ball in front of the webcam
  • Clicked on the green ball to activate the object tracking application. The application show a green box around the ball with increasing or decreasing percentages values as the ball is moved around.


Serial communication

Jason the project leader asked me to setup serial communication between roborealm and the microbit. so as the ball is moved to the left a value of one is sent to the microbit and as the ball is moved to the right a value of two is sent to the microbit.

Steps taken

  • Setup the serial communication application in roborealm
  • Setup the serial communication on the microbit


Setup the serial communication application in roborealm

Steps taken

  • Opened the serial communication application on roborealm by searching the name serial communication on the search bar on the left hand side of the roborealm application and double clicking on it.
  • Set the baud rate to 115200
  • Left the remaining setting as default
  • Clicked ok 


Setup the serial communication on the microbit

Steps taken

  • Searched up the how to setup serial communication on the microbit 
  • Tried using the serial communication extension by using the example given but came to conclusion this was a no go because the example given was for setting the x the y positions of the LED lights on the microbit
  • Went on to an alternative way whic is setting up serial communication using a terminal. 
  • Downloaded my first choice terminal which was cmder. After installation, the terminal was ran and there wasnt a serial port option and i made the decision that it was a no go.
  • Downloaded my second terminal which was Tera Term. After installation, the terminal was ran and the  serial option was seen by clicking the setup dropdown on the terminal window.
  • Clicked on the serial port option
  • Set the port speed to 115200 (the same as set in the robo serial communication application) 
  • Left the remaining the setting as default
  • Clicked ok to exit
  • Went back serial communication application on roborealm to set the port to the port that the microbit is listening on which is COM3. Once this was set, the port was discovered and the dialog box underneath kept repeating connection could not be established.

Next steps

  • Establishing a serial connection between roborealm and the microbit
  • Sending values to the microbit based on the position of the green ball in the roborealm application

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...

First USV Test - Jack Pender, Blog #5

Image
Introduction: On the 18 th of March we held our first field test at Killurin Bridge in Wexford. We met there at 10 am, with a plan of finishing up at 2 pm, giving us plenty of time to test each aspect of the project we have been working on. It was great to see the USV on the water for the first time, and it helped to visualise it in the setting that its use is intended for. Testing: The main tests for this first field test were to trial the driving functionality; Manual Drive, Microbit Drive and Cloud Drive. Using the controller, the drive of the USV was successful and it was great to finally see its speed and mobility on the water. With the Manual Drive, controlled by Patryck, going according to plan, this allowed us to test the Microbit Drive, which would be controlled by Adam. Using two Microbits to control the direction and thruster power, Adam completed a successful drive of the USV. This was great to see as it meant that the control of the USV could be friendly to everyone...

OpenCV To RoboRealm - Jack Pender, Blog #7

Image
Introduction: Developing further on getting the camera feed from the Tello drone to a viewable format, it was decided to try and get the camera feed into RoboRealm. Once the camera feed is in RoboRealm, it can essentially be sent to anywhere from there, in our case Ubidots, but if this were to change we would now have a better starting point. RoboRealm: RoboRealm was created in 2006 to take advantage of lower cost generic computing, a widening range of lower cost imaging devices, an increasing need and usage of vision as a primary sensor device and the desire to come to a solution with an interactive user interface with minimal programming. This made it ideal for this project as it meant that for future iterations it would be quick and simple for someone else to get up and running with. Procedure: Using multiple of the built-in features of RoboRealm I created a programe that would start a screen capture in order to have RoboRealm capture the drone feed. Firstly, within an if ...
