In this blog, we will be learning how to program some basic movements in a drone with the help of Python. The drone we will use is Dji Tello. We will learn drone programming with Scratch, Swift, and even Python.  

 A step-by-step guide to learning drone programming

We will go step by step through how to issue commands through the Wi-Fi network 

drone programming
Drone – Data Science Dojo

 

Installing Python libraries 

First, we will need some Python libraries installed onto our laptop. Let’s install them with the following two commands: 

 

pip install djitellopy 

pip install opencv-python 

 

The djitellopy is a python library making use of the official Tello sdk. The second command is to install opencv which will help us to look through the camera of the drone. Some other libraries this program will make use of are ‘keyboard’ and ‘time’. After installation, we import them into our project   

 

import keyboard as kp 

from djitellopy import tello 

import time 

import cv2 

 

 Read more about Machine Learning using Python in cloud

Connection

We must first instantiate the Tello class so we can use it afterward. For the following commands to work, we must switch the drone to On and find and connect to the Wi-Fi network generated by it on our laptop. The tel.connect() command lets us connect the drone to our program. After the connection of the drone to our laptop is successful, the following commands can be executed. 

 

tel = tello.Tello() 
tel.connect() 

 

 

Sending ending commands to the drone 

We will build a function which will send movement commands to the drone.  

def getKeyboardInput(img): 

    kp.init() 

    lr, fb, ud, yv = 0, 0, 0, 0 

    speed = 50 

    if kp.getKey("LEFT"): 

        lr = -speed 

    elif kp.getKey("RIGHT"): 

        lr = speed 

 

    if kp.getKey("UP"): 

        fb = speed 

    elif kp.getKey("DOWN"): 

        fb = -speed 

 

    if kp.getKey("w"): 

        ud = speed 

    elif kp.getKey("s"): 

        ud = -speed 

     

    if kp.getKey("a"): 

        yv = speed 

    elif kp.getKey("d"): 

        yv = -speed 

 

    if kp.getKey("l"): 

        tel.land() 

    if kp.getKey("t"): 

        tel.takeoff() 

 

    if kp.getKey("z"): 

        cv2.imwrite("Resources/images/{time.time}.jpg", img) 

        time.sleep(0.05) 

    return [lr, fb, ud, yv] 

tel.streamon() 

 

 

The drone takes 4 inputs to move so we first take four values and assign a 0 to them. The speed must be set to an initial value for the drone to take off. Now we map the keyboard keys to our desired values and assign those values to the four variables. For example, if the keyboard key is “LEFT” then assign the speed with a value of -50. If the “RIGHT” key is pressed, then assign a value of 50 to the speed variable, and so on. The code block below explains how to map the keyboard keys to the variables: 

if kp.getKey("LEFT"): 

        lr = -speed 

    elif kp.getKey("RIGHT"): 

        lr = speed 

 

 

This program also takes two extra keys for landing and taking off (l and t). A keyboard key “z” is also assigned if we want to take a picture from the drone. As the drone’s video will be on, whenever we click on “z” key, opencv will save the image in a folder specified by us. After providing all the combinations, we must return the values in a 1D array. Also, don’t forget to run tel.streamon() to turn on the video streaming.     

We must make the drone take commands until and unless we press the “l” key for landing. So, we have a while True loop in the following code segment: 

 

Calling the function

 

while True: 

    img = tel.get_frame_read().frame 

    img = cv2.resize(img,(360,360)) 

    cv2.imshow('Picture',img) 

    cv2.waitKey(1) 
 
    vals = getKeyboardInput(img) 

    tel.send_rc_control(vals[0],vals[1],vals[2],vals[3]) 

    time.sleep(0.05) 

 

 

 

The get_frame_read() function reads the video frame by frame (just like an image) so we can resize it and show it on the laptop screen. The process will be so fast that it will completely look like a video being displayed.  

The last thing we must do is to call the function we created above. Remember, we have a list being returned from it. Each value of the list must be sent as a separate index value to the send_rc_control method of the tel object 

 

Execution 

 

Before running the code, confirm that the laptop is connected to the drone via Wi-Fi. 

Now, execute the python file and then press “t” for the drone to take off. From there, you can press the keyboard keys for it to move in your desired direction. When you want the drone to take pictures, press “z” and when you want it to land, press “l” 

 

Conclusion

 

In this blog, we learned how to issue basic keyboard commands for the drone to move. Furthermore, we can also add more keys for inbuilt Tello functions like “flip” and “move away”. Videos can be captured from the drone and stored locally on our laptop

R programming knowledge is vital for scientists, as evidenced by R’s rapid rise in popularity.

Not surprisingly, we teach the R language used in programming in our Bootcamp. However, per our mission of “data science for everyone,” most of our students do not have extensive programming backgrounds.

Even with our students that code, R language skills are quite rare. Fortunately, our students universally share skills in using Microsoft Excel for various analytical scenarios. It is my belief that Excel skills are an excellent foundation for learning R. Some examples of this include:

  • The core concept of working with data in Excel is the use of tables – this is exactly the same in R.
  • Another core Excel concept is the application of functions to subsets of data in a table – again, this is exactly the same in R.

I have a hypothesis that our experiences teaching Data Science around the world are indicative of the market at large. That is, there are many, many Business Analysts, Data Analysts, Product Managers, etc. looking to expand their analytical skills beyond Excel, but do not have extensive programming backgrounds.

Aspiring data scientist? You need to learn to code!

Understanding the programming language, R, is a vital skill for the aspiring Data Scientist as evidenced by R’s rapid rise in popularity. While the R language ranks behind languages like Java and Python, it has overtaken languages like C#. This is remarkable as R is not a general-purpose programming language. This is a testament to the power and utility of R language for Data Science.

Not surprisingly, when I mentor folks that are interested into moving into data science one of the first things I determine is their level of coding experience. Invariably, my advice falls along one of two paths:

  1. If the aspiring Data Scientist already knows Python, I advise sticking with Python.
  2. Otherwise, I advise the aspiring Data Scientist to learn R.

To be transparent, I use both R and Python in my work. However, I will freely admit to having a preference for R. In general, I have found the learning curve easier because R was designed from the ground up by statisticians to work with data. Again, R’s rapid rise in popularity as a dedicated language for data is evidence that others feel similarly.
