1 00:00:01,290 --> 00:00:07,620 In this lesson we will be starting to program our drones with Python before we get into programming. 2 00:00:07,620 --> 00:00:16,740 I want to check on the documents go to h TTP s Khan slash slash store dot DJI dot com. 3 00:00:16,740 --> 00:00:19,750 This will take you to the DJI store. 4 00:00:19,890 --> 00:00:26,310 Click on the tallow drone on the right side of the screen here you will see both tallow and Teller I 5 00:00:26,310 --> 00:00:34,560 do we will be programming so that both of the tallow products can run on it as the tallow is an older 6 00:00:34,560 --> 00:00:36,440 version with less functions. 7 00:00:36,510 --> 00:00:43,860 We will be looking into the tallow Adu to check on documents so click on the tallow and you scroll all 8 00:00:43,860 --> 00:00:50,540 the way down down down on the bottom of the page you will find this tiny link. 9 00:00:50,850 --> 00:00:54,480 Click on the link that says click here. 10 00:00:54,570 --> 00:00:59,380 Here you will find the documents for Tello Edu. 11 00:00:59,400 --> 00:01:05,250 There are multiple documents such as scratch read me where you can program your drone using Scratch. 12 00:01:06,360 --> 00:01:12,240 But in this lesson we will be looking at the SDK 2.0 User Guide. 13 00:01:12,240 --> 00:01:18,240 Click on the user guide you will see the user guide in a PD f format. 14 00:01:18,240 --> 00:01:24,900 We won't be going into the entire document during this lesson but just a quick look here you can see 15 00:01:24,900 --> 00:01:28,230 which IP addresses we will be using. 16 00:01:28,260 --> 00:01:34,010 Also the port number which is 8 8 8 9 to communicate and receive responses. 17 00:01:34,380 --> 00:01:41,530 Or if you want to receive the telco status the port number will be 8 8 9 0 for a video stream. 18 00:01:41,550 --> 00:01:45,830 The port will be 1 1 1 1. 19 00:01:45,860 --> 00:01:50,060 Now I want you to scroll down a bit to Tello commands. 20 00:01:50,060 --> 00:01:56,010 When you communicate between your Mac and your Tello you will be using UDP. 21 00:01:56,160 --> 00:01:58,080 Here you will see the actual commands. 22 00:01:58,080 --> 00:02:07,240 You will need takeoff means to command your drone to take off and land means to land which is quite 23 00:02:07,240 --> 00:02:08,970 straightforward. 24 00:02:08,980 --> 00:02:12,660 We need these commands to program how the drone should operate. 25 00:02:12,730 --> 00:02:19,090 If you want to fly the drone higher you need to set command up followed by a number which will be the 26 00:02:19,090 --> 00:02:22,750 height of how much you want the drone to fly higher. 27 00:02:22,750 --> 00:02:29,290 Go ahead and read through the command lists so you can have an idea of what kind of commands exist. 28 00:02:29,320 --> 00:02:35,380 Unfortunately we won't be going through every single command during this course but we will be using 29 00:02:35,380 --> 00:02:41,020 enough command so you will understand how the drone works with these commands and you will know how 30 00:02:41,020 --> 00:02:44,600 to use the commands on your own. 31 00:02:44,610 --> 00:02:47,520 Now let's go back to the Tello edu page. 32 00:02:47,520 --> 00:02:54,510 This time we'll click on the link where it says view sample codes once you click on the link the page 33 00:02:54,510 --> 00:03:03,650 will move to the Hub page here you will find sample codes for Python this video is made in March 20 34 00:03:03,650 --> 00:03:04,690 19. 35 00:03:04,730 --> 00:03:11,110 You can see that the codes have been updated 14 days ago depending on when you're checking this. 36 00:03:11,120 --> 00:03:14,510 You may be seeing a slightly different list. 37 00:03:14,570 --> 00:03:20,660 Let's check and see some of the sample codes on the top of the lists you'll see single Tello test. 38 00:03:20,660 --> 00:03:25,110 Click on the link and the list you'll find Tello dot P Y. 39 00:03:25,160 --> 00:03:26,420 Click on that as well. 40 00:03:27,600 --> 00:03:34,440 And the sample code you will see some codes using socket to connect the Tello and sending commands. 41 00:03:34,440 --> 00:03:39,690 If you check where the print command is written you will see that there is a space between the print 42 00:03:39,870 --> 00:03:41,700 and the text. 43 00:03:41,700 --> 00:03:45,870 This is a style used for Python to in our lesson. 44 00:03:45,870 --> 00:03:47,860 We won't be using a sample code. 45 00:03:48,000 --> 00:03:52,280 We will be creating our own codes from scratch. 46 00:03:52,290 --> 00:03:56,370 There is a reason we won't be using these standard codes. 47 00:03:56,370 --> 00:04:01,380 Now let's go back to Tello python and click on Tello video. 48 00:04:01,390 --> 00:04:07,640 This goes is for the purpose of streaming videos from the drone onto your computer. 49 00:04:07,660 --> 00:04:15,100 There are packages ready for you to install and I've tried all three packages for Linux Mac and Windows 50 00:04:15,700 --> 00:04:19,960 but unfortunately the Mac and Windows package didn't work. 51 00:04:19,960 --> 00:04:27,750 The Linux version did work a bit but with the newer version of Python it didn't correspond correctly. 52 00:04:27,900 --> 00:04:35,090 I didn't want to go through such a hassle so I create an original code using open c v and f of MPEG. 53 00:04:35,160 --> 00:04:40,380 This where we can easily install the tools we need in a more simple manner. 54 00:04:40,380 --> 00:04:43,460 I'm not saying everything on the site doesn't work. 55 00:04:43,560 --> 00:04:49,220 Maybe in the near future once it catches up with Python 3 we may be able to use it more. 56 00:04:49,350 --> 00:04:53,520 You might want to look into this site once in a while for the updates. 57 00:04:53,520 --> 00:04:58,710 The sample codes are great to look into so you can learn more things to do with your drone. 58 00:04:58,740 --> 00:05:03,030 In our next lesson we will be creating codes to actually fly the drones.
