WEBVTT 00:00.680 --> 00:01.910 Hi robotic enthusiast. 00:02.390 --> 00:06.590 The goal of this course is to create a real working robot. 00:06.860 --> 00:12.830 We will develop and use this manipulator robot to test the code and the concepts that we will cover 00:12.830 --> 00:18.770 during the course and that you can use them to play and experiment with new ideas during and after the 00:18.770 --> 00:19.370 course. 00:19.960 --> 00:24.900 If you don't have all the necessary hardware to build the actual robot anyway, don't worry. 00:24.910 --> 00:30.100 We will also have a simulated environment where you can experiment and develop the same functionalities 00:30.100 --> 00:33.520 and application using the simulated robot on your PC. 00:34.360 --> 00:40.240 While building the robot and writing the software as we add new abilities to it, I will explain the 00:40.240 --> 00:43.330 mathematics and the logic behind its functioning. 00:43.540 --> 00:50.410 I will also explain how Ros2 works, which is the second and newest version of Ros that stands for Robot 00:50.410 --> 00:56.470 Operating System, which is a framework that is commonly used by the most innovative robotics companies, 00:56.500 --> 00:58.960 universities, and even by NASA. 00:59.960 --> 01:05.420 Throughout the course, theoretical lessons will be followed by practical laboratory sessions where 01:05.420 --> 01:08.240 we will develop the code for our robot together. 01:08.510 --> 01:14.540 You will notice that these sessions are duplicated because we will develop the same code and the same 01:14.540 --> 01:20.990 functionalities both in C plus Plus and Python, which are among the most widely used programming languages 01:20.990 --> 01:22.040 for robotics. 01:22.430 --> 01:25.430 You are free to choose which laboratory lesson to follow. 01:25.460 --> 01:30.050 The one, for example, that uses the programming language you are most proficient with. 01:30.380 --> 01:34.430 Anyway, I will suggest you to follow both the laboratory lessons. 01:34.850 --> 01:40.730 This way you will take the most out of the course and you will boost your robotic software developer 01:40.730 --> 01:46.400 career, as there are many companies out there that are using both these programming languages for their 01:46.400 --> 01:47.120 robots. 01:48.170 --> 01:54.980 We will start by developing a simulation of our robot to test the new functionalities we will be implementing 01:54.980 --> 01:57.620 before installing them on the actual robot. 01:57.860 --> 02:04.610 The simulation will be useful not only if you decide not to build the real robot with the actual hardware, 02:04.610 --> 02:11.060 but also for testing your code faster, safer in the simulated environment before potentially damaging 02:11.060 --> 02:11.870 the robot. 02:12.770 --> 02:17.960 Next we will move on, controlling and moving the joints and the motors of our robot. 02:18.200 --> 02:24.110 We will discover how difficult it is to coordinate the movements of each motor, to grasp an object 02:24.110 --> 02:28.010 and understand the importance of mathematics for robotics. 02:28.900 --> 02:35.230 I will convince you to embarrass this study of few simple equations that will allow us to move the robot 02:35.230 --> 02:38.050 in a more intuitive and straightforward way. 02:39.020 --> 02:45.380 This way we will be able to create increasingly complex applications and more elaborate movements, 02:45.380 --> 02:51.110 ensuring that the robot executes them in a simple manner by automatically coordinating the movements 02:51.110 --> 02:52.220 of all the joints. 02:53.740 --> 02:59.890 Once the robot is capable of performing complex movements, we will move on, giving commands through 02:59.890 --> 03:03.610 our voice using the Amazon Alexa Voice Assistant. 03:03.910 --> 03:07.090 We will integrate it with our robot and with Ros to. 03:07.930 --> 03:11.500 Also in this case, you won't need to purchase anything unless you want to. 03:11.740 --> 03:18.370 I will show you a way to give voice comments to the robot simply using your PC and a web browser. 03:19.650 --> 03:25.590 After experimenting and developing new functionalities in the simulator, we will then proceed to build 03:25.590 --> 03:27.000 the real robot. 03:27.030 --> 03:33.390 We will learn to interact with the Arduino Rapid Prototyping board through Ros two and we will use the 03:33.390 --> 03:38.460 same software that we developed and tested in the simulation also for the real robot.
