00:00.110 --> 00:01.370
Hi robotic enthusiast.

00:01.580 --> 00:05.480
The purpose of this section is to build a real robot.

00:05.810 --> 00:11.810
All the functionalities and the concepts that we have applied only in simulation so far can finally

00:11.810 --> 00:14.780
be used to move and control a real robot.

00:14.870 --> 00:17.060
A real prototype with our voice.

00:17.710 --> 00:20.710
With this, you will have two tools at your disposal.

00:20.770 --> 00:26.650
A simulated robot and a real robot on which you can experiment and develop new features.

00:27.190 --> 00:34.240
This last section of the course is optional since we will be using real hardware, some mechanical and

00:34.240 --> 00:35.600
electronic components.

00:35.620 --> 00:40.810
It is not required for you to follow the implemented steps in the lessons.

00:40.810 --> 00:46.150
If you don't have the hardware or you don't think is the right time to purchase the needed components.

00:46.480 --> 00:52.690
You can choose to skip this section completely and come back in the future when you will have the required

00:52.690 --> 00:53.650
components.

00:53.680 --> 00:59.890
You can also decide to follow this section as an observer and take advantage of all the resources and

00:59.890 --> 01:05.860
lessons that are provided in this course, which might be helpful in the future to make your project

01:05.860 --> 01:07.750
your robot become reality.

01:08.700 --> 01:15.630
As I mentioned earlier in this section, we will use some hardware components, both mechanical and

01:15.630 --> 01:16.590
electronic.

01:16.980 --> 01:21.210
Among these, you will need an Arduino, Uno or any compatible board.

01:21.570 --> 01:28.080
This board is a microcontroller that we can program and is well suited for controlling hardware devices

01:28.080 --> 01:35.430
like sensors and actuators, thus acting as intermediary between Russia and the electronics and the

01:35.430 --> 01:36.300
actuators.

01:36.990 --> 01:43.230
And then to actuate the arm and the gripper we use for servo motors, one for each movable joint of

01:43.230 --> 01:44.070
the robot.

01:44.400 --> 01:49.860
You will also need some cables or jumpers to connect the servo motors to the Arduino.

01:50.510 --> 01:56.630
You also need an USB cable, which is normally provided with the Arduino to connect the board to the

01:56.630 --> 01:56.960
PC.

01:57.830 --> 02:03.980
This cable will supply the needed power to the board and allow us to program the board and interface

02:03.980 --> 02:04.940
it with Ros to.

02:05.860 --> 02:12.430
Next regarding the mechanical part, if you have access to a 3D printer, you can directly print all

02:12.430 --> 02:16.750
the robot's components using the CAD files attached to this lesson.

02:17.290 --> 02:19.300
Otherwise you can find.

02:21.160 --> 02:27.280
Otherwise you can find manipulator robots with a very similar architecture to the one that we used in

02:27.280 --> 02:30.370
the course from various online retailers.

02:30.400 --> 02:36.250
Many of these kits also very often include the servo motors and the electronics for the control.

02:36.760 --> 02:43.690
Finally, to assemble these components, you will also need an M3 type screws and bolts.

02:43.690 --> 02:47.650
And of course you will need a screwdriver to put everything together.

02:48.380 --> 02:55.340
In the upcoming lessons before assembling and programming the robot, we will develop some simple examples

02:55.340 --> 03:00.800
to interface Arduino with Ros to which you can use as a starting point for your future projects.
