Nowadays, coronavirus or covid-19 is the greatest threat for all human beings. Staying at a safe distance and keeping a social distance is now the only way to stay safe. But, could we stay away if our family or a family member becomes infected? Obviously No... But unfortunately, we have to stay away...

To solve this problem, here I have made a Robot, which is controlled by a smartphone through wi-fi. This robot is capable of making a video call if you want to see the patient or vise-versa. This is also capable to carry necessary things. If you want to send something to the patient, it will carry and deliver it.

Step 1: Components

a very few components will be needed to make it. while making it, my first aim was to make it at the lowest price. So, I have used a wested PVC pipe to make the robot body. I have also used very common electronics components which are really very common and available at a very low price.

Step 2: Connection Diagram

Step 3: Arduino Code

Please follow the steps below, If you are new and not well familiar with this ESP8266 module, or facing a problem while uploading the code

1.First Download the code from the link below. Now open Arduino and Go to File~New.

2.Now a new window will appear. Next, Delete all the existing code and Paste the given code.

3.In the code, you will find Additional Board Manager URL now copy the URL and do the next step. For Different OS you have a different option. MAC: Go to Arduino ~ Preferences Windows: Fille ~ Preferences

4.Now Paste it in the Additional Board Manager URL section and press Ok. Now go to Tools ~ Board ~ Boards Manager Search for ‘ESP8266‘ and install the latest version.

5.After the installation Then go to Tools ~ Board and then select the ESP-12E Module. So, The Board is selected Now.

6.Next, Select the Right COM Port.

7.Then compile the Programme First and then Upload it to NodeMCU. After a few seconds, the code will be compiled and then Uploaded to NodeMCU Car.

The link you have to paste on Arduino IDE

Step 5: Electronics Part

in this part, I have simply soldered the components with the PCB board by JLCPCB and connected the wires according to the connection diagram.

Step 6: Mechanical Part

Here in this part, I have made the robot body using PVC pipe. To give a perfect shape, I have first straightened the PVC pipe by applying heat over it. then is have attached all the parts using instant glue.

here I have used a mobile stand to attach the mobile with the robot easily

I have also attached a plastic box to make a space to put something inside the robot
