THE COMPONENTS THOSE WILL BE NEEDED ARE

• ARDUINO NANO WITH CABLE
• L298N MOTOR DRIVER
• HC-05 BLUETOOTH MODULE
• M4 DIODE
• RED LED
• 78M05 VOLTAGE REGULATOR
• 220uF CAPACITOR
• TERMINAL BLOCKS
• HEADER PINS

Step 1: Why Automatic/Robot Home Maker Is Needed

There have so many robots are already available in the market who can clean the home, provides security protections, entertains people and many more. In case of my one, it is specialized in working side by side a person like other person works. Like, if you are cooking but on the same time you have to send a cup of tea to someone else, then the robot will carry the cup of tea to the other person. This will reduce work stress by working with a person. This will also use in hotels and restaurants in replacements of waiters.

Step 2: PARTS OF THE PROJECT

To make and understand it easily we have splatted this project into two main parts.

• MECHANICAL Part
• ELECTRONICS Part

for better explanation we have divided our ELECTRONICS Part into

• Circuit and PCB
• Assemble the electronics components
• ARDUINO coding

Step 3: MECHANICAL PART

Here in this part we will need some PVC sheet to make the chassis, 4 TT gear motors with wheels, 1 submersible pump, one cooldrinks can which is completely optional. you may use anything else to make the water tank. This is considered as the easiest part of this robot. All you need to only cut the PVC sheet and assemble all the components together in a proper way. Here I have attached some pictures on this.

Here I have used 60rpm TTgear motors but you may vary the rpm according to your need. But one tips I want to share that, lower rpm motos are easy to control & they could be shown easily in any resentation. Thats it for this part. now we will move to our next part which is ELECTRONICS PART. Here we will directly enter into the circuit and pcb making part. This could be littlebit tough if you are a fresher in making electronics project but I will explain is as much easier as possible.

Step 4: CIRCUIT Diagram & PCB MAKING

Here I have attached the circuit or the connection diagram which is very easy to understand and make. Please follow this diagram when you are going to make this project.

This project will work or perform same with or without making pcb but I have made PCb boards for this project. Actually not only for this, I always do prefer making any project using Customized PCB boards. There have obviously some advantages of making any project using PCB boards. like

• Compact Size and Saving of Wire.
• Ease of Repair and Diagnostic. If in case of any damage, it's very easy to check and replace the particular failure components.
• Saving of Time.
• Immune to Movement.
• Tight connections and Short Circuits Avoided.
• Low Electronic Noise.
• Low Cost.
• Reliability.

So I always make PCB BOARD for my every project. As I have already mentioned before I have already attached a circuit diagram with this article so please download that before you are going to connect all of them together. In my case, I have made a customized PCB board from JLCPCB to skip a few steps of wiring and make an easy connection between all the components.$2 for 5pcs PCBs, PCBA from $0, Register to Get Free Coupons here: https://jlcpcb.com/IYB. I really liked the PCB Boards as they are very high in quality.

Step 5: ASSEMBLE THE ELECTRONIC COMPONENTS

Now we will make all the components together. But before that please make sure that you have gathered all of them correctly. Here I have enlisted the components and also provided their pictures for your references. Hope this will help you to make this easier.

SO THE COMPONENTS THOSE WILL BE NEEDED ARE

• ARDUINO NANO WITH CABLE
• L298N MOTOR DRIVER
• HC-05 BLUETOOTH MODULE
• M4 DIODE
• RED LED
• 78M05 VOLTAGE REGULATOR
• 220uF CAPACITOR
• TERMINAL BLOCKS
• HEADER PINS

Now please assemble all the components together to complete the project. this is very easy to do if you follow the simple connection diagram. But if you have any doubt on this you may watch this video for better understand
