Plants Watering Robot

Hi there, I am sarthak mishra.

I have made a project named plants watering robot, it is quiet autonomous as all you need to turn on the switch and after that leave the remaining work on it.

You also can subscribe my youtube channel from here-Khurafati BABA

Now let's talk about the working of this robot-

Initially it will be moving forward in a straight line, it'll stop whenenver detects the flowerpot from the ultrasonic sensor which is placed on the sideways of the wooden block.

After that the arm will start moving downward untill it finds the soil in the flower pot.

whenever the ultrasonic sensor reached the soil then the moisture sensor will start working and give the moisture value to the arduino, according to that value it will give water to the plant.

If the soil is not having the enough moisture- It'll give water to the soil untill the moisture level reached the optimum level. when the moisture is good enough then the robot will leave the flower pot and will start checking the another one.

If the soil is having the enough moisture- Then the robot will ignore that flowerpot and start checking the another flower pot.

1- Arduino UNO

2- 100RPM geared motor

4- Wheels

5- Screws

6- Clamps

7- Plastic rod

8- Battery holder

9- L293D sheild

10- SG90 servo motors

11- Dc pump

12- Ultrasonic sensors

13- TP4056 charging module

14- Moisture sensor

15- Jumper wires

16- Li-on batteries

17- Wooden box

18- Plastic container

Tightens the screws, makes the clamps fixed

Place the motors in between the clamp and then tight the motor's screws

Tightens the wheels' screws to fix the wheels on motor

With the help of gluegun. Stick the ultrasonic sensor on the wooden block

In the corner of wooden block, fix the bateery holders with the help of gluegun

On the tip of plastic rod, fix the ultrasonic sensor and moisture sensor with the help of gluegun.

At the end of this plastic rod, fix the shaft of both the servo motor with the help of fevi quick or gluegun

stick the servos on the top of wooden block with the help of gluegun

Join the pipe with the motor by heating the pipe a little bit.

Fix the pipe on the arm with the help of gluegun

solder the wires on moters and pass all the wirs through the hole.

Place the L293D shield nearby the battery holders.

Make a hole on the top of wooden block to paas the wires of servo motor, moisture sensor and ultrasonic sensor. To the L293D sheild.

Stick the TP4056 module and a switch on the sideway of the wooden block.

You can give any colour to this robot according to your mood.

Now, you are ready to rock with this exciting robot.
