 Agriculture Robots

The agricultural robot also known as the agro robot is designed and built to help people in agriculture. The robot could be of different sizes, different shapes, and different mechanisms. 

Homemade Agriculture Robot with multiple sensors


A smart farmer assistant robot uses a set of various sensors and processor, which combinedly
take various values from the field and determines the condition of the soil, weather and
gives required measures to be taken by the farmer. In automatic mode, the robot can
operate the field condition by itself, like operating the water pump, spreading fertilizer, or
pesticide in the required amount in the absence of the farmer. This robot communicates with the farmer’s mobile phone and sends regular feedback about the field condition.

This Smart Agriculture Robot demo video contains the working demo of the Smart Agriculture Robot.
This smart farmer assistant robot works with Arduino. Various sensors for soil, air, and water are attached to it, which feeds the required data to the Arduino processor. The Arduino processors then determine the condition and decisions to be taken for the specific field.

The robot sends primarily analyzed data to the mobile device or smartphone of the farmer,
so that the farmer can take immediate decisions. Again, the robot sends the data to
the agriculture research center, or in the central server, which further analyses the data with
machine-learning algorithm for getting future predictions and probable values and measures
to be taken for upgrading the agriculture sector.

There are 13 different types of sensors present in this Agriculture Robot. Accumulating all of its data,
the processor determines the accurate condition of the field. The sensors are:

1. Soil Moisture sensor
2. Sonar Sensor
3. Sound Detector
4. Gas and CO2 sensor
5. LDR
6. Motion Detector
7. Gyroscope
8. Raindrop Sensor
9. Water sensor
10. Air Humidity sensor
11. Weather temperature sensor
12. Soil Quality Sensor
13. Soil pH and Temperature sensor, etc.

1. Soil Moisture Sensor: Determines the moisture level and amount of water in the soil.

2. Sonar Sensor: Ultrasonic HC-SR04 sensor uses ultrasonic reflection to measure distance.
This sensor will help the robot in locomotion and detecting objects nearby.

3. Sound Detector: the Sound sensor detects nearby sound levels and the program
determines the weather condition or nearby animals using sound feedback.

4. Gas, CO2 sensor: Weather air quality is very important for any kind of cultivation.
This sensor determines the level of carbon dioxide, monoxide, presence of harmful
gases, or total air quality.

5. LDR: Light Dependent Resistor determines the day or night for irrigation.

6. Motion Detector: PIR Motion detector is able to detect the presence of any living
object, animal, or human being inside the perimeter of the field.

7. Gyroscope: X-Y-Z axis gyroscope is used to detect the tilt or rotation of the robot,
which contributes to the locomotion of the robot.

8. Raindrop Sensor: Rain is another most important factor in cultivation. This sensor
determines the presence of rain or the amount of rain.

9. Water sensor: This sensor determines the water amount in the field and controls the
irrigation pump accordingly.

10. Air Humidity sensor: Air moisture level plays a vital role in cultivation and weather.
This sensor determines the air moisture and temperature which is used to create the
weather forecast.

11. Weather temperature sensor: Weather temperature plays a role in controlling the
dryness or water level in the soil. This sensor gives accurate temperature value.

12. Soil Quality Sensor: The quality of soil, level of nutrients, minerals are very important for
determining the fertilizer to be applied. This sensor gives proper value for
determining the amount.

13. Soil pH Temperature sensor: pH level and soil temperature is also important for
the number of fertilizers to be applied.


This AI Farmer Assistant Robot is the future of agriculture. We cannot skip farming, as this is the prime source of our food. Again, due to technological advancement and various reasons, farmers are leaving this profession. So, for their assistance and as well as researching every field practically, we need this robot. This robot will be capable of sending very important sensor data to the central server, which will be the key to the future of agriculture. Using a machine-learning algorithm this system will draw very important information for further advancement of agriculture as well as saving the crops from unwanted natural disasters.
