This document summarizes a project on Agrobot undertaken by students at Yeshwantrao Chavan College of Engineering under the guidance of Mr. Amit Tripathi. The project aims to develop a robot that can help with various agricultural activities like seed sowing, fertilizer spraying, and weed removal to increase efficiency and sustainability. The robot will use an 89c2051 microcontroller, path sensing circuits, motors controlled via an L293D driver. It is meant to work across different weather conditions and navigate around obstacles in the field. Agricultural robots have applications in tasks like sheep shearing, field sowing, fruit picking and more.

3. Agriculture has been India's primary source of income and employment.
The current technology available cannot be used across activities.
Only traces of technology seen in agriculture are tractors .
Seed sowing, fertilizer spraying and weed removing carried manually.
Sustainability of resources is the need of the hour, and hence alternative and
renewable sources of energy, coupled with mechanization of time consuming
activities will ensure better output.

11. : Operating the L293D motor driver
L293D motor driver, makes controlling a motor as
simple as operating a buffer gate IC.
Isolates the TTL logic inputs from the high current
outputs.
Putting a logic 1 on the pin In1 will make Out1 pin go
to Vpower (36 Volts MAX.)

12. MICROCONTROLLER
Microcontrollers are used in automatically controlled products and devices,
such as automobile engine control systems, remote controls, office machines, appliances,
power tools, and toys. By reducing the size and cost compared to a design that uses a separate microprocessor,
memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and
processes.

14.  Time and manual power is reduced.
 Fewer errors and at higher speeds.
 used in various fields like agriculture, medicine, mining, and space research.
 It can be sent to another planet to study their environmental conditions.
 The machines could easily work around trees, rocks, ponds and other obstacles.
The robot will be able to exposed in different weather conditions.

15. Robots have also found some applications in agriculture.
1. In Australia a robotic system has been developed for sheep
shearing
2. Robots for field sowing
3. Raisin and apple gathering
4. Mobile robots can be envisioned performing such work as
irrigation, harvesting, cultivating, planting, spraying and field
inspection, and as guardians of animal welfare.

There are many other potential benefits of mobile robots. Some
of these are:
* better quality of work;
* increased productivity;
* fewer human accidents;
* fewer demeaning jobs for humans
