1.2 ABOUT ENGINEERING EXPLORATION:

The opportunity to explore materials and discover their potential is constantly evolving. An inquisitive and curious mind is needed to ensure that materials continue to push creative boundaries while still remaining functional under the decorative we deal with the project using components of mechatronics.

The goal of this module is to move from defining the problem to designing a solution. We begin by learning about the exploration phase, and we will exit this phase with a number of design concepts for peer review. We also learn how to decompose a design to evaluate its overall function and essential process in creating a good design essential to the life of our design. Finally, we learn how to critically examine past design artifacts to inform our current concepts so that we can sensibly differentiate our product.

From this, we build trust among our teammates, which also helps in the personality development and with individual self-confidence and co-ordination among us.

1.3 Pertinent Information Gathering

Need Statement

Due to lack of labour and to increase yield, few agriculturists in a village want to go for mechanization of various farming processes. Now they need automated solutions for processes like seed sowing, plantation, and harvesting.

1.3.1 Introduction

We already have many technologies which allow us to plant seeds on farms. The problem attached with this is that, despite the technological advancement, major types of these machines include manual labour. There is a lot of potential for the development of the said machines in both large-scale and small-scale farming. By using existing technologies we can design and implement automation in these areas of farming.

1.3.2 Goals

The goals of this project would be to:

• Implement existing knowledge along with new research to integrate automation in the seed sowing sector of agriculture
• Create a semi or fully automatic machine which does the work of sowing seeds in either a field (large scale) or in pots (small scale)
• Easily sow different seeds in pots, starting with adding soil, seeds, etc
• Make it portable, and economical so that it reaches a wider section of the agricultural industry

1.3.3 Proposed System

A semi-automatic machine that sows seeds in pots in a row. This machine will be helpful in gardening and in nurseries and places where small plants are grown. The machine should be able to plant seeds in pots one after the other. The machine should take care of adding soil, and seeds, and then covering it. This machine should be portable and economical. Another idea for a machine would be sowing in a field where the soil is plowed before sowing the seeds. This machine can be controlled by a mobile app, to select the type of seed to be sown.

1.3.5 ELECTRONIC COMPONENTS

Sl.No	Components or parts used	Working principle	Images
1.0	Arduino Mega 2560	The Arduino Uno board is a microcontroller based on the ATmega328. It has 14 digital input/output pins of which 6 can be used as PWM outputs, a 16 MHz ceramic resonator, an ICSP header, a USB connection, 6 analog inputs, a power jack, and a reset button. This contains all the required support needed for the microcontroller.
2.0	Bluetooth HC-05	Module to integrate machine with a Bluetooth compatible device(in this case a mobile phone
3.0	2 channel relay	2-Channel 5V Relay Module is a relay interface board, it can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on. It uses a low-level triggered control signal (3.3-5VDC) to control the relay. Triggering the relay operates the normally open or normally closed contacts.
4.0	60 or 30 RPM DC motor	An electric motor operated by DC (direct current) is known as a DC motor (unlike an induction motor that operates via an alternating current). A DC motor converts DC electrical energy into mechanical energy.
5.0	Servo motor	Servo motor works on PWM (Pulse width modulation) principle, which means its angle of rotation is controlled by the duration of applied pulse to its Control PIN. Basically servo motor is made up of a DC motor which is controlled by a variable resistor (potentiometer) and some gears.
6.0	Foam board	Foam board or Foam core board is a strong and lightweight material that is easily cut with a sharp craft knife or picture framing mat cutter. It is commonly used to mount prints and photographs and as backing in picture frames. Foamboard is easily formed into shapes that can be used for interior design and architectural models. Foam board usually consists of three layers, an inner layer of polystyrene or polyurethane foam that is clad with an outer facing on each side of either a white clay coated paper, cotton archival paper, or common brown Kraft paper
7.0	5V Adaptor	An AC adapter, AC/DC adapter, or AC/DC converter[1] is a type of external power supply, often enclosed in a case similar to an AC plug.AC adapters are used with electrical devices that require power but do not contain internal components to derive the required voltage and power from mains power.
