Requirement Analysis:
The use of technical or mathematical models, simulations, algorithms, or scientific principles and procedures to determine whether a built product meets its specified requirements.This comes under system level This is first step in the verification process, the requirements of the system are collected by analyzing the needs of the users. This phase is concerned with establishing what the ideal system has to perform.Here, the users are interviewed and a document called the user requirements document is generated which is stated above.This document will typically describe the system's functional, interface, performance, data, security, etc. requirements as expected by the user.This document would serve as the guideline for the system designers in the system design phase. The means through which information is collected are interviews, questionnaires, observation. Each of the requirements in list is verified from built product to ensure complete satisfaction of customer

System design
The process of defining the architecture, components, modules, interfaces, and data for a system to satisfy specified requirements is done in system design.Here analyzing and understanding of the system is done by studying the user requirements document. Then checking for the probability and techniques through which this requirements can be implemented. If any of these requirements are not feasible, the user is informed of the issue. Again solution is found and the document is edited accordingly.Through continuous check for possibilities & techniques the selected list is:-
Components:

Toradex Apalis T30

Load carrying capacity
With the help of established technical or mathematical models, simulations, algorithms, or scientific principles and procedures, to determine whether a work product meets its requirements

Electrical Requirement Analysis

Motor Driver module
Line following module
Orientation module
Obstacle detection module
The use of established mathematical models, simulations, algorithms, or principles and procedures to determine whether a work product meets specified requirements

Software Requirement Analysis One part of software is in the main system and other part in the Toradex board. With the help of algorithms and procedure it is checked whether requirements are satisfied.

Mechanical Module Design It is a design approach that subdivides a mechanical system into smaller parts called modules that can be independently created and then used in different systems.The basic idea of modular design is to organize mechanical device as a set of distinct components that can be developed independently and then plugged together.
