1. Introduction

1.1 Purpose of the requirements document

This Software Requirements Specification (SRS) identifies the requirements for the RobotArm - Handicap

1.2 Scope of the product

The purpose of this project is to make a simulator to make possible the robot to reach a destination, espacially a real object :

- One part concerns the embodiment of the GUI and a description of the robot

- A second part concerns the communication with the robot

- A third part concerns the communication with the program of detecting markers with the other group

1.3 Definitions, acronyms and abbreviations

Python : Python is a high-level programming language which supports multiple programming paradigms, including object-oriented, imperative and functional programming

VPython : Vpython is a Python language including a library which allows programmer making a GUI in three dimensions more reachable than other languages

1.4 References

VPython : For Documentation

2. General description

2.1 Product perspective

The aim is to allow a robotic arm with five degrees of freedom to take an object previously detected and to bring it to a specific place. It will allow people with disabilities to take for example, a glass of water.

2.3 User characteristics

The users doesn't need to know something about programming or how the robotic arm works. The last one have to work automatically.

2.4 General constraints

Software constraint:

Installing VPython is a quite difficult on windows and complicated on Linux

Material constraint :

There is some problems with the robotic arm

2.5 Assumptions and dependencies

The robotic arm can be controlled by the simulator

3.Specific requirements, covering functional, non-functional and interface requirements

• document external interfaces,
• describe system functionality and performance
• specify logical database requirements,
• design constraints,
• emergent system properties and quality characteristics.

3.1 Requirement X.Y.Z (in Structured Natural Language)

Function: Help the camera to detect the marker on the object, localise the object on the simulator relative to the robotic arm base, take it and bring it back

Description: Implement a simulator to move the robotic clamp in spacial coordinates

Inputs: Webcam, marker on the object, a users which can move all the robotic arm to make the object reachable

Source:

Outputs: A persons with arm disabilities can take an object

Destination: All people, all object which can be taken by the robot (dimension)

Action: The simulated robot follows a path to find the marker

The detection program of the other groups give the displacement of the camera by sending data in sockets

The simulated robot take the object and bring it to a place

Non functional requirements:

Pre-condition:

Post-condition:

Side-effects:
