The document provides a template of the Software Requirements Specification (SRS). It is inspired of the IEEE/ANSI 830-1998 Standard.

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
Python : For Documentation
VPython : For Documentation
1.5 Overview of the remainder of the document
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.
2.2 Product functions
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)
a. Markers detection
Description: The camera detect the marker on the object and locate it
Inputs: Video stream and markers
Source: ArUco library detection
Outputs: video stream with markers highlighted with their id and an xml file which contains the marker's id and the coordinates of the four points of the markers
Destination: All people, all object which can be taken by the robot
Action: The ArUco library detects borders and analyzes in rectangular regions which may be markers
Non functional requirements: The marker detection should be done in real time and faster
Pre-condition: Using the Creative Camera, ambient light should be enough to see correctly user´s movements. Using the leap motion, hands should be above the sensor. The recognized gesture is present in the data base.
Post-condition: The user hand movement has been well recognized.
Side-effects: Bad gesture recognition
