THE BRIEF/INSTRUCTIONS

The following Learning outcomes will be assessed in this assessment

· 1. Develop appropriate software solutions to technological problems.

· 2. Describe and apply features of an object oriented programming language.

· 3. Effectively exploit the programming language and development environments.

· 4. Effectively apply software design and development principles.

Overall Aim.

To implement a software system in C#, that can read and write data in standard XML, store and retrieve data from an SQL database in a user friendly manner.

Assignment Aims

Students will be provided with the following software (on blackboard) :

An SQLite database file.

The aim of the coursework is to give students practical experience in object oriented software development by implementing a system in an object oriented language (C#) that involves a number of real-world engineering applications (reading and writing standard data format (XML), database access and storage, user interface design).

The System.

A company has developed an autonomous robot system that has the capability to deliver small to medium sized objects over a short distance. The robots are to be used in a large warehouse environment to move small parts, tools, orders etc. An empty robot can travel for 1000m before it has to re-charge, for each 5kg the robot carries it operates 5% less efficiently E.G.

Empty / lightly laden robot (0 - 5.0kg) can travel for 1000m.

Therefore a robot carrying 5.1 to 10.0kg

100% / 95% = 1000 / x. x = 950 therefore a robot operating at 95% efficiency could travel 950m

At 95% efficiency 1% of battery moves the robot 950 / 100 = 9.5m

Or moving 1m uses 1/9.5 = 0.1053% of the battery (rounded to 4 decimal places)

The maximum weight a robot can carry is 25.0 kg. It is assumed that size is not an issue.

All robots always move at their maximum speed of 5m/s regardless of cargo weight.

The warehouse is assumed to be a simple square, 100m along each side. There is a re-charging station in each corner and robots are assumed to be able to move in a straight line at all times and never collide.

A full charge of a robot (robots never charge less than fully) takes 3 minutes. Robots will recharge during a job but not between jobs.

The company owns 5 of these robots.

The student is supplied with an empty SQLite database, on Blackboard, containing three tables, Jobs and RobotHistory, RobotStatus.

The Tables are as follows:

Jobs
JobID	StartPos	EndPos	Weight	Complete

JobID – Primary key, Integer – Uniquely identifies a Job.

StartPos – Text – Starting point for the job where the object is collected.

EndPos – Text – End point for the job where the object is delivered.

Weight – Real – Weight of the object being transported.

PREPARATION FOR THE ASSESSMENT · XML file handling was covered in lab 12 · Database access / SQL was covered in labs 13 and 14, students should use the code given in these labs for this work. · Students will be given time during lab sessions to work on the assignment with guided assistance. · The assignment will be explained and students given the opportunity to clarify any points in a lab session, and the recording will be placed on Blackboard.

Marking Grid

	< 40% (Fail)	40-49 (3^rd Class)	50-59 (Lower Second class)	60-69 (Upper Second Class)	70+ (1^st Class)
Documentation	Some aspect of the documentation is missing (Design, testing, improvements or user guide).	Basic program design. Testing limited to checking program is in a compliable state. Improvements limited to aspects that could have been done by the student. Program features missing from documentation.	Program design may not fully explain all aspects. Some parts of testing are missing or not fully covered. Simplistic improvements. Some aspects of program may not be documented.	Program design covered well. Good testing plan that covers most aspects. Some improvement ideas. Program features fully explained.	Excellent design documentation (UML, data flow etc.), Full testing plan that covers all major aspects, innovative improvement ideas. Program fully explained.
Program	Program has severe problems and is missing major features of the specification. Program may not compile as supplied.	Program can save XML, load XML, and update the database. May not handle file issues without crashing. May use poor programming style. A program with significant work that does not compile can not gain a mark higher than this.	Program performs all the main functions (save, load XML, update and simple database query). The program may not perform all the advanced functions such as calculating the robot path including charging.	Program performs all the specified functions. There may be some small program flaws that do not affect the overall running of the program.	Program works as specified without any issues (handles file issues without crashing, prevents changes to the database through SQL interface etc.). Additional marks can be gained for innovative design and features.
