  • 3. Topic this year
    • Robot Car Race – Augmented Reality
    • To enable first person experience in a real car race
      • Not just a computer game, real robot cars are racing and controlled by you
      • Control a robot car as if sitting inside the car
    • Augmented reality (AR) is a field of computer research which deals with the combination of real-world and computer-generated data
      • Different from Virtual reality (VR) – simulate the real world by computer-generated data
    • In this project, live video will be combined with 3D graphics in a robot car race
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 4. Things to do
    • Learn the features, working principle and implementation methods of different sub-systems required in this project
      • A series of lab exercises will guide you to achieve the minimum of the project requirement
    • Find a partner to form a group
    • Compete in the qualifying round of the robot car racing
    • Summarize the experience and devise better solutions to improve the performance of your car
      • You are asked to prepare a progress report to indicate your plan
    • Improve your programs and compete in the final round of the robot car racing
      • You are also required to make a presentation and a final report (Web page) to elaborate your improvement work and the result
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 5. Rules of the Game
    • Each team is provided with a LEGO Mindstorms Robot Car

    • Comprise 3 major components:
      • SEU – System Electronic Unit
      • Receptors
      • Wireless Markers
    • Markers’ P&O will be detected
    • by the Receptors and processed
    • by the SEU
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun

        • Manpower
        • Time
        • Lab facilities
      • Need to specify the approach in resource management in the final report and presentation
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 26. Why project management?
    • A project involves the interaction of different parties
    • A project will be successful only if all parties do their job right
    • By having good project management, we can
      • Achieve the project goal on time and within the budget
      • Keep customers (e.g., Professors) happy
      • Keep the team focus on the goal and work well
      • Everyone shares the load
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 27. Scope, Resources, Schedule & Customers Project Management
    • Project Planning
    • Define objectives / requirements
    • Define work/tasks
    • Identify resources
    • Plan schedule
    • Iterate
    • Plan modification
    • Execution Management
    • Get objective signed-off
    • Track plan progress
    • Communicate within team
    • Customer communications
    • Secure resources
    • Project discipline
    Technical People Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 28. Project Planning
    • The process of project development is full of uncertainties
    • The more uncertainties you have, the less possible that the project can be successful
    • Uncertainties can be reduced by having a good feasibility study before the project
      • Background research
      • Understand the resource required and acquired
      • Risk analysis
    • The feasibility study has been prepared for you in the lab exercises
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 29. Requirement Analysis
    • The purpose is to identify and document the exact requirements for the project
    • Much interaction must take place between the customer (e.g. Professor) and the developer (e.g. students)
    • Should be well documented since very often it serves as an agreement of the functions that will be provided by the system developed
      • The document is sometimes called user specifications or functional specifications
      • May form the basis for project commissioning
    • Your progress report should contain the above items
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 30. System design and specification
    • Split into two sub-phases: architectural and detailed design
    • Architectural design
      • Define the overall organization of the system in terms of high-level components and their interaction
    • Detailed design
      • Lower level modules in each component and their interfaces
    • Example: In software development
      • Architectural design – the function and relationship of classes
      • Detailed design – the internal modules and interfaces of each class
    • Should be well documented
      • The document is sometimes called technical specifications
    • Your progress report should contain the above items
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 31. Implementation – Work breakdown
    • Split project into tasks and estimate time and resources required to complete each task
    • Organize tasks concurrently to make optimal use of workforce
    • Minimize task dependencies to avoid delays caused by one task waiting for another to complete
    • Should be detailed in the progress and final report

  • 33. Resource Management
    • About how to manage the manpower, time and facilities required in the project
    • Some bad practices of students:
      • “ We didn’t allocate task to members since we work together all the time.”
      • A very bad practice. Will get very low marks in project management
      • “ There’s not a leader in our team. We always make decision together.”
      • For small team, the role of leader may not be very obvious. But I would still suggest you to find a leader in the team so as to practice the way of managing large projects. Besides, it can also give you convenience particularly if there is dispute among members.
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 34. Resource Management
      • “ My team member didn’t do anything. I decided to leave him alone. The work submitted was done by me.”
      • See, finding suitable manpower is very important. That team member certainly will fail, since team members will be individually assessed. The marks of the group in project management will also be deducted since the project leader failed to estimate the risk at the planning stage and make appropriate contingency measure.
      • “ The demo is tomorrow. I have finished everything at home already today. I just need to change the IP address in the program then it will run in the lab.”
      • Last year many students tried this but found that at the end the program simply could not compile and run. Remember, unless you have seen your program ever run correctly in the lab, never assume any result you get at home can be repeated in the lab.
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 35. Resource Management
      • “ It is very troublesome to book the Interactive Multimedia Lab. We plan to do the project at home.”
      • Last year many students failed to deliver their project just because they did not spend enough time in the lab. There are many sub-systems in the project that their realization can only be done in the lab (DE505a). This year we will count the time that the teams spent in the lab as one of the assessment criteria for project management.
      • “ Our team was very busy in many different things so we skipped all the lab works. But we managed to use the last week to finish everything and made a good demo of our robot.”
      • Assume that you are doing this project for your customer. If I were the customer of your project, I would never hire your team to do project again! All customers want to see both progress and result. So your marks in project management will be deducted.
    Department of ELECTRONIC AND INFORMATION ENGINEERING Introduction by Dr Daniel Lun
  • 36. Some Useful Advices
    • The lab exercises serve as the background studies to prepare you to finish the project
      • Not an extra work but a part of your project
      • Remember to finish them all by yourselves
    • Don’t wait until the last week to do your project
      • Software will not work if you develop it in a rush
      • Many teams failed to do the demo last year just because of that
    • This is not a computer science project but a computer engineering project
      • Is not implemented with your computer only
      • Involve many sub-systems that may not work as you desired if you don’t really try them in the lab
