Design Brief

  1. Introduction

    The technology of computer generated images has influenced film makers and cinematography and dominated the production of action films for many years. However, the latest films involving high-performance vehicles, have extended the possibilities within the design envelope and created full scale working models for action scenes. Central to the production of the recent films of the Batman Trilogy was the creation of a new concept of vehicle using evolving car technologies and many creative design features derived from the former Batmobile vehicles. The unprecedented design challenges resulted in what is now an iconic creation, of ground breaking mechatronics engineering, called the Tumbler.

    Design a model Tumbler to the general specifications outlined below.

    The Tumbler should be your own unique design and should:

    (a) Have a rear wheel propulsion unit;
    (b) Incorporate an automated door for easy access;
    (c) Include a steering mechanism.

    Presentation of the completed model should ensure that:

    (a) All main operating features are clearly visible without dismantling.
    (b) The longest dimension of the model does not exceed 300 mm.
    (c) Electric power does not exceed 9 volts.

    Special note: The use of modified toys or model kits is not acceptable.

  2. Design Process (40 marks)

    A design folio must be compiled which will detail your :

    1. Analysis of the given brief and investigation of possible solutions;

    2. Criteria for selection of your own individual solution and production drawings/plans;

    3. Testing and evaluation of your design solution;

    4. Special instructions, if required, regarding the testing of the solution by the examiner.

    Note: Marks are awarded as shown in Marking Scheme (below).
    Computer-aided design (CAD) should be used where possible.
  3. Design Realisation (110 marks)

    Using appropriate materials, make the model according to your own individual design plans. Computer numerical control (CNC) technology should be used, where possible, to support manufacture. You are required to manufacture and assemble all the parts, subject to the following guidelines :

    1. Standard components may be used to support the assembly and interconnection of various parts;

    2. Unnecessary recycling will result in lost marks. Recycling will be acceptable only in cases where a complex part cannot readily be made in the school;

    3. Bought-in electronic solutions will result in lost marks;

    4. Adhesives, if used, should be applied sparingly.

    Marks are awarded as shown in Marking Scheme (below).

  4. Project Presentation

    Your completed project consisting of the model and design folio, both clearly identified with your examination number, must be available to the visiting examiner.

    Marks are awarded for quality of presentation and finished appearance of both the model and folio.
