Analyse how motion, force and energy are used to manipulate and control electromechanical systems when designing simple, engineered solutions (ACTDEK031)

Elaborations
  • investigating influences impacting on manufactured products and processes such as historical developments, society, new materials, control systems and biomimicry, for example the development of velcro
  • experimenting to select the most appropriate principles and systems on which to base design ideas, for example structural components to be tested for strength
  • calculating an engineered system’s outputs, for example speed, brightness of light, volume of sound
  • producing prototypes and jigs to test functionality, including the use of rapid prototyping tools such as 3D printers
  • using code to control systems, for example code to program a microcontroller or a simple, object-based coding application to program a system such as a remote-controlled car or simple robotic arm
  • investigating components, tools and equipment, for example testing the durability of batteries, determining the effective range of wireless devices
General capabilities
  • Numeracy Numeracy
  • Critical and creative thinking Critical and creative thinking
