  • 4X4 IN SCHOOLS: GETTING STARTED
  • WHAT IS 4X4 IN SCHOOLS?
  • Push classroom boundaries and venture into new STEM learning terrains. The challenge requires students to work in teams of 3 – 6 members to DESIGN, BUILD, CODE & DRIVE a remotely controlled four-wheel drive vehicle around our special 4x4 in Schools Challenge terrain course.

    The challenge requires students in Grades 8 – 12 to work in teams to design, build and code a remotely controlled four-wheel drive (4x4) vehicle. It must successfully navigate and complete obstacles on a special scale test track which is just as demanding as a real off-road situation, emulating the capabilities of a full size 4x4 vehicle. The competition has a strong emphasis on electronics, coding and programming, with students challenged to innovate, using sensors and vehicle control systems on an Arduino platform along with mobile app development.

  • THE BASICS
  • 4X4 in Schools can seem overwhelming at first glance however it is much easier to get started than it may first seem. Below, we have broken down the program into simple steps. 

    EQUIPMENT

    You will need the 4x4 in Schools starter kit which can be purchased from Yas in Schools. The kit contains the rock crawler vehicle and all the electronics you will need. Further details about this can be found below.

    All of the code and 3D printed parts are provided by us and are downloadable on the right hand side of this page. We however encourage students to modify and/or come up with their own solutions. 

    COMPETITION ELEMENTS

    The 4x4 in Schools Vehicle

    • Customised car body - various approaches to this can be taken, refer to regulations 
    • Tilt sensor with alarm - electronics and code provided
    • Automated headlights - electronics and code provided
    • Automated tow bar - electronics and code provided

    Team Pit Garage

    • Optional marketing display 

    6-minute Verbal Presentation 

    • Content and format described in this document and scorecards 

    The Vehicle Tests

    1.     Terrain Challenge – Development and Professional Category teams must navigate their vehicle across the various standard track elements within a set time limit. 

    2.     Trailer Tow Challenge – Development and Professional Category teams will need to put their automated tow bars to the test. Reverse and hitch to the standard trailer as fast as possible, then navigate the trailer tow course, including a reversing test, within a set time limit.
