Introduction: A MicroBit Crash Test Car

In this project, we are going to investigate, design prototype and test crash safety devices, either using an egg or a MicroBit as a data logger

Supplies

You will need:

  • A bunch of Lego, including wheels and axles, to make a vehicle capable of carrying an egg
  • a 3D printer
  • 3D CAD like Fusion 360 or TinkerCAD
  • A MicroBit (v2)

Step 1: Make a Crash Test Vehicle

The first stage is to make a vehicle you can roll down a slope to crash into a wall. You can design your own but it will need (1) an area to hold an egg or a MicroBit and (2) something protruding from the front to attach your crumple zone to the chassis

Step 2: Creating the Bumper Base

Create a sketch as per the dimensions, and extrude it 10mm

Step 3: Design Your Crumple Zone

On a new sketch create the design you want for the crumple zone and extrude it by 10mm

Step 4: 3D Print It and Test It!
