1. Principles and practices

My final project

For my final project I would like to make a sensor operated bump-and-go car. But wit a difference. The traditional bump-and-go car has to bump against a wall or an object to change direction. Mine will be sensor operated. So it will not bump against an object but change directions at a certain distance from the object.
This toy car will be for playful people from 8 till 88

View from the side, although this looks to car’ish. I would like to give it a more abstract shape.

View at the bottom. This is how I think I should organize the driving, steering, power and electronics.

What do I have to research for this project?

  • Material for the car, wheels, and axes
  • Gearing from motor to ax
  • Steering mechanism
  • Servo motor for steering
  • Micro USB rechargeable battery
  • Electronics such as distance sensor

And off course all the machines to make it.

Other ideas

  • A hydroponic system
  • A lamp that rises out of a box when it gets dark
  • A flip book machine
