Car IoT

Scenario: A toy car with a light sensor should drive through a dark tunnel. The car should transmit position and light intensity information to server. A second toy car should drive the same route and when it arrives at the tunnel, it should light up its LED.
What I need:
  • A remote controlled toy car with LED, light sensor, computer and WiFi. Use Lego Mindstorms (LM) EV3.
  • A server that listens to and broadcasts light intensity data.
Version plan:
  • Version 1: Save data on LM.
    • Save data on LM. Use number of wheel turns to approximate distance travelled. How do you persist data on LM?
    • How to light up an LED with LM.
  • Version 2: Use (local IP), host server on your laptop.
    • How to transmit data from LM to server via WiFi.
    • How to get data from server via WiFi to LM.
  • Version 3: Use VPS and static IP.
  • Version 4: Access data from an Android smartphone.
  • Version 5: Use IMU to calculate distance.

Map for search and rescue operations

Tolga: Search and rescue personel have categories like 7 year old child etc. These categories define typical behaviour of the victim. For example, if it is a 7 year old child, it will not stay where it is and move at a certain speed.

It would be helpful to have a tool that
  • Works without internet connection
  • Draws map
  • Lets the user input 
    • victim category
    • victim location 
    • time passed or time the intelligence was obtained (time passed = current - obtained)
  • Draws estimated location circle with radius according to category and time passed
Research:
