IOT Smart Car aka MBED Based Remote Temperature Sensor

Introduction

This project is about demonstrating an IOT application using MBED Application borad LPC1768. In this project a toy car has been hacked for demonstrating a remote sensor. According to Oxford Dictionary defination of a "Robot" is a machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer. This toy car according to the defination of a robot does fall in the category of being a robot therefore in the next sections the car will be refered with terminoligies as "Robot Car" or "Robot".

Goal

The goal of the project is to make a Robot that:

  • Can act as a Smart remote sensor by updating sensor data via Ethernet and Wifely Interface.
  • Can be controlled or accessed from a remote position using various interfaces. Functionallity: As this project is done for educational purpose rather than for comercial product therefore our team tried to use all bits and pieces of what we have learnt in the class to implement in this project. For clear vision the functionality of the Robot is broken down into different modes(a manner of acting or doing). The modes of the Robot are as follow:

Testing

Wi-Fi Control of the Remote Car

IDTest Case DescriptionExpected ResultActual Result ObtainedTest Status
1Connect the Wifi Module to the mbed and power up the mbed placed on the car. Verify the wifi that is used in the code is turned ON and the control machine should be on the same network. Press reset on the mbed.The mbed wifi should get an IP address which will be displayed on the LCD.The wifi module gets an IP address that is on the same subnet as of the control laptop.PASS
2When you get an IP address on the LCD telnet to the IP address from your control computer. Use port # 7 for the telent.The connection should be established.Connection SuccessfulPASS
3The Control Keys for the car are
Forward -> 'w'
Reverse -> 'x'
Left -> 'a'
Right -> 'd'
Make the wheels straight -> 'z'
