Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

Discuss your hardware design here. Show detailed schematics, and the interface here.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which Buses used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Software Design

Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Design & Implementation

The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.

Hardware Design

The sensor controller is the crux of the obstacle avoidance algorithm of the car.

It consists of four ultrasonic sensors connected to the LPC1758 board. We have used the MaxSonar MB1010 sensor as it provides a good balance between sensitivity and object rejection. Three of the sensors (left, center and right) are placed in the front and one sensor is positioned at the back.

Hardware Interface

In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.

Design & Implementation

The Geographical Controller is used to track the current location of the car. The module comprises of a GPS module and a compass.

Once the user choses the destination point on the Android application, the app will map the shortest path available from the current location to the destination and plot multiple checkpoints based on that. The coordinates of these checkpoints are sent to the GEO controller, which will calculate the distance between the current location of the car and the next checkpoint and the turn angle required to reach the next checkpoint and send this information to the Master controller.

Hardware Design

The GPS module used is SparkFun Venus GPS with SMA Connector [11]. And the Compass is CMPS11 compass [12]

Hardware Interface

GPS Module

SparkFun Venus GPS with SMA Connector
SparkFun Venus GPS with SMA Connector

The GPS Module used is SparkFun Venus GPS with SMA Connector based on Venus638FLPx IC. It sends out the information in standard NMEA-0183 format or Skytraq Binary sentence format. The default rate is 9600 bps and is configurable up to 115200 bps, with update rates up to 20 Hz.

We have configured the module to a rate of 38400 bps UART at 5 Hz. Skytraq GUI is used to configure the GPS module


The module outputs NMEA message in format of GGA - Global Positioning System Fix Data. Time, position and fix related data for a GPS receiver.
