Multi-media Car

Abstract

The aim of this project is to build a self-driving car which can automatically avoid big barriers and obstacles in its path.

Objectives & Introduction

Show list of your objectives. This section includes the high level details of your project. You can write about the various sensors or peripherals you used to get your project completed.

Schedule

Show a simple table or figures that show your scheduled as planned before you started working on the project. Then in another table column, write down the actual schedule so that readers can see the planned vs. actual goals. The point of the schedule is for readers to assess how to pace themselves if they are doing a similar project.

Week No.	Start Date	Planned End Date	Task	Status	Actual Completion Date
1	04/06/2015	04/12/2015	Interfacing motors with SJone board, building the power circuit design	Completed	N/A
2	04/13/2015	04/19/2015	Interfacing infrared sensor and ultrasonic sensor, using the feedbacks to control the motors.	Completed	N/A
3	04/20/2015	04/26/2015	Writing functions of motors(including turn left&right&forward&revesre), verify the accuracies of those functions.	Completed	N/A
4	04/27/2015	05/03/2015	Implementing three ultrasonic sensors, and using the feedbacks to achieve the car can automatically find its own path when counter obstacles.	Ongoing	N/A
5	05/04/2015	05/10/2015	Depending on the previous function, adjusting the motors control module to ensure the car keep going straight in the case of no obstacles.	Ongoing	N/A
6	05/11/2015	05/17/2015	Assemble all the features together, use multi-tasking to connect all equipment as a unity.	Ongoing	N/A
7	05/18/2015	05/23/2015	Check all the details and prepare to demo.	Ongoing	N/A

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

Schematic of the design

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.

Power circuit is a series of batteries, which provides 7.5V power supply.
Motor controller, which is the H-bridge circuit, communicates with SJone Board. When the power supply of H-bridge is between 7-12V, one of its pin can be use as a 5V power supply. H-bridge has two sets of GPIOs to control different motors. Each set has two GIPOs, one for moving forward, another one is reversing.
Infrared sensor is used to detect any obstacles in front of the car, an interrupted will stop the car immediately.
Ultrasonic sensors are triggered by the high pulse sending by SJone Board and gives the feedback back. We can get the distances between obstacles and the car by calculating the length of those feedbacks.

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 pseudocode 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.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?

H-bridge has two sets of GPIOs to control different motors. Each set has two GIPOs, one for moving forward, another one is reversing.
-For the power circuit, we installed 5 batteries(1.5V/each) in series to build our power supply.
+* Infrared sensor is used to detect any obstacles in front of the car, an interrupted will stop the car immediately.
- The power circuit of our design are
+* Ultrasonic sensors are triggered by the high pulse sending by SJone Board and gives the feedback back. We can get the distances between obstacles and the car by calculating the length of those feedbacks.
-We have used the GPIO pins to control the DC Motors using the SJ One Board. For the Motor Control circuit we utilized a device called the H-bridge, an electronic circuit used to control the motion of the motors, ie., forward or backward. We utilise the GPIO pins to deliver a HIGH signal, which in turn runs the motors.
