Swarm Robots
Abstract
Swarm robots deals with coordination of multiple robots. The collective behavior of the robot swarm emerges from interaction with each other and surroundings. All the Robots can communicate with each other. The position of each robot is determined and monitored by an overlooking camera. Large number of simple robots can perform complex tasks in a more efficient way than a single robot, giving robustness and flexibility to the group.
Objectives & Introduction
- Initially all robots will go in search of the target, as and when the target is located, the bot which is near the target sends out a message about its present location to all other bots.
- Overhead camera serves the purpose of determining the location of individual bots.
- Once the message regarding the target position is received by other bots, each of them will move towards the target.

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# | Date | Task | Actual | Status |
---|---|---|---|---|
1 | 4/14/2015 |
1) Hardware - Design of Motor Controller, Robot assembly 2) Software - OpenCV environment setup, Basic video processing |
1) Hardware, OpenCV setup - Completed Problems Encountered - Hardware Bug discovered in version 0.1 of motor controller circuit after testing. 2) Software - Problems during filtering video for certain colors. |
Completed |
2 | 4/21/2015 |
1) Communication between OpenCV to SJone board using DB9 connector and UART3 2) PWM and Ultrasonic sensor drivers 3) Object detection and mapping 4) Wireless communication between two nodes |
1) Modification of RS232 header file to support windows 7 file API. Was not able to communicate between OpenCV and SJone board using UART0 2) Unable to receive the echo signal and was not able to use ultrasonic sensor without interrupt. 3) HSV values had to be detected to recognize particular color. Had difficulties to find the HSV values for a color. This was solved by writing a program to print the HSV value of the color that is pointed in the video. 4) Packet sending and recieving failure. System crash while transmitting and recieving packets |

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.
- Detection of robot -
This is achieved with the help of an overhead wireless camera. Camera access and detection of robot is implemented on a computer with the help of openCV library. Each robot will be updated with its present location.
- Each robot is of a different color. This will help in differentiating the robots from one another. Images from the camera are captured every
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?
Project Video
Upload a video of your project and post the link here.
