Laser Guided Vehicle using MATLAB

This MATLAB project mainly depends on the border of the roads. Here we use two coordinate lasers which will increase the strength of road detection. The procedure was developed by using JAVA and MATLAB, using a sequence of scan recorded on roads. The road detection uses the Hough transform for each scan. The control law is based on the “dog-rabbit principle”.

Introduction:

We mainly come across problems like a block on the roads. In order to avoid this problem, we remain using scanning laser titled downwards, a thread optic gyro and odometric encoders. Here the laser scans the blocks using Hough/Radon transform. The programming is mainly done in Java. Java methods are then combined in a MATLAB script. We use Java and Matlab because these are found to be excellent test-bed for designing and testing procedures. Now the problem we face while developing the project is that all the sensors should work in the sequence manner and should have a very small time delay. Once all the checking of sensors has been done, we have to concentrate on the navigation of procedure with the help of these sensors.

About the Scanning Laser:

The range of the scanning laser is about 80m. This laser can use angular of 5o over 180o. The update break of laser is 5Hz. The laser gives a new scan for every 0.2s.

Advantages:

• Direct Labour cost reduction
• Avoid workforce shortages
• Avoid mistakes
• Improve traceability and inventory accuracy
• Layout Freedom
• Modularity or Scalability
• Increased safety
• Improved ergonomics
• Minimize infection risk
• Indirect cost reduction
• Increase productivity

Disadvantages:

• Investment is very high. 
• Maintenance Costs.
• Not Suitable for Non-repetitive Tasks.
• Decreased Flexibility of Operations.

Implementation of Languages:

The implementation is done in Mathworks MATLAB 6.5.1. Matlab will support for Java. The exclusive parts of the computational can be made by using Java. Matlab is also a great tool for matrix calculations. It also gives great options for plotting data, for making graphs in both two and three sizes etc. The attendant software is written by using C++. The attendant communicates with Matlab through Java methods. New Java methods are easily executed. To make a new module that is based on anew procedure is easy to do. One of the disadvantages of Matlab is that it is slow since it is understanding the code, especially when using plot purposes. To speed up calculations it is possible to make the procedure in Java. If that is not sufficient there is possible to go another step and compile the java code to machine code. If this still is not enough there is something wrong/inefficient with the procedure or more computer power would be necessary.

Conclusion:

If this MATLAB project gets succeed we can able to get automatic vehicles which will run with the help of lasers and its procedures. And the scope of getting accidents will also reduce with the help of this project.
