Embedded Systems task ( 2nd Years)

Deadline : 10.sept.2015

The following things need to be done:

Make a Mod-11 (i.e. it must be a 4 bit counter) counter using FLIP FLOPs

The counter is assumed to be driven by an independent clock source which isupdated at 1Hz

Generate a signal on every odd value output of the counter

This signal should allow a LED to be lit for a period of 20ms.For this purpose, a

microcontroller must be interfaced suitably with the counter. The LED isinterfaced with the microcontroller.

Once the counter value reaches 11,the counter needs to be reset

For resetting the counter, the same interfaced microcontroller must be used

Conditions:

8051 microcontroller needs to be used

The signal given to MCU to light LED must be in the form of an interrupt

Other than the counter and the microcontroller, you are free to use any logicgates to implement the system

To do

Proteus Simulation of the suitable circuitry must be developed(use proteusversion 7 for simulation).

Find out the answer to this question “Apart from the usage of interrupt,what other method may be used to light lightthe LEDs.Why is the Interrupt method more efficient?”


3/7

Help stuff you need: for counters refer to book digital design by morris mano or digital circuits by

anand kumar.

For mcu you can refer for microcontrollers by mazidi .

Do google search you will find a lot about these.

Note:

if you do not have the proteus software or if you any other problem , you can contactundersigned.

Mention the Subject Line as “ Embedded System second year “ in your mail.

Control System

Second Years: Deadline : 10 Sept. 2015. Study the basics about signals. You should have some knowledge about Causality, Stability, Linearity, TimeInvariance. Also study about Fourier and Laplace Transform. Their properties and applications.

Study about accelerometers , gyroscope and magnetometer and about PID algorithms.

Task:

Two DC motors with the same technical specifications would never run at the same speed. When thesemotors are used to make a robot, it will never go in straight line.So to make it go in straight line you need towrite a code (in Arduino) which makes use of PID .You can use any other electronics components you wantto use.

You have to send us the code and its documentation.

Image Processing and Software Development

OpenCV (Open Source Computer Vision) is a C++ library of programming functions mainlyaimed at real-time computer vision, originally developed by Intel research center.

For second years students Deadline : 10th September 2015 (Thursday)

Task:

1. Go through the document regarding OpenCV tutorials.

2. Integrate OpenCV with any IDE in your system preferably, LINUX(Ubuntu). Windows will

also be fine.

3. Implement the attached research paper using OpenCV.(ImgProc Module) 4. Send an attached report specifying the steps undertaken to perform the task along with the

code and results of the execution.

Resources:

1. OpenCV Tutorial : https://goo.gl/u6YKvp

2. Steps to integrate OpenCV onto an IDE can be found simply by searching on Google. Anyerror encountered during integration process can be solved by simply searching for the error on

the internet.

3. Reseach Paper : Real Time Visual Saliency By Division Of Gaussians :

https://goo.gl/VbC2SL

4. Do not get overwhelmed by the term Research paper. The ImgProc section of the OpenCVtutorial documents contains all the relevant functions required to implement the paper. For

everything else, there is Google.

Note:Mention the Subject Line as “ Image Processing second year “ in your mail.

MECHANICAL AND FABRICATION DEPT.

Instructions

1. All the candidates will have to maintain a register in which they will have to record briefly, important pointsrelevant to tasks given below. They have to come to AUV LAB on date of their respective deadline forevaluation (timings will be updated on DTU AUV facebook page). Failing to do so will result in elimination.2. Second Year students have two chose from two departments, one is design and other is manufacturing andhave to do the task accordingly.

Second years Deadline 9th sept (wed) Design group

1. Study the water sealing technique in AUV using the concept of face seal and gland seal. Design andunderstand various parameters involved in choosing the appropriate O-ring for both the cases. 2. Design coca cola bottle/cup/rocking chair or any other real object you encounter daily on solidworks/nx/creo.

Manufacturing group

Task : study of various machining processes namely, milling, lathe ,grinding and tools associated with it.Suggest the appropriate method of fabrication of different parts of AUV eg. Lids, frame, camera pods etc withreasoning.

Resources :1. ROV manual : https://goo.gl/DBGWDc

2. Stability videos : https://goo.gl/xbRSbM

3. AUV journal paper : https://goo.gl/ebPnUm

4. O-ring handbook : https://goo.gl/AyZEbJ

5. For solidworks there are many tutorials on youtube to get started or for advanced designing.

6. There are no specific links for fabrication part. You can search on google to get information from

multiple sources. Youtube videos might be helpful to understand concepts better.

b) Try to develop a NEW algorithm to localize sound source using 4 hydrophones in3D. If possible write it’s code in MATLAB and cross check your algorithm.

c) While using TDOA method to localize source,check whether there is any restriction inpositioning of hydrophones, give reasons for it.

3) There is a pinger (sound source) of radius R emitting a broadband signal with frequency rangeof F1R).Inter hydrophone distance is D.Take speed of sound to be c.

The angle between the wavefront plane and the perpendicular to the line joining is ɸ.If the wavefronts hits hydrophones at time t1 and t2.
