E-Care 2015

Written by Sahani Goonetilleke.


The E-Club, once again, partook on the worthy cause of holding its annual CSR project, "E-Care 2015" at a rural, underprivileged school; namely Paragala Kanishta Vidyalaya, Deniyaya. The charity program was conducted over the weekend, on the 7th and 8th of November. In-kind and monetary donations were collected from well-wishes.
The proceedings commenced after a warm welcome from both staff and students of the school. Then the participants enthusiastically got down to work.

Some of the contributions included:

  • Refurbishing and building a ceiling for the school's laboratory and staff room
  • Workshops for students, on Ordinary Level Mathematics and Science, including practicals
  • English and Music classes
  • Painting the Premises
  • Setting up a library comprising of textbooks, O/Level past paper books and dictionaries
  • Outdoor games and activities

The donations included:

  • Laboratory Equipment for O/Level Science practicals
  • Musical instruments to initiate Eastern Music as a subject in the school for the O/Level examination.
  • Speakers and amplifiers to conduct morning assembly.
  • Stationery items

It is indeed heart-warming to know that the lives of 120 children were transformed for the best; while providing a better learning environment and opportunities to nurture their talents. We extend our sincere gratitude to each and every individual who contributed to make this event a reality.

FPGA workshop by ParaQum Technologies - Semester 4

Written by Sahani Goonetilleke.

ParaQum Technologies, a start-up company driving their way to the world of High Speed Digital Design and FPGA, conducted a special workshop for the semester 4 ENTC '13 students. The focus area of the workshop was "Digital Design using FPGA" and it was conducted by Mr. Kalana De Silva and Mr. Geethan Karunarathne. The workshop was held on the 1st of November 2015 at ENTC 1, ENTC. An extensive coverage of the following were completed in a relatively short time duration:

  • Overview and architecture of FPGA
  • Simulation and Implementation flows
  • An introduction to Verilog coding
  • Digital systems design using Verilog HDL

Aspects of combinational and sequential logic and examples on both hardware and software applications were interactively discussed. This workshop was beneficial for the students as areas of subjects of future semesters such as DSD and IC design, were also covered.

“Catch Me If You Can” Robot Design and Competition – ENTC ’13

Written by Sahani Goonetilleke.


Designing and building a robot performing dual tasks of either catching or evading an opponent’s robot within a circular arena, was the challenge given for the semester 3 EN2532 module, Robot Design & Competition. The students rose up to this comparatively tedious challenge while developing ones knowledge base and skill set in an enjoyable manner.

An overhead camera was used to determine the positions and velocities of each of the robots, and the data was transmitted to the two teams in real time at a predetermined rate. A round commenced when a START command was received by both robots simultaneously; and ended when the chaser bot touched the evading bot or when a bot goes beyond the boundary or ultimately after a time lapse of 100 seconds. Then the STOP command was sent to both bots. Two cylindrical obstacles were also placed at random positions and the robots had to undergo their task avoiding collision with the obstacles or incur a penalty. Points were calculated considering the mean distance maintained with an additional time-based bonus.

The initial evaluation in which each group delivered a presentation showcasing their preliminary design and strategy, was conducted in June. Mid evaluations were held in late July, where each group demonstrated a working robot platform that can navigate in the arena. Prof. Rohan Munasinghe gave his valuable advice and insight on each robot in discussions with each group.

Days of hard work and sleepless nights finally culminated with the evening of the Robot Competition on the 12th of October 2015. Amidst a wide variety of spectators from various departments, the competition kicked off with much enthusiasm. The judging panel was headed by Mr Buddhima Gamlath. For the group stage, 20 teams of 5 members each, were divided into 5 groups, named group A to E consisting of 4 teams per group. Each team competed against all the other teams in the same group. At this stage a total of 30 matches were contested with each team playing 3 matches. The leaders of the 5 groups proceeded to the next round. Since the leading teams of groups B, C and E were unbeaten, having won all 3 games; they automatically advanced to the semi-finals. To determine the remaining slot of the semi-finals, the leaders of groups A, team 6, and of group D, team 17 duelled a knockout match, in which team 6 prevailed. In the 1st semi-finals match between teams 4 and 5, Team 5 emerged victorious while in the 2nd semi-finals between teams 6 and 15, team 15 triumphed. Finally team 15 emerged champions with an unbroken winning streak, while team 5 was runners up.

ENTC develops an ATS for SLAF

Written by Madara Wimalarathna.

The department of Electronic and telecommunication Engineering of University of Moratuwa (ENTC) has been working with SLAF (Sri Lankan Air Force) for some time and recently ENTC was requested by SLAF for an ATS (Antenna Tracking System) for UAVs (Unmanned Aerial Vehicle).mini-uav-fixed-wing-civilian-100901-2965447 1

Main requirements of the ATS are the antenna should identify where the UAV is and turn towards it automatically. So there are two degrees of freedom, azimuth and elevation. It takes the GPS position and elevation of the UAV. Since it has the GPS position where the ATS is, it calculates the angle to turn in order to track the UAV.

ATS design and development team has visited the Katukurunda Air Force base and ready to start the development process within next couple of weeks.  Prof. Rohan Munasinghe head of the department of Electronic and telecommunication Engineering confidently says that this project will be completed successfully with a perfect output and it will strengthen the relationship between ENTC and SLAF.

ENTC UAVs for Disaster Management

Written by Hiranya Kuruppu.

Over a span of many years, the department of ENTC has been working on projects in collaboration with various organizations. One such project was recently undertaken at the request of UNDP (United Nations Development Project) through the COSTI (Coordination Secretariat for Science, Technology and Innovation). The letter of agreement has already been signed between the University Of Moratuwa and the UNDP, to develop a UAV for disaster management, which should be small in size and conveniently movable. Furthermore the capability to send a 3D map of the affected ground area within a half an hour to a server, in order to alert the rescue teams immediately, is the prime requirement of the UAV.

Necessary assistance would be provided by the DMC (Disaster Management Center) and other government organizations to the project worth 20,000 USD, sponsored by UNDP. The project is to be commenced after the approval of the council on 7th October.
