Electronic-Mechanic, regular, first year, project-based learning 

Today the concept of robots is seen as a way to reduce human effort and increase productivity without compromising on quality and accuracy of the work. This project considers the implementation of a robot, which can be operated wirelessly using Bluetooth technology. Integrating hardware and software is the key for this project. By integrating hardware and software, the students found just how much technology can be used to develop an outstanding project. The group went a step further by creating an even safer version of the mower. In addition, the autonomous version is also much more convenient for the user. The project includes a heavy amount of circuitry, programming, and integration of the two. The project was done in two different stages. The first stage the group completed was the android application for the wireless control of the lawn mower. The second stage of their project was creating an Autonomous Lawn Mower. This report describes different aspects (technical and non-technical) of the lawnmower.

Dustbins (or Garbage bins, Trash cans, whatever the term used) are small plastic (or metal) containers that are used to store trash (or waste) on a temporary basis. They are often used in homes, offices, streets, parks, etc. to collect waste. In some places, littering is a serious offense and hence public waste containers are the only way to dispose of small waste. Usually, it is a common practice to use separate bins for collecting wet or dry, recyclable or non-recyclable waste. In this project, we have designed a simple system called Smart Dustbin using Arduino, Ultrasonic Sensor and Servo Motor, where the lid of the dustbin will automatically open itself upon detection of human hand.

Concept behind Smart Dustbin using Arduino: The main concept behind the Smart Dustbin using Arduino project is Object Detection. We have already used Ultrasonic Sensor in Object Avoiding Robot, where upon detecting an object, the Robot will change its course of direction.

Fitter regular and dual students have done “Die Table” as a project. We have designed a new steel base table with a 25-30 cm larger glass table top named “Die Table”.

“Die Table” has six sides, which are equal in dimension. Each and every side can be used as top or bottom. It is compatible and portable. It is made with accurate angle cutting, fine welding and with perfect finishing. A two-dimensional MS tube with 11 and 15 inch is used for making it. The various applications of this table can be used in living room, reception hall and office.

The trainees are trained in such a way that they have very good skills in designing, perfect sawing, accurate welding, grinding and fine finishing.

The solar lamp is made by the students and teachers of Fitter, Electronic Mechanic and Electrician courses. The lamp has a small solar panel, a charging module, batteries and a bulb. Such a lamp can be used either as a reading lamp in a house or in a garden.

The students of Fitter under the guidance of our teacher Kesavan made the metal part of the project.The students of Electronic Mechanic under the guidance of our teacher S. Manikandan made the charging part and the students of Electrician under the guidance of our teacher Shiva Kumar did the electrical part of the project.

Technical data of the project: 3W Solar panel, 6V battery, 3V LED.The stand and the bottom are made by using aluminium rod, solar panel, charging board, Led, connecting wires, batteries and shade. In this project the Fitter trainees learned to use lathe and milling machine whereas the trainees of Electronic Mechanic course learned to make a charging panel and about the concept of using solar energy for lighting. All trainees learn the process of making a solar lamp from design to finish product. Costs of the project: Rs. 1200. This project won 2nd prize at the exhibition organized by the Government of Pondicherry in 2018.

For the affiliation to NCVT course in Hardware & Networking 6 Hardware and Networking trainer kits are prescribed by NCVT for PC Hardware testing, Network testing and DC voltage checking and to identify the error component. In the market each of such kit cost approx. Rs.1 lakh.

AIAT teachers S. Manikandan (Electronic Mechanic), Ravi Shankar (Hardware & Networking) and Mahendrian (Fitter & Welder) found it to expensive and made a proposal to make such a trainer kit in the institute as a part of the project-based learning. In a team they designed the kit as per specification and made it a teamwork together with the students of Electronic Mechanic, Hardware and Fitter & Welder. Technical specification: Size: 6 x 4 Ft. Costs of the project: Rs 6000 in addition to an old computer.

This project was shown at the exhibition organized by the Government of Pondicherry in 2018.

For our students of Fitter and Welder trades AIAT is in need of 60 toolboxes. The students of Fitter and Welder trades should receive a set of tools in a toolbox for their project work at the institute. For that a toolbox project was initiated. The toolboxes of the size 50x20x22 are made of galvanized sheets. The students of 2nd year regular and Dual Fitter course are making it in a serial production. The welder instructor Ravi K guides them and had made various prototypes before going for final production in a larger scale. On this project trainees are learning skills on sheet metal. This part of training is beyond the syllabus for Fitter course. Grace Infrastructure funds this project. The material cost of such a box is approx. Rs.550/box.

Generally Shiva Lingam is a symbol of Lord Shiva (symbol of energy, and infinity).

It is a project of Fitter 2nd year class of batch 2017-2018. It is made of Aluminium or Steel rod. The 2nd year students made it as part of training in turning. 

Dimension: 70 mm height x 40 mm diameter.

This project is an up cycling project. It is made of MS-pipe waste. In 2018 students of the welding course made this table and 4 chairs by using ½ inch diameter pipe scrap of 6 inches length. The glass plate, wood and leg bushes were bought. It is a project of welding faculty. Students of welding course under TNSDC were practicing welding, grinding and painting skills in this course. 

Instructor: K. Ravi.

Made in the electronic mechanical class of the Institute of Applied Technology, Irumbai/Tamil Nadu, South India. (Video Tamil Version)

Corona Pandemic has paralyzed the life of Mio. of Indians. India has imposed longest and strictest lockdown in the history to stop spreading of the virus. One of the measures to stop spreading is frequent disinfection of hand. AIAT Electronic teachers came up with a project Idea of “Hand Sanitizer”. On 16th March 2020 AIAT made a demonstration of feasibility to the honourable MP of Villupuram Mr. Ravi Kumar at his surprise visit to AIAT.

But to make it a product for daily use we need to have a look at market segment, design, cost, quality, service and distribution.

Just after the total lock down in May 2020 a team of teachers from Electronic Mechanic and Mechanical faculties started working on a design, specification and on a prototype for a “Hand Sanitizer”. 

The final product “AIAT Hand Sanitizer” is now ready. 5 pieces are made by the students & teachers of Electronic Mechanic and Fitter & Welder. 2 pieces are installed at AIAT itself, one at the factory of Le Bracs in Pondicherry-Sedrapet and 2 are planned to be installed, one in Auroville and another in Pondicherry. It can be filled either with any alcohol-based disinfection agents. The Hand sanitizer has a capacity of 2 litre. It is optical sensor based and has a steel body. Its capacity is large enough for disinfection of approx. 200-300 students daily.

Benefit of AIAT hand sanitizers:

• It is a fully automatic sensor-based sanitizer. No risk of infection at sanitizer machine!
• It has a robust steel body, best for school environment. 
• Its storage capacity is 2 litters, large enough for 200 to 300 people / day.
• It is easy to refill and maintain, thus running cost is low.
• AIAT delivers after sale service!
• How can you acquire this AIAT Hand sanitizer?

The aim of this project is to develop an automated plant watering System that waters the plant every time the soil gets too dry. This project was realized as cooperative work of 1st and 2nd year dual system students, their teachers Manikandan, Mohammad and our Austrian Volunteer Clemens.

The base is a moisture sensor, which is put into the soil next to any given plant. The whole project cost amounts to around 2000 Rs and took about 1 month to complete, because there was a lot of theory and testing that needed to be done.

This project gave the students an introduction to Arduino, moisture sensor and how to use them. Also, could the students gain some insight on how to use pump-controlled water systems.
