Make In India

IIT Bombay at the Make in India (MII) Week

 

The Make in India Week, organised by government of India from 13th to 18th February, marked a milestone in the overall roadmap of the Make in India initiative. It was a flagship event aimed at propelling the Indian economy by forging enormous global engagement with Indian industry in the form of partnerships and investments. The event spanned several states, and the response was phenomenal. IIT Bombay was intrinsically involved with the proceedings, hosted a Hackathon, as well as set up the IIT Pavilion. The most relevant and pertinent issues facing India were brought up, discussed and dissected at the Industry Academia Symposia, which was also organised by IIT Bombay. Professor Devang Khakhar, Director, was one of the speakers at the symposium along with other luminaries from various fields.

The Hackathon 

The Hackathon brought together engineers, designers and coders so that they could focus on innovating and solving problems that matter. After evaluating a plethora of issues that are facing India today, the panel which consisted of professors from IIT Bombay as well as senior officials from the Department of Industrial Policy and Promotion (DIPP), India narrowed down on three main areas which presents the most formidable challenges for contemporary India. The topics selected for the Hackathon were water, transportation and energy. Student teams were invited to participate in the Hackathon from engineering colleges around the country. A rigorous selection process was used to shortlist the student teams with highest potential. These students were hosted and accommodated within the IITB Campus during the Hackathon, which took place during the week preceding the MII week. The students were given access to various Institute facilities such as workshops and labs for implementing their work and creating their models. They were also assigned work spaces in Seminar rooms and foyer area at VMCC. 

With a diverse population that is three times the population of the United States, but one third the physical size, it comes as no surprise that ensuring clean water to the people would be a priority for the incumbents. This problem has started to rear its head, especially along the rural belts of India. Although India has made improvements over the past decades to both the availability and quality of municipal drinking water systems, its large population has stressed planned water resources. Rapid growth in India's urban areas has stretched government solutions, which have been compromised by over-privatization while the rural regions have been ignored. Around 21% of the company’s diseases are water related, while traditional methods of obtaining water such as drilling wells have contributed to other problems such as erosion and ground water depletion. In such a situation, searching for innovations and alternatives that can provide an alternate solution to this impending water crisis are the need of the hour.

India had always lagged behind in terms of modern means of transportation, and this, was one of the focus areas of the Hackathon. There have been no initiatives for fleet modernisation or infrastructure development during much of India’s history, with legislations concerning emission norms coming as late as 1991. Till now much of the initiatives regarding transportation and infrastructure augmentation have been favoured by the government through subsidies, but to build a formidable long lasting model for the same, one cannot rely on subsidies in the long term. The government has to take proactive steps to empower creativity and innovation in this field, so that one can make sustainable mobility more affordable. The Hackathon provided opportunity to identify projects and ideas for the same so that the green transportation options can be within the reach of any consumers

In the context of India’s economic development energy crisis can take many forms. There is recurrent oil shortage, with India’s reserve being 0.3% of the world’s known oil reserves. The coal that is mined in India, fails to meet the standards, both quantitatively and qualitatively. The power generated is also severely limited in terms of generation and distribution. Energy shortage in turn has an adverse effect on both the agricultural and industrial output. In light of all these facts, the final theme was energy.

Proposals were set in by 150+ teams elaborating their ideas to solve problems in the three themes of the MII Hackathon. A team of faculty across the IITs went through each of these proposals and short-listed 30 teams that would be invited to IIT-B for the MII Hackathon. The proposals were evaluated on the basis of the following criteria:

  1. Strength of team
  2. Potential Impact
  3. Novelty of the idea
  4. Understanding of technology required to realise the solution
  5. How realistic are the components/subsystem requirements?
  6. Robustness of the solution
  7. Viability
  8. Do the use cases cover the defined problem?
  9. Design
  10. Judges Discretion

The MII Hackathon team then put together details on the specific requirements of each of the teams including hardware, software requirements, mentoring requirements, physical space and lab requirements for them to implement their ideas at the Hackathon.

The participants were accommodated within the IIT-B hostels for a more immersive experience. The students were given access to the labs and workshop facilities available in IIT. The final ideas were developed by the students in collaboration with the IIT Bombay faculty and research scholars. Once they reached the campus, they had the paraphernalia of IIT Bombay at their disposal. Lots of workshops and talks were conducted across the week on all of the three topics chosen.

 

Mentor Team Interaction Sessions

The teams were organized into three groups based on the theme (Energy, Transportation or Water) for which they had submitted their proposals.  There were 10 short-listed teams in each of three themes. Each of these teams were assigned a student mentor, typically a doctoral student. A team of 10 design mentors were also available during the pre-Hackathon workshop and interaction sessions to assist with design and product showcase inputs.  The mentors were assigned to the teams by the faculty based on the mentor requirements specified by the teams at the time of collating the implementation requirements. For the first three days of this week-long event, i.e on 10-12th February, post lunch sessions were assigned for exclusive mentor-student interactions. This gave the teams an opportunity to improve their prototype with inputs from doctoral students of the Institute. The students also interacted with faculty for specific inputs on their ideas during these sessions.

 

Workshops and Tutorials

Some interesting workshops were also conducted as part of the pre-Hackathon sessions. The workshops included hands-on sessions on using embedded systems hardware such Arduino boards, Beagle Bone, interfacing different sensors with these boards and general usage of electronic components, Real Time Operating Systems, Android App development and building a MVP (Minimum Viable Plan) for those planning to pitch to investors. The participants were also taken on a tour of other facilities within IIT Bombay that are addressing Energy related problems - such as the National Centre for Photovoltaic Research and Education (NCPRE) and the Smart Energy Informatics Lab (SEIL).

In the water category, Vivekanand College of Engineering, Mumbai won the first spot. They proposed a low-cost irrigation set for farmers affected by drought in the country. Harsh Gupta and Nirbhay Pherwani made a subsurface irrigation model which has a sensor-based crop prediction system. The sensors detect salinity, water content, etc., and provide data on these parameters to help predict crop growth, survival chances, yield, etc. The information collected by this system is periodically sent to the farmers through text messages. This will enable the farmers to change their methods accordingly. After winning the award, Harsh and Nirbhay got two proposals to collaborate with agriculturalists. They now plan to establish a start-up. The National Law University, Assam and Jodhpur Institute of Engineering and Technology shared the second position. 

In the energy category, IIT Kanpur held the top spot while Vellore Institute of Technology, Chennai campus and Karpagam College of Engineering, Coimbatore shared the honours for the second spot. 

In the transportation segment, Krishna Institute of Engineering and Technology, Ghaziabad came first followed by Centre for Environmental Planning & Technology, Ahmedabad. 

"India cannot be a great manufacturing nation until we invent, innovate and design in India . Our belief is that we had lost our close relationship between academia and industry. Our IIT and engineering institutes will play an important role to take it forward," said Amitabh Kant, secretary, Department of Industrial Promotion and Policy (DIPP).

Machining of Advanced Components

Blisk Machining

Blisks are axial flow compressors that are found in aircraft engines and gas turbine power plants. The design of blisks feature complex free-form surfaces in the form of twisted airfoil shapes, and they must be manufactured accurately for optimized performance. Blisks are usually made of Titanium and Steel alloys which are difficult-to-cut materials, and this makes manufacturing very challenging. The process time for the blisk is about 30 hours, and approximately 50 percent of the workpiece material is removed to get the final part. The part has been machined on a 5-axis machining center using 3 cutting tools for different stages of the process, and the surface finish is approximately 50 microns.

Impeller Machining Impellers are essentially centrifugal compressors that are used in helicopter turbo-shaft engines, and in airplane Auxiliary Power Units (APU). They have intricate designs so as to maximize operational efficiency. They are also required to withstand thermomechanical stresses during operation. Impellers are usually made of Titanium and Steel alloys which are difficult-to-cut materials, and this makes manufacturing a great challenge. The process time for this exhibit (made of aluminum) is about 48 hours, and approximately 60 percent of the workpiece material is removed to get the final part. The part has been machined on a 5- axis machining center using 3 cutting tools for different stages of the process, and the surface finish is approximately 4 microns.

Turbine Blade Machining Turbine blades are found in the hot-section of aircraft engines and gas-turbine power plants. They transmit power to the fan and compressor section of engines, and to the generator when used in power-plants. The blade profiles are aerodynamically designed to improve performance. They are required to withstand extremely high temperatures and pressures, and they must not deform under thermo-mechanical loadings. Made from Nickel based heat-resistant super alloys such as Inconel, the blades are extremely difficult to machine. Given the complexity of the part geometry and workpiece material characteristics, the process requires extensive modeling, optimization and validation. The process time for this exhibit (made of aluminum) is about 36 hours, and approximately 80 percent of the workpiece material has been cut to get the final part. Due to the slender design, there are lot of vibrations in the tip region of the part which must be accounted for in the process plan. The part has been machined on a 5-axis machining center using 3 cutting tools for different stages of the process, and the surface finish is approximately 7.5 microns.

TMT Diaphragm Machining TMT (Thirty Meter Telescope) is one of the world’s largest ground based telescope project. The central diaphragm is a critical component which is used to support the mirror segment in each of the 492 Primary Segment Assemblies that make up the telescope’s complete primary mirror. The diaphragm is made of INVAR-36 which is an alloy of Nickel and Iron, and is a difficult-to-cut material. Machining this material leads to part distortions as a result of induced residual stresses. Furthermore, the part has extremely narrow tolerances of the order of 50 microns. NCAIR is involved in the process design and validation for accurate and efficient manufacturing of the diaphragm without distortions and stresses.

Avionics Mounting Tray

Carbon Fibre Reinforced Polymer (CFRP) Line-Replaceable Unit (LRU) Tray The avionics mounting tray is a flat frame which houses avionics system components of military and commercial aircraft. It is designed to withstand shock loads that are encountered during flight as per established military and civil aircraft design standards. The improved design now features carbon fiber polymer composite material which is significantly lighter than Aluminium that was used previously. The new design is capable of withstanding two times the designed loads, and the shock load limit has been increased from 30g to 40g for 11 milliseconds. The part can also withstand gun fire vibrations with 17g to 32g vibration levels. The overall weight has been reduced from approximately 1 kg to 450 grams.

Knee Implant

Legs of children affected by bone cancer can be saved by reconstructing their knee joint after tumor removal. A novel rotating-hinge modular knee mega-prosthesis was developed at IIT Bombay in collaboration with Dr. Manish Agarwal (Hinduja Hospital) and NFTDC Hyderabad, supported by the Office of the PSA, New Delhi. The prosthesis is designed for Indian anatomy, and has quality and reliability comparable to imported joints, but costs less than half. Novel surgical instruments and software have also been developed. Several hospitals have come forward for clinical trials. Several expert surgeons, institutes and industry are working with IITB for indigenous medical device innovation.

OmniCant

Functionalized, Multi-channel MEMS Cantilever based Experimentation and Research Platform for Vapour Phase Analysis of Volatile Organic Compouds and Gases. OmniCant is a table-top platform that enables researchers to perform chemical/gas sensing experiments with MEMS Cantilevers. The major components are the analyte chamber (which stores the target solution), reaction chamber (which houses the cantilever sensor) and integrated mass flow controllers and valves (that enable & control flow of analyte to reaction chamber). The target vapours are heated and carried to the reaction chamber where they interact with the cantilever sensor. This interaction is measured as a function of change in resistance of the cantilever (easy electrical readout; no bulky optical setup required). Variables: Flow rates of analyte and carrier gas, Temperature of analyte and reaction chamber, surface coating on the cantilever and analyte compound. Applications: Gas/Chemical/Biochemical Sensing

Solar Lamp

Million SoUL Program As per Census 2011, there are 7.8 crore households & about 350 million people in rural India who still use kerosene for lighting purposes. Many young children going to schools either do not have access to alternative light sources or suffer from erratic supply of electricity, thus hampering their studies. Considering this, IIT Bombay has undertaken an initiative to provide light to every child through the Million Solar Urja Lamp (SoUL) Program. The main strength of the program is the localization of solar energy in which assembly, distribution and repair and maintenance of solar lamps are done by the villagers themselves. More than 1000 rural people in partnership with NGOs were trained to perform these activities; 60 local assembly and distribution centres and 350 local service repair centres were established. The program includes the states of Madhya Pradesh, Rajasthan, Maharashtra and Orissa covering 97 blocks of 23 districts and 10,000+ villages, with more than 9,20,000 student beneficiaries (as of February 2016).

Electronic Voting Machine

IDC, IIT Bombay was approached by BEL for designing the voting machine in the year 1989 after the constitutional amendment was passed to enable use of such machines. The design team led by Prof. A. G. Rao and Prof. U. A. Athavankar visited the sites and did an in-depth study of the users as well as the officials and the processes used in elections. Several concepts were presented and finally this simple elegant product was created, which is so state of the art and contemporary that it is still in use after 27 years. The product's form gives the assurance of being tamper proof and is compatible with other electronic products in looks and accessibility.

Rupee Symbol for India

The Indian rupee symbol designed by Dr. Udaya Kumar, who was the first PhD student of IDC. The design of this symbol was selected through a nationwide competition. The design integrates both the Devanagiri letterform 'RA' and the Latin capital letter 'R'. The Unicode character set for the Indian rupee symbol is U+20B9. The design philosophy of the symbol is derived from the Devanagari script, a traditional script deeply rooted in our Indian culture. The symbol also seamlessly integrates the Latin script which is widely used around the world.

Heat Pump

Heat Pump Laboratory at IIT Bombay in the Mechanical Engineering Department has been working on Energy Efficient Technologies It has filed 27 Indian Patents 27 (14 Granted + 1 defended/awaiting grant + 12 being examined) Over 14 Technologies have been Developed, Transferred, Licensed and Commercialized Exhaust Heat Recovery Units, Multi-Utility Heat Pumps, Super Heat Recovery Water Heaters Many more are in the process of being transferred Solar Air Heaters, Solar Steam Generators with Absorber Integrated Storage, Solar Steam Cookers, Solar Dryers, Energy Efficient Agro Produce Dryers, Heat Pipe Integrated Low Temperature Dryers, Air to Air Heat Recovery, Indirect Evaporative Coolers

Dental Crowns

Materials for ceramic dental crowns fabricated by CAD-CAM: Over the years use of Íšall-ceramic dental crowns have gone up significantly owing to their superior aesthetics, high strength leading to higher reliability / lifetime and no adverse reactions with the underlying tissues. Glass infiltrated alumina or zirconia toughened alumnia was used as material for Íšall ceramic dental crowns till recently until newer materials were developed which are easier to fabricate and do not involve manual processing steps which had to be carried out by skilled technicians. The newer materials are expensive and out of reach of the masses needing dental treatments. We have carried out research to develop materials similar to the glass infiltrated ceramics which possess the desired properties needed for making dental crowns and can be processed through CAD-CAM techniques without the need of any manual processing steps. Also, since the ceramic blocks needed for making the dental crowns can be manufactured indigenously the cost is expected to be lower than the other materials. Also, a variant of the material which can be processed through CAD-CAM techniques can be fully sintered dense zirconia toughened alumina which will not need the glass infiltration step.
