Window Glass Cleaning Robot

Description: This particular robot requires the adhesion of the 3M cleaning pad material with the glass and hence, a vacuum needs to be created which will stick the suction cup to the glass surface. The vacuum can be actuated mechanically as seen in the video in the side panel. The suction cup can be used on vertical surfaces and can clean glass buildings so that the people who operate under such risky conditions can avoid such situations. Mechanical actuation of this suction cup can be achieved using a motor controlled by an Arduino

Mechatronics design of spray mechanism for floculation of muddy water from potholes

Description : The project successfully demonstrates the spray mechanism for dispensing of a floculating chemical which is a anionic polyelectrolyte FLOCSURE-4X-E supplied by Sriram Chemicals for effective flocculation of muddy water.The muddy water in potholes, roadside trenches or pavements can be very well cleaned by this method and further re-used for domestic purposes like flushing of toilets, cleaning of utensils and for bathing purpose with minor water treatment methods. Roadside vendors can very well use this water for their businesses.

Ozonisation of pothole and sewage water in Mumbai

Similar treatment was carried out on sewage or greyish water collected from road-side gutter. The water was treated using Ozone supplied by AMOZONICS. The treatment of muddy water was achieved using 50 ppm of Ozone while that of greyish water was achieved using 80-100 ppm of Ozone and has been carried out in collaboration by AMOZONICS

*The water samples collected have not been tested for presence of viruses and bacteria including the coronavirus SARS-COV2
Faculty : Mina Bairagi (mina.bairagi@gmail.com)

Salient features:

The dispensing mechanism works on a simple rack and pinion principle which is actuated by a DC motor.
A spray bottle is actuated and a volume of 30 micro-ml can be dispensed during one cycle of operation.

Application in Automotive industry

This mechanism can be used in combustion process for the IC engine and further design of next generation injector nozzles based on these experiments can be very well carried out.
Performance characteristics related to nozzle parameters and combustion efficiency can be studied as part of future work in the automobile industry.
Image processing based research can be carried out related to estimation of flocculation efficiency
Flocculation efficiency studies for various chemicals to be carried out in the future

Fuel estimation based on real-time accelerometer data gathered from ADXL345 or a Smartphone

Description : The project aims to demonstrates the accurate estimation of fuel consumed by a IC/Diesel engine vehicle based on real-time acceleration data gathered from a smartphone or a ADXL345 sensor attached to the dashboard of the vehicle. Accurate fuel estimation is required as vehicle dynamics, acceleration and braking pattern, road conditions, idling etc play a very crucial role in fuel consumption and affect the instantaneous fuel economy

Collaborative researchersAli Hussain Ansari , Sales Executive, Hyundai (ansarialihussain78@gmail.com)

Salient features:

The algorithm simply computes the fuel consumed proportional to the instantaneous acceleration in the driving direction
The kFE (fuel estimation constant) for every vehicle can be determined based on historical acceleration data gathered from Sensor Record. This app needs to be downloaded from Playstore and the acceleration data needs to be saved in Excel in raw format for further analysis.
The algorithm will be converted into an app to be displayed in real-time to the driver while driving on the road and can be used in maps to determine routes where optimal acceleration is possible to minimize fuel consumption.

Automatic Plant Irrigation System using GSM enabled Arduino

Description : The video explains the system built using Arduino micro-controller which is able to sense the moisture level in the soil and accordingly dispense the required amount of water through a submersible pump placed in a tank. The moisture level whether LOW, MEDIUM or HIGH can be displayed as a message on the smartphone and accordingly the action is taken and required amount of water is dispensed.

The SWM-500 add on filter has been fabricated in-house. Companies interested can deploy a team to implement the same and can reach the concerned person at amolmk@eng.rizvi.edu.in or 91-8007977166
The SWM-500 add on (with Velcro and activated charcoal dust) will reduce the effect of pollutants that are inhaled by the person and hence will lead to prevention in respiratory illnesses which occur due to prolonged exposure. Activated Charcoal Dust (ACD) enclosed within the SWM-500 double layer will filter the air particles.

Design and prototyping of a Anti-COVID device primarily for common man, medical doctors and front liners

The image shows a proposed design of an Anti-COVID device which snugly fits into the nose of a human being. The function of this device is the gas exchange through photosynthesis of a leaf of the orange plant which has a stomatal pore size of 0.1 micron. The stomata allow for air into the leaf and in the nasal cavity but as the size of the novel Coronavirus is 0.05-0.25 micron, it effectively eliminates the entry of the virus into the nasal cavity. This particular leaf is put inside a anti-snoring device which is approved for usage by medical authorities. The leaf needs to be replaced every 2 hours and fresh leaf needs to be placed in its place. The photosynthesis process will aid the respiration.
This device will aid a lot to help front-liners and medical professionals who continuously interact with COVID-19 patients and improve their resistance to the virus. It will also allow effective blockage to aerosol particles during pregnancy operations of COVID-19 mothers and benefit the medical community as a whole. In-order to allow for better breathing and air inspiration, an air pump connected to the breathing pattern of the person can be designed. Normal people who can afford cloth masks may also find this add-on device very beneficial.
Recommended usageThe anti-snoring device has been procured from the following link. This device is BPA and FDA approved and hence does not require medical certification. The device has the flexibility of opening and insertion of the citrus leaf for reduction of possibility of entry of the novel SARS-CoV2
Disclaimer : The proposed design is use at your own risk. The author cannot be held responsible for any health benefits or damages due to the usage of the device. The author in his capacity does recommend this device for usage of front-liners and also for companies to take this further for trials to bring it into the market for usage of common man.
Stay at home, save lives and lets together fight COVID-19 !

Advantages1) Typically masks result in re-circulation of carbon dioxide and also lead to suffocation.2) Face shields cause hindrance in getting into close proximity for doctors to conduct operations.3) The above device with the citrus leaf can be made to secure your nose and allow the mask to cover your mouth thus allowing for access to fresh air and normal breathing to occur with the environment.
Disadvantages1) Photosynthesis studies for life estimation of plucked leaves yet to be carried out.2) Certification by medical authorities needed.

SWM-500 Add On Filter design for COVID-19

The video in the side panel shows the fabrication of a add-on to the normal cloth or 3-ply mask. The add-on consists of a SS304 Mesh 500 (with pore size of 37 microns) and is sealed with Activated Charcoal Dust. The add-on will act as a filter against pollution and also improve the air quality. The add-on can be just clipped to the cloth mask as seen in the video. The project report related to the fabrication of the SWM-500 add on mask can be accessed here.
*The adhesive used for making the pouch is SPEB7 which needs to be replaced by a suitable metal-metal adhesive or the edges of the SS-MESH filter need to be fused either by melting or welding the same to each other.
The suitable adhesive suggested for this filter is LOCTITE 415 which is available at the following linkWith minimal human requirement, the above task can be fulfilled and the desired filter can be achieved.
