Report on Best Idea Competition – 2019
Event date: 25/09/2019

Best Idea Competition - 2019 for the students of REVA University. A total of 30 Student teams from various schools (C&IT, ECE, MECHANICAL, CIVIL, COMPUTER SCIENCE & APPLICATIONS, MSc (Biotech)) took interest and displayed their thoughts over the span of this event which comprised of 3 rounds. The event was judged by the Faculty members from various Schools.

The Evaluators and the Faculty members commended students for innovative Ideas. They gave inputs to the students that would lead their endeavors to Publications, Copyrights and Patents.

Hon’ble Director, Dr. Sunilkumar S. Manvi Sir interacted with the students, gave the Certificates and the prizes to the triumphant groups and urged them to implement the Ideas for the benefit of the Society. He assured full support to the students from the University.

The winning ideas / students of this competition are:
1st PRIZE:: Automatic Solar powered Lawn Mower / Kiran N, MECHANICAL & Pradeep Shankar V, C&IT
The students proposed an idea of a solar lawn mower that is a fully automated grass cutting robotic vehicle powered by solar energy that also avoids obstacles and is capable of fully automated grass cutting without the need of any human intervention. The system uses 12V batteries to power the vehicle movement motors as well as the grass cutter motor. It uses a solar panel to charge the battery. The grass cutter and Vehicle motors are interfaced to an Arduino Nano that controls the working of all the motors. It is also used to interface an ultrasonic sensor for object detection. The SoC moves the bot in the forward direction in case no obstacle is detected. On obstacle detection; the ultrasonic sensor monitors it and the SoC thus stops the grass cutter motor to avoid any damage to the object/human/animal etc.
 
2nd PRIZE:: Vertical Parking themed Elevator design / Ayan Ahmed Hussain / R18CV033 / CIVIL, 3rd Semester
Problem : “It is impossible to overload the lifts. If we overload them, the doors will not close. We have a time frame to use the lifts to make the students attend the assembly session before the class commences. Lots of students tend to miss it, so we have so we have set a time limit to take the lift.” Since this is a major problem where more than 15 hours (collectively) are wasted every working day, the Solution was proposed using the idea of vertical parking where there is an acute shortage of parking space into two elevator shafts. One goes up, another goes down. The elevator platform stops at every floor having a separate entry for both up and down on the same time. Entry and exit at the topmost and the bottom most floors can be in a single platform.


3rd PRIZE:: AIR PURIFIER / Rinjan Chatterjee, Rahul Kumar Jha / C&IT/ 3rd SEMESTER
The air purifier contains a fan which regulates the air flow. The size and speed of the fan determines the capacity of the air purifier which is determined by unit cmb (cubic meter/hour) which means how much air will flow every hour. This fan will be put in the middle of the system in a custom made plastic container. The activated charcoal sheets will be put in front as well at the back of fan which removes bacteria and pungent smell from the air by absorbing them. The DSM 501 sensor is used to detect the air quality. The designed air purifier is way cheaper and economical compared to other conventional air purifiers.
