TechTatva ’19⁠—Mechanize

CAD IT UP
Aditya Narayan | Staff Writer

The CAD software is undoubtedly one of the most important aspects of engineering a prototype into functional reality. Keeping this in mind, Mechanize hosted its flagship event, CAD IT UP, drawing a good crowd of participants in the pre-TechTatva workshops and according to the event heads, generating an overwhelmingly positive response.

The first round was challenging, but nothing impossible, even for beginners. The questions consisted of drawing out four to five 2D structures in the software. Since the competition was open to every student, first-year participants were to be awarded a bonus of ten points in this round, and five points in the second. “I believe that if someone has a keen mind, and learnt what was taught well, they could quite easily hold their own against someone with more experience. Talent knows no bounds” said Anshuman, the Event Head. The second round was a lot harder than the first since the participants were required to render the given series of 3D models, using the AutoCAD software.

Out of the eight people participating, five qualified, but it was the third round that set the real challenge. The round had three questions—a 3D rendition of a given object, with competitors having to take precise measurements on their own, another 3D model to be drawn, gauged from the given side and top views and the hardest, drawing an assigned structure, from scratch. Only two of the participants chose to compete in this round, while the other three chose to participate elsewhere. The participants were to be judged on their level of detail, the usability of their design, the cost-effectiveness of the materials and structures used, and the feasibility of production. Both of the final competitors, a third-year and a second-year student, gave it their best, but experience tipped the balance as Sujay Bhaumik, a third-year mechanical student emerged victorious. In the end, the event fulfilled its primary purpose of giving its participants the experience of what it was like to be a product designer and helped them learn how to use the CAD software efficiently.


Maglan Regenerative Car

The Maglan Regenerative Car event commenced on 10th October, on the second day of TechTatva. Even though the event was postponed to a day later than when it was scheduled to occur, the organisers looked hopeful they would find some budding automobile enthusiasts among the candidates who took the written test.

Maglan Regenerative Car is a car that works on the core principles of magnetism, and candidates clearing the written round would get the opportunity to build a prototype of this car in the later rounds. Each prototype would be tested by making it travel along a straight line and the car which would cover the maximum distance would emerge as winners.

The written test for the first round tested candidates on their basic physics aptitude from high school, and although some of the candidates from the Chemistry cycle felt they were not well versed with the topics asked, the overall difficulty level was well-balanced. When asked about the turnout as compared to last year’s, one of the event heads, Gaurang Modi replied, “Even though the numbers were not great due to the odd hours of the afternoon, we hope that more candidates join in for the extended round tomorrow.” When questioned about the relevance of Maglan Cars in general, he said, “The prototype the candidates would build is the basic model that many automobile companies like Tesla make use of. If anything, such knowledge would be of great use to someone who is truly interested.” In spite of the difficulties faced, the event left the organisers and participants visibly content.

Mechanize‘s newest tech-savvy addition, Shooter Spider Robot was aimed at testing participants on how they built their own targeting spider contraption. “We can’t say how the turnout will be this time for the event, but we hope it’s a great number“, said Nandini Mohan, one of the members of the core committee.

The turnout was decent, and the people present were eager to know what the event had in store for them. The quiet hall in which the event took place was buzzing with murmurs of discussions and various hand gestures. Even though the written test was filled with very technical questions focused around the principles of the robot to be built, participants managed to wrap up the session quite early. “We expected something a little more handson at the start, so the written round was unexpected. However, the questions weren’t that hard to figure out“, Anuj Deshmukh, a participant of the event. 

The second and final round involved putting practical skills test to the test, as participants were challenged to build a cardboard robot. The robot would be controlled by a battery source and the shooting mechanism was based on the principles of hydraulics. The round had a few hitches, one being the logistics. However, the Mechanize team put in their best efforts to get the event going, and as soon as the materials arrived, the two teams present raced against each other to build the perfect model. While the relatively new concept of the event left some participants befuddled, they all agreed that overall, it was an entertaining competition.


MetalMind

The lathe is popularly known as the mother of all machines. Paying homage to one of the most everlasting pieces of machining technology, Mechanize hosted MetalMind, an event where the contestants had a hands-on experience of using a lathe. Considering the difficulty level, the turnout was excellent as eight teams showed up. To enable first-years to participate, a pre-TechTatva workshop was also held. This event was still in its infancy as it was being held for the first time ever. The two-round event lasted over all the four days, with the first round being held over the first two days of the fest. The participants were tested on various lathe formulae in a one-hour test. Out of the eight, four teams qualified for the next round.

The second round was an eight-hour-long event which left the machine shop buzzing with the clanking of tools for two days. Rated as moderately difficult by the event heads, the aim was to create a prototype of a rocket. Each team was given an engine lathe. The participants were dexterous as they showed off their machining skills. “I got to try new things because of this competition. It was an excellent confidence booster as I got to compete with people who are really good at this” said Rhythm Jaiswal, a second-year MIT student.

Participating in this event would have definitely taught a lot to the contestants. You get to experience working on a lathe. Making the prototype isn’t that hard. It just requires some basic machining operations” said Milind, one of the Event Heads. The final models were judged by the MIT faculty before declaring Parth Gangrade and Abhishek Nain as the winners. Overall, MetalMind left the event heads and participants satisfied, and is one we might see again in the upcoming editions of TechTatva.
