TechTatva’18—Mechanize

Recreate Da Vinci
Shreyas Kashyap

Recreate Da Vinci saw an impressive turnout, especially commendable since this was the first time such an event took place during TechTatva. The event was split into two parts, with the first round being a written round to filter out the best from the rest. For the first round, the participants were made to answer some multiple-choice questions. The paper had two sections—one covering aptitude and logical reasoning, and the other part being more technical testing of basic knowledge of mechanical engineering.

The top four teams moved on to the final round wherein they were required to recreate certain vehicles, such as the paddle-boat and the motorcar. The finalists were allotted the prototypes that they had to create based on their first-round scores. The teams were given more than two hours to construct these working models. They were allowed to use the internet for a short period, in the beginning, to figure out how to make the model. The contestants rose to the challenge soon enough, although a few of them did falter along the way. The testing of the working models led to a fair share of laughs, as a few models failed when it came to execution, but everyone was sure left amazed by the results of the rest.

“I am quite pleased with the overall result and believe that the event progressed without any major hiccup”, said Shubham Khetan, who served as the Event Head for this competition. TechTatva’s newest event was a great success as it was conceived keeping the theme, Reminiscing Greatness, in mind and proved to be a crowd-puller.

CAD It Up

CAD It Up by Mechanize was a software-based event involving the creation of 3D models on AutoCAD. This event took place throughout TechTatva in the PG CAD lab in AB1. It had quite a few participants, engrossed in their work as they raced against time to complete their models.

This event, like most others, had two rounds. The first round consisted of recreating models from a printed question paper. The shapes given were complex and required a good understanding of modelling to recreate. The contestants were given around 75 minutes to complete their drafts for six varied and complex design structures. “As it is a software-based event, we made sure to have our tech team on standby. The participants are expected to complete the models as soon as they can to move on to the next round”, said Rashmi Samant, one of the Event Heads.

The second round consisted of observing a real-life object and recreating it in CAD. The participants were given daily objects such as screws, hangers, and chairs to draft virtually. “They have been given a choice to make the chair however they see fit. It has to be a simple design but should have a lot of functions,” said Jogendra Siyag, one of the Event Heads. This round tested the ingenuity of the participants, since they had the creative freedom to design models according to their choice. It was indeed very challenging, and the participants walked away from the event with a better understanding of AutoCAD and 3D modelling.

Hydronomics

Hydronomics saw participants making and testing out their hydraulic-powered RC cars through different trails and terrains. Conducted over a three-day period, it proved to be one of the most exciting events of TechTatva ’18. Starting with a run-of-the-mill aptitude test to filter out participants, the first day saw a modest turnout.

The first round was held at NLH, and the participants present seemed to be highly engrossed in their tests. The second day involved further testing to decide the final candidates who would go on to make their very own RC cars and fight it out to the finish. Basic hydraulics was taught to the participants and a small model was built by them.

Round two of the event saw a select few participants gather in the Basic Mechanical Workshop and attend an introductory class on RC car-making. Using nothing but cardboard, wires, batteries, glue, and their sheer wit, students were given two and a half hours to whip up their vehicles to battle it out. Points were awarded based on the time it took for the contestants to complete the task. In the final stage of the competition, the crane that had been built were made to lift sand, with participants having to gather as much sand as possible using their newly-built RC cars. The event turned out to be a lot of fun for everyone involved, from the participants to the organisers. “Hydronomics was well-conducted and the participants enjoyed themselves—that’s all we could have asked for,” said Pritham G. Tendulkar, an Event Head, summing up the proceedings of the event.

Junkompresser

A fun event by Mechanize, Junkompressor aimed at getting students to understand vital concepts about compressors and IC engine structure by building exciting projects and then competing against each other. The first round comprised a written round and was a practical and informative round, wherein the teams had to build a car powered by air pressure.

It was supposed to be constructed out of empty cold drink bottles, pens, bamboo skewers, caps, and other items usually considered to be ‘junk’. The contestants had to use this newly-built car to take down ten bowling pins which had been fashioned out of used energy drink bottles. The winners of this round were decided based on the points scored in the written round and the numbers of pins (bottles) struck down in the practical round.

The final round, conducted in the Mechanical Workshop, witnessed a battle among the participants as they all had to build a compressor powerful enough to blow off sand and dust. Unfortunately, due to the motors not being powerful enough, the participants struggled to get going as the grains refused to budge. The teams kept working on their models and modified their designs to accommodate a less powerful motor, and soon the competition got going in full swing. The event utilised everyday objects to create ingenious models and was a success participants and organisers alike hoped will be replicated year after year.
