TechTatva’17 — Kraftwagen

Crash Course
Athulya Mohandas Menon

A new initiative by Kraftwagen, Crash Course was an exciting event that tested a student’s knowledge of mechanical stress development and management. The event aimed to find the most aerodynamically and structurally robust chassis design for an automobile which could also withstand collisions.

Participants were taught the methods to reduce mechanical stress at a workshop conducted by the organizers, pre-TechTatva. They were also given a quick overview of how to use design tools like CAD and CATIA. The twenty participating teams were then asked to design a chassis on the design software, CATIA. The designs were put through a simulation and the two best ones proceeded to the final round. The teams were asked to explain their design choices, while their models were tested in a real-life collision situation.

The team comprising of  Rishabh Agarwal and Sanjay Bannerjee, secured first place after successfully crash-testing their chassis, which was able to retain its structure and not succumb to the pressure applied. Krutika Deshpande and Sahana Nag, both first-years who bagged the second prize, remarked, “The organizers were very helpful and taught us everything from scratch. In the end, the event helped us learn more about design.”

“Owing to the fact that they finished the chassis at 4 AM, I think both the teams did a very good job,” notes Himanshu Malik, the Category Head. The organizing committee was satisfied with both the turnout and the performance of the participants. Here’s to hoping that this event goes on to become an integral part of TechTatva in the years to come.

The first round of Kraftwagen’s ‘Hydrophilia’ took place on a Day 1 of TechTatva ‘17. The event was held in the Food Court pool and attracted a considerable audience. Eight teams participated in the first round, with each team consisting of a maximum of four people. In this round, the boats designed by the teams had to navigate an obstacle course in the shortest time period possible. Points were awarded or deducted by the judges based on how the vessels fared against the obstacles, and whether they were successfully surpassed.

The final round of the event saw the six teams with the highest scores in the first round battle it out in the Food Court pool for dominance over the water. Armed with weaponized ships and the will to brave it out in the blazing sun, the finalists provided excitement aplenty for the average onlooker.

The event organizers had demonstrated the process of making a ship that could complete the obstacle course and perform the necessary tasks during the Pre-TechTatva workshops. Participants were expected to have basic knowledge of electronics and mechanics. Equipped with four 300 RPM motors, the ships were powerful enough to navigate their way through the turbulent waters of the pool outside the Food Court.

According to Prateek Pati, the coordinator of the category, Hydrophilia saw some amazing ships being made this time around with the majority of the teams performing up to the mark during the first round. Pati also hailed the efforts of the second year organizers, who helped host the only water-based event of TechTatva. The event took a hit on the third day of the fest when the rain gods showed no mercy and had to be shifted to the last day.

The event also saw participation from an outstation team from Nitte University, Mangalore. Their team leader, Abhishek mentioned that they received a lot of help from the Kraftwagen event organizers due to their absence from the workshops. Despite the apparent hindrance, Abhishek and his team managed to achieve a great timing upon finishing the course.

Clawstruck, under the category Kraftswagen was an exhibition of the participants’ skill in robotics. The event took place on the street opposite the Dept. of Chemical Engineering building and was a complete success. The competing bots had to go through a variety of innovative challenges which made for a fun event.

The event was preceded by a workshop during Pre-TechTatva. Participants were given a kit with the materials and components required to build the bots. Sessions were held to explain the theory and procedure to build them. Following this, there was a week-long period in which participants could visit the automobile workshops to actually construct their machines under the guidance of the organizers.

The first round of Clawstruck on Day 2 saw the bots compete on an obstacle course with points based on a number of obstacles cleared and time taken. Initially, the obstacles were proving to be too much for the bots to handle, but the organizers’ quick thinking with some modifications made for a successful event. Four teams were selected for the second round, in which the bots had to use their claws to pick up 4 objects and place them in different spots on a complex track.

The final round had the top two teams of the second round compete in a race. The bots had to pick up their objects from their base and place it on the opposite team’s base. It made for an adrenaline-filled end to a very engaging Day 4 of TechTatva. Clawstruck was an engaging display of the participant’s mechanical and electrical skills, and also their driving skills.
