Here at the SBHS Robotics club, we compete at local, regional,
state, and even worldwide level tournaments for VEX Robotics.
Our club is constantly expanding and gaining new members.
I am currently a 10th grade student-athlete of South Brunswick High School who is part of the SBHS Robotics Team and the Track & Field Team. On the SBHS Robotics Team, I am a builder, meaning that I focus more on the building aspect of the robot rather than the programming part of the bot. As this was my first year as a member of the robotics team, I planned on absorbing all the knowledge I needed to be successful for next year's competition from my mentors and coaches. In my free time, I enjoy playing basketball and hanging out with my friends.
This is 750C (Cougars), one of the many SBHS Robotics teams, which I was part of for the 2018-2019 season of robotics.

This section shows what I have built or assisted in building during the 2018-2019 season,
as well as the game for this season.
VEX 2018-2019 GAME: TURNING POINT
VEX's 2018-2019 Game, Turning Point, is composed of two alliances, one red and one blue, with two teams making up each alliance. The objective of the game is to outscore the opposing alliance by flipping/stacking caps, toggling flags, or parking on the platform. The game is a total of two minutes long, with 15 seconds dedicated to an autonomous period (no driving permitted) and the rest to a driver control period.
COMPETITION SEASON: CATAPULT (ASSISTED)
When we changed to a catapult shooter on our reworked robot for the Sicklerville competition, the gearbox was a bit wide, as that did not really affect that bot's performance when competing. However, after competing with this shooter, we noticed that the size of the gearbox was actually ineffective with our current catapult design, as the bigger width meant that the rubber bands were pulling too much on the catapult, making our shots overshoot the flags. In order to fix this problem, Rohan and I decided to shrink our gearbox by changing our gearing and ratchet placement. Below is a picture of our gearbox before and after rebuilding. As you can see, the gearbox to the right is substantially smaller than the gearbox on the left.
SBHS SCRIMMAGE: HARVESTER INTAKE (ASSISTED)
One of the rudimentary and necessary parts to any successful robot competing in VEX's Turning Point was to have a good method to intake balls. For the SBHS Scrimmage, we decided to take our experience and knowledge from over the competition season to create a harvester intake, as throughout the entirety of the competition season, we noticed the most successful and efficient robots were the ones that used a harvester intake. I worked on the second harvester (the middle one) of the bot and also relocated the position of the third harvester (the top one). Below are pictures showing the harvester intake and a video showing a harvester intake test with the first two harvesters.
SBHS SCRIMMAGE: FLYWHEEL ATTEMPT (MAIN)
For the SBHS Scrimmage, our first idea for a shooter for our robot was a single flywheel. But due to the short amount of time and limited parts that we had for this scrimmage, we decided to go with a linear puncher instead, as it would be faster and more parts efficient than a single flywheel. On our single flywheel attempt, I had built the single flywheel and the gearbox that was needed for the flywheel, which included all the gearing that was required to make the flywheel spin fast enough to shoot a ball fast enough to toggle a flag. Below is a picture showing our initial attachment of the flywheel to our bot and a video (Rishi helped test the shooter) demonstrating the speed of the flywheel I had created. The gearing of the flywheel, from the motor to the wheels, is 6:3:1, which is essentially 18:1.
