In the Motion Conversion Challenge my partner and I utilized our new knowledge in calculating efficiency & GR (Gear Ratio) to Design, Build, & Test a machine that would be able to accomplish a high efficiency, thus making it easier to lift a minimum of 500g. While designing our machine we want to use a mix of a inclined plane, pulley, and gear system that would mimic a similar use such a winch used for rescues. Overall our machine worked and accomplished our goal of attaining a somewhat high efficiency.

In the Electric Vehicle (EV) Challenge, my partner and I used what we learned about capacitors and circuits to Design, Build, and Test a battery-powered car that could travel the farthest distance while being timed by a discharging capacitor. We ran into some problems, like the motor not staying in place and circuits not working consistently, but we fixed these problems by using a pulley system to make the car more stable and efficient. In the end, our car worked and met the project goals, showing what we could do with the tools and knowledge we had.

In the Vault Project I used my knowledge of Mechanical design, electrical circuits, and coding to develop a traditional box shaped vault/safe. During development my partner and I were reviewing all the potential shapes we could use, In the end we chose A traditional cube box over a pyramid design to make the body simple to manufacture. When It came to circuits we used an Arduino and two bred boards 1 for the LEDs to indicate lock status, and one to control the motorized lock and dial to unlock the door. Lastly we used Arduino Code (C++) to control the LEDs and motor. Once we completed building our safe we found issues mainly consisting with the motors reliability. Fortunately we were able mitigate the problems with the motor, thus causing our safe to lock and unlock reliably.
When tasked on designing and building a surgical robot, my goal was to make the design as simple as possible in all aspects to reduce the number of problems that could occur while also increasing reliability. To do that we opted in using a rotating base to make 180 degree turns, a lead screw to make the claw move up and down about the y-axis, and a claw to grab and release the surgical tool. My goal when designing the custom claw tips was to increase accuracy when trying to grasp smaller instruments, so I made the claw tips thin and wide to help with leverage. When coding I ran into only 2 problems; first when attempting to make the base rotate with the potentiometer, and second when attempting to make the servo open and close the claw. My first resolution was to make the base rotate when the potentiometer is being turned in its respective side rather then turning with the potentiometer exactly, which ended up being more convenient for the operator. Secondly For the claw we limited the full 90 degree motion to just 10 degrees which made the servo work, but at the cost of wider reach. Overall this project turned out to be a great success.

During a collaboration with welding I was tasked to model a design created by the welding team. Our goal was to make a grill that was simple but still worked well for cooking and cleaning. We went with a circular base and a cone lid to help spread the heat evenly and trap smoke. In the body we added a door to make it easier to clean out the charcoal without taking the whole thing apart. I modeled the grill in SolidWorks and tried to keep the design as basic as possible so it would be easier to build. The first problem I ran into was getting the lid to sit right on the base without sliding or overlapping, and I fixed it by adding a small lip around the top. The second issue was making the cut for the door fit the curve of the body, which took a few tries using surface cuts until it worked right. After finishing the model I gave it to the welding team to build and overall the grill came out clean and worked just like we hoped.

To wrap up junior year, I was tasked in designing my own home. the goal was to implement 10 architectural vocabulary words into my design. Out of all my options I decided to design and build a modern A-Frame home. I wanted my house to promote a sustainable and minimalistic look, by allowing natural resources such as sun light to enter the home reducing the need for artificial light.
Narrative:
The A-Frame is a residential architectural style that became popular in the United States in the mid-20th century. It resembles a symmetric and clean design of modernism and brutalism architecture which was popular during its time. The goal for Modernism is to embrace sustainability by reducing energy consumption by using features such as larger windows to allow more light in to prevent the need for more artificial lighting. Most A-Frame homes have a steep triangular roof stemming from the bottom and goes up until the top of the frame. Many A-frame homes are built out of wood, but modern A-frame homes use cladding to cover the wooden frame to give a minimalist look. On the Facade (front)
Above is my model of a Modern A-Frame home. My model has a simple design yet still has important features such as a steep roof, an abundance of windows on the front and a big window on the side. On the Facade (front) the model is full of triangular (fixed) and rectangular windows, such as double hung windows that open up to allow fresh air to enter the home. The bottom windows can slide to give the model home an open type of feel. On the side right side of the A-frame Model a large fixed glass window will stem from the ground up until the tip of the frame allowing natural light to enter every inch of the model, adding onto the open feel of the home. On the bottom floor a cantilever will stem out of the home serving as a porch, which will compliment the modern design on the model. The left side of the A-Frame will extrude out a bit more than the right side creating a curtain wall to cover the porch. Lastly the facade of the home will be covered in cladding to add onto the modern design.
