The miniature bascule bridge using Arduino, servo motors, and buttons is most definitely a creative project. It effectively simulates the lifting mechanism of a real bridge, with servo motors allowing controlled movement and buttons providing simple manual input. However, it lacks indication, as it doesn't include leds or even a counterweight system. The limited torque of servos may also reduce performance and accuracy, but overall this project serves its purpose, and can lead to future architectural innovations

The automatic alcohol dispenser was able to consistently accomplish its task with no interruptions and precisely achieve dispensing alcohol, with great satisfaction. However, one design drawback is that refilling the alcohol dispenser proves difficult due to the lid being hard to open and put back. The next prototype will hopefully make it easier to refill the dispenser with ease.

The automatic alcohol dispenser is a very helpful and smart way to help people stay clean and maintain good hygiene. The design is simple and works well by using basic physics concepts like motion and energy. The feedbacks from users show how great the performance of the dispenser is. However, it can be improved if the alcohol is easier to refill without the risk of getting the wires wet. This project is successful and it shows how physics can be used to support healthy habits in our everyday life.

This project utilized the basic physics concept as we used different components used in robotics, like the ultrasonic sensor. It is hygienic and easy to use, and it also promotes better sanitation as it is automatic and doesn’t require touch. It can dispense just the right amount of alcohol to be able to clean our hands, though its response time can be inconsistent at times. According to my groupmates, with a few adjustments, like fixing the design and more testing, this project could be way better. Overall, this project does its job, and it is very useful to have around.

This design of automated alcohol dispenser shows a practical innovation that is very helpful, especially in our current situation where disease remains one of our major concerns. It shows the application of physics, like the ultrasonic sensor, which reduces physical contact, and improves hygiene.

# data[].attributes.body
The calibrations and construction of the entire contraption where deemed successful as the basic functions performed as expected. Both efficiency and practicality were observed in the setups, providing a clear insight of the results. More specifically, the sensors showed no apparent interferance from different environments, as long as contact was within range. Furthermore, it passes the description and criteria of an automatic alcohol dispenser. Although improvements to the structure's integrity and ergonomics should be accounted for since external damage is very likely to happen.

This project is well made and highly beneficial for maintaining hygiene and cleanliness. The automation feature is especially commendable, as it eliminates the need to touch surfaces which significantly reduce the risk of spreading germs. One suggestion for improvement would be to adjust the alcohol pump time to ensure the right amount is dispensed efficiently.

The design is hygienic and contactless, which aligns with safety measures we have to follow since bacteria and viruses are present anytime. It has a simple design and is easy to use, with just a wave of hand, a small amount of alcohol will be given. For stability, a base or a platform on the bottom can be added to avoid tumbling, as well as for protecting internal parts.

This automatic alcohol dispenser is a smart and useful idea, especially now that we still worry about sickness. It helps keep us safe by using technology like sensors, so we don’t need to touch anything. This makes things cleaner and safer for everyone. One way to make it better is to make refilling it easier without getting the wires wet, it avoids damage because water or alcohol can damage the wires or electrical parts inside the dispenser, making it stop working.

The addition of a rubber bottom to the pencil sharpener is a practical and effective design improvement. It helps keep the sharpener stable on surfaces, preventing it from slipping during use. This added grip makes sharpening pencils easier, safer, and more comfortable, especially for students or frequent users. It also minimizes the risk of accidents and reduces the need to hold the sharpener tightly. Overall, it’s a small change that greatly enhances user experience and functionality.

# data[].attributes.body
Adding a rubber boot to a mechanical sharpener is an effective way to improve stability by increasing friction with the surface, reducing slippage, and enhancing user safety and comfort. It also helps protect surfaces from scratches. However, its effectiveness depends on the quality and durability of the rubber, as low-grade materials may wear out over time. While it improves external grip, it doesn't address internal mechanical stability and may slightly reduce portability. To enhance performance, features like textured grips, and better materials could be considered.

# data[].attributes.body
Although the sharpener is already designed for mobility, the rubber reinforcements present more opportunities of ergonomic innovation. With this addition, the usage of the sharpener deems to be more efficient, as no movement is wasted, by the improved grip due to increased friction with flat surfaces. The overall design promotes ergonomic movement, along with longevity as the rubber bottom provides minimal durability to the object's structure. One flaw it could work on is reducing the entire movements produced by the usage of the sharpener, even if it is already minimized. Ultimately, the design is feasible enough to be used daily efficiently.

Adding rubber to the bottom and grip of the mechanical sharpener makes it easier to hold and stops it from slipping for your hands to not get tired quickly. It might still take a little effort to turn the handle, but this helps you sharpen the pencil nicely and evenly which many users, especially students, like because it works well and gives good results every time.

The servo motor bascule bridge is a creative and functional model. It shows how simple machines and tech like Arduino can work together in a fun and hands-on way. The buttons make it easy to control, and it’s satisfying to see the bridge actually move. It’s a great intro to automation and electronics. Of course, there are a few small things—like the servo’s limited movement and how the materials might not be super sturdy—but overall, it’s a creative and impressive build that really brings the concept to life.
