This project is about a Walking Mechanism that looks like an insect. Walter uses the same technology as the Vbug 1.5 (also known as Walkman), a famous 6-legged robot created by Mark Tilden (The founder of beam robotic). Walter and Walkman's movement and behavior are like insects. They prove that we can create many different robots that can copy various animals' actions and behaviors. Walter is only able to walk, avoid the objects, and detect the light. It is an excellent robot for beginners to build because you'll get a new experience, and it is not difficult to make one.

I wanted to build the Original Walker, with the capability to follow the light like a real bug, but I had no photodiodes, so I had to make some changes. My Walter is easier than the original one--only walks and avoid obstacles. Also, I had to use different components from the original. The electrical circuit and schematic are also different from the original Walter, but the code is the same.

My Walter can move, although it struggles to do it. The sensor works just fine, but Walter cannot avoid the obstacles. I feel accomplished because I was able to do my first robot. It is fun to build it. For the improvements I would make sure that the legs are at the same size and shape and try to use the Arduino pro mini and the smartphone power bank instead of the two 6V power supplies.

This project involves creating a circuit that can charge a mobile phone battery using an AC signal as a power source. I utilized an existing project as a reference to design and build my circuit. The goal was to convert an AC signal, simulating wall power, into a regulated DC voltage of 5V, which is the standard charging voltage for most mobile phones. To achieve this, I used a function generator to provide a 10 AC input and built a 5V regulated DC supply. Instead of using a transformer to step down the voltage from the wall, I opted for this approach as a safer alternative. The final circuit is capable of charging an Android phone battery.

In this project, my cousin Giovani DeOliveira and I collaborated to build a robotic arm using an Arduino Uno board and the Blynk software. The robotic arm was controlled by an app that allows for prototyping, deploying, and remote management of electronic devices. The code for the arm was written in the Arduino IDE using C++. The arm was designed to execute specific actions and movements, with the help of a series of motor servos powered by the Arduino board and connected to a computer. The servos were controlled through an algorithm written in the Arduino IDE, allowing the arm to move to specific positions. The end effector of the robotic arm, a gripper, was used to perform tasks such as picking up and moving objects.

The body of the robot was constructed using wood and the gripper was made from plastic, sponge, and a servo connected with a string. The building process was an exciting experience, and it required good teamwork, problem-solving skills, and creativity. We used an online project as a guide, but we made many modifications and came up with our own design. The project was built for fun and to gain experience, and therefore, no project document is available for download.

My minor in Computer Science required me to complete several projects as part of my coursework in different CS courses. These projects have required me to utilize my programming skills to create solutions for various problems. The courses in which I have completed these projects include CS110, CS210, and CS240, and the programming languages used for each course were Python, Java, and C, respectively. As a result, I have gained proficiency in multiple programming languages and have been able to improve my programming abilities. Furthermore, I have demonstrated my ability to deal with complex technical problems through these projects.
