Autonomous Robot with Advanced Navigation and Object Manipulation 

 My Technical Contributions

Software Leadership

I took ownership of the robot's core functionality by:

• Writing all lower-level code and robot control systems in C++

• Developing autonomous navigation and line-following algorithms

• Implementing task-specific solutions.

• Implementing Robot arm control algorithms. 

Problem-Solving in Action

Real-time Adaptation to the Hidden Task

One of my proudest achievements was successfully coding a solution for the hidden task with only 30 minutes of preparation. When the previously undisclosed challenge was revealed during the competition, I quickly analyzed the requirements and developed a working solution within the tight timeframe. We were the only team that completed this challenge successfully. 

Technical Challenges Overcome

I played a key role in solving several critical issues:

• Bidirectional Line Following: Designed and implemented a dual IR array system that enabled effective line following in both forward and reverse directions

• IR Sensor Isolation: Diagnosed interference issues with the IR sensors and collaborated on a hardware solution that significantly improved sensor accuracy

System Architecture

My code architecture for the robot included

• Modular task-specific algorithms that could be quickly selected and deployed

• Real-time sensor data processing 

• Efficient state machine implementation for complex decision-making

• PID control systems for precise motor control and line following

Results

The reliable and adaptable codebase I developed directly supported our team's success in the competition. The robot demonstrated exceptional performance in:

• Line navigation of varying widths

• Maze solving with box manipulation

• Color and dashed line following

• Timed portal navigation

• Uneven terrain traversal with precision coin placement
