My contributions included:

• Selected and resized a pre-designed 3D model from Tinkercad to fit the official sumo arena dimensions, ensuring proper scale and alignment.
• Built the hardware using Arduino Uno, H-bridge motor driver, an ultrasonic sensor for detecting opponents, and an IR sensor for tracking arena boundaries.
• Programmed the robot using the Arduino IDE, integrating sensor logic, movement control, and arena awareness.
• Conducted testing and iterations to validate functionality and ensure responsive, stable performance in the sumo competition environment.
• Achieved 2nd place out of 23 teams in the sumo robot competition, demonstrating strong design, hardware integration, and performance.
