Autonomous Ultrasonic Mini Robot

What I Built

Built a mini robot that continuously moves around and uses an ultrasonic sensor to detect obstacles and adjust its behavior.

My Role

Sole Creator

Tools / Tech

• Ultrasonic sensor
• Microcontroller
• Motors
• Autonomous navigation logic

Build Process

• Connected the ultrasonic sensor and motor system.
• Wrote logic that allowed the robot to keep moving while reacting to obstacles.
• Adjusted behavior through testing so the robot could operate continuously.

What I Learned

• Learned the basics of autonomous sensing: reading distance data and turning it into movement decisions.
• Connected sensors, motors, and code into a single feedback loop.
• Discovered why even simple robots need careful testing.

Result / Impact

This project helped me understand the foundation of autonomy: sense, decide, act, and repeat.
