Inspiration
Inspired by the Olympic Biathlon, we built a robot that balances high-speed navigation with precision obstacle avoidance. We wanted to move beyond basic line-followers to create a system that actively reacts to its environment.
What it Does
The bot is a dual-purpose autonomous vehicle. It uses a color sensor to track a specific course and an ultrasonic sensor to navigate around obstacles. It "sprints" on the track and shifts to "precision" mode when an obstacle is detected.
How We Built It
We used an Arduino R4 Minima as the brain. The hardware includes an HC-SR04 ultrasonic sensor and a DC motor array. The steering logic relies on a feedback loop to minimize the error between the sensor reading and the target path.
Challenges & Lessons
We faced many hurdles when building the robot. The hardware provided was often faulty and prone to breakage, and the Arduino parts provided were inconsistent at times. The software was also difficult to work with due to the faulty and inconsistent hardware, and we were also constrained by factors such as inconsistent surface terrain.
