Building an Autonomous Robotic Vehicle
summary
Builds a working autonomous rover named Coffee using Java on a Raspberry Pi with Pololu 25 mm metal gear motors, RoboClaw motor controllers, quadrature encoders and a PCA9685 PWM board for servos. Uses a low‑cost LIDAR (initially $89, later ~$150) plus an Adafruit IMU and GPS; many algorithms are developed offline by replaying sensor logs recorded with Java Flight Recorder. 3D‑printed chassis and custom wiring work; overall system runs and navigates but required tuning and a few toasted Pis.
