What it can do
Written by Robotheca from the project's documents.
- Follows a black line on the ground using an IR sensor array and PID-based control logic.
- Drives two DC geared motors through an L298N motor driver.
- Detects obstacles with an ultrasonic sensor.
- Operates a servo-based ball-putting mechanism.
- Uses a custom laser-cut metal chassis of 35 x 30 cm with 3D-printed mounts.

Wiring and electronics
Notes written by Robotheca from the project's documents.
Main parts
- Arduino Uno as the main controller.
- L298N motor driver for the DC motors.
- DC geared motors for movement.
- IR sensor array for detecting the black line.
- Ultrasonic sensor for obstacle detection.
- Servo motor for the ball-putting mechanism.
- 4-cell battery pack as the power source.
Connections
- The circuit layout is documented in a Fritzing file in the circuit folder.
- The L298N driver is mounted on a 3D-printed base to isolate it from the metal chassis and reduce short-circuit risk.
