Tinybit Maze Solving is an educational activity where the Tiny:bit robot car, powered by a micro:bit, is programmed to find its way through a maze using different methods. The robot can solve line mazes by following black lines with its infrared sensors, navigate wall mazes with ultrasonic sensors by applying rules like always keeping the left or right side close to a wall, or use memory-based algorithms to record movements, avoid dead ends, and eventually find the shortest path. This process helps learners understand robotics, sensors, algorithms, and problem-solving through hands-on practice.
