Implementation of a Maze-Solving Robot

[Vaibhavsul]

I'm trying to build a maze-solving robot using three ultrasonic sensors. Can someone guide me on the components I should use?

- Should I use three ultrasonic sensors or one ultrasonic sensor with a servo motor?
- What other components should I consider, like an OLED display for showing the status (maze scanning or solving) or LED indicators?
- Which microcontroller should I use for better accuracy?
- How should I write the code, and which algorithm should I use?
- Which chassis is better a three-wheel or a four-wheel or any other?
