Vacuum System (50,000 RPM):

The high-speed vacuum fan used in the robot generates a strong negative pressure between the robot and the ground, maximizing surface adhesion. Despite its lightweight and compact chassis, the additional friction force provided by the vacuum system prevents wheel slip, especially during high-speed sharp turns and narrow corridor maneuvers. As a result, the robot maintains a stable and predictable driving behavior throughout the maze.

Wheel and Motor Speeds (2,000 RPM):

Considering the wheel diameter of approximately 23 mm, these rotational speeds indicate that the robot is theoretically capable of achieving very high linear velocities. Since speed in maze-solving applications must be balanced with control, the robot is optimized for rapid acceleration on straight paths and controlled deceleration during turns. This balance minimizes error margins while delivering high overall performance.

Sensor Configuration (3 Sensors – 45° Angled Placement):

The robot is equipped with three distance sensors strategically positioned to detect maze walls effectively. The 45-degree angled placement allows simultaneous detection of both front and side walls. This configuration enables early recognition of upcoming corners, narrow passages, and potential dead ends, allowing the robot to make smarter and more stable navigation decisions.

Weight Distribution and Chassis Layout:

The motors and vacuum fan are positioned close to the wheel axis to keep the center of gravity as centralized as possible. This design reduces the robot’s moment of inertia during turns and minimizes instability during sudden direction changes. Consequently, the robot delivers balanced, fast, and controlled motion even in sharp cornering scenarios.

Algorithm and Control:

The microcontroller-based control system processes sensor data in real time to execute maze-solving algorithms. During wall-following and directional decision-making, the vacuum system and motor speeds are jointly optimized, ensuring superior performance in both speed and accuracy.
