Unveiling the History: From Shannon's Theseus to Modern Marvels

The quest for autonomous maze-solving machines has a rich history. In 1952, mathematician Claude Shannon, a pioneer in information theory, constructed an electronic mouse named Theseus. This early marvel, guided by a computer embedded within the maze itself, demonstrated the fundamental principles of machine learning by memorizing the correct path through trial and error.

Fast forward to 1977, the Institute of Electrical and Electronics Engineers (IEEE) announced its "Amazing Micro-Mouse Maze Contest." Inspired by a misunderstanding about "electronic mice," this competition ignited a global movement. While the initial entrants faced significant challenges, by 1979, the finals captivated a nationwide audience, marking the true beginning of the Micromouse competition as we know it today.


The Competitive Spirit: More Than Just a Race

As a Veritasium-esque exploration reveals, the tension and dedication within the Micromouse community are palpable. The difference between victory and defeat can be mere milliseconds, fueling an intense competitive spirit. Participants pour countless hours into refining their designs and algorithms, driven by the pursuit of honor and the thrill of innovation.


The Anatomy of a Micromouse: Small Size, Immense Capability

A Micromouse operates under strict constraints. Each robot must be fully autonomous, fitting all its computing power, motors, sensors, and energy source within a compact frame no larger than 25 centimeters in either length or width. While height isn't strictly limited, the rules prohibit climbing, flying, or any form of combustion, ruling out dramatic propulsion methods.

The Micromouse maze itself is a square, approximately three meters on each side, meticulously divided into corridors just 18 centimeters wide. In 2009, a "half-size" category emerged, featuring even smaller robots (under 12.5 centimeters per side) navigating paths a mere nine centimeters across. The final Micromouse maze layout remains a closely guarded secret until the competition's start, preventing competitors from pre-programming solutions based on a known configuration. Once the maze is revealed, competitors cannot alter their robots' code, emphasizing real-time adaptability.

Major Micromouse competitions, such as those held in All Japan, Taiwan, and the USA's APEC, typically grant each robot a limited time (seven to ten minutes) within the maze and allow only five attempts to reach the goal from the starting point. This constraint necessitates a strategic approach, balancing exploration with the urgency of a timed run.


The Art of Maze Solving: From Simple Walls to Sophisticated Algorithms

While the concept of maze solving might seem straightforward, the limited sensory input of a Micromouse (often relying on just a few infrared sensors) transforms the challenge. Early competitors experimented with simple wall-following algorithms. However, to increase the complexity and demand more intelligent navigation, maze designs evolved to include goals away from the edges and free-standing walls, rendering simple wall-following ineffective.

More advanced strategies emerged, mirroring classic graph traversal algorithms. Depth-first search encourages the robot to explore deeply into the maze, backtracking only when a dead end is reached. While guaranteed to find the goal, it often doesn't yield the shortest path. Breadth-first search, conversely, explores all paths at a given "depth" before moving deeper, ensuring the discovery of the shortest route but often requiring extensive backtracking and re-traversal.

The most prevalent maze-solving algorithm in Micromouse competitions today is the "flood fill" algorithm. This ingenious approach involves the robot creating an internal map of the maze, initially without any walls. It then optimistically plots the shortest path to the goal and begins its run. When the robot encounters a wall not present on its internal map, it updates its map and recalculates the shortest path. This continuous process of running, updating, and re-planning, always aiming directly for the goal along the numerically decreasing "distance" gradient to the target, gives the algorithm its name. The "flood" analogy represents the way distances to the goal are conceptually propagated through the maze.

By treating its return trip to the start as another learning opportunity, the Micromouse can further refine its internal map. Through these optimized forward and backward journeys, the robot becomes highly adept at identifying the true shortest path, often without needing to explore irrelevant sections of the maze.


The Evolution of Speed: Beyond the Shortest Path

Once effective maze-solving algorithms like flood fill became commonplace, coupled with readily available microcontrollers and sensors, some observers in the late 1980s believed that the Micromouse competition had reached its peak, with the core problem seemingly solved.

However, the 2017 All Japan Micromouse Competition showcased a paradigm shift. While the silver and bronze medalists both found the geometrically shortest path and navigated it in an impressive 7.4 seconds, Masakazu Utsunomiya's winning robot, "Red Comet," took a significantly longer route – a full 5.5 meters more. Red Comet's triumph highlighted a crucial realization: Micromouse isn't solely about finding the shortest path; it's about achieving the fastest path. Red Comet's sophisticated search algorithm determined that its longer route, with fewer turns to impede its speed, would ultimately result in a quicker overall time. This strategic decision, a calculated risk, paid off, securing victory by a mere 131 milliseconds.

This demonstrated that optimizing for speed, even if it means traversing a longer distance, is a critical element in achieving the fastest maze solving robot performance. Now, differing routes based on speed optimization are increasingly common in competitions.


The Relentless Pursuit of Innovation: Hardware and Beyond

The evolution of Micromouse isn't limited to software. Over the years, significant advancements in hardware have also played a crucial role. Early, bulky wall-sensing arms gave way to compact arrays of onboard infrared sensors. Less precise stepper motors were replaced by powerful continuous DC motors coupled with encoders for accurate feedback control. Gyroscopes, a technology popularized by mobile phones, provided an additional layer of orientation awareness, making turning maneuvers more reliable by relying on the gyro rather than just wheel encoder pulses.

Despite these mechanical upgrades, a persistent challenge for decades was the impact of dust on the robot's wheels. The minuscule change in friction caused by accumulated dust could significantly impair a run at the high speeds and precision involved. Competitors universally adopted the practice of meticulously cleaning their robots' wheels with tape between rounds.

As Micromice became increasingly fast in the early 2000s, the limiting factor shifted from raw speed to controlling that speed, particularly during turns. To prevent slipping or flipping, robots had to maintain a low center of gravity and decelerate significantly while cornering, much like race cars needing centripetal force to stay on track.

This limitation spurred another significant innovation, often referred to as Micromouse's "second Fosbury flop." The introduction of a vacuum fan, initially seen as a gimmick when Mokomo08 first employed it, revolutionized grip. By generating a powerful downward force – up to five times the robot's weight using repurposed drone motors – these vacuum-equipped Micromice could achieve centripetal accelerations approaching those of Formula 1 cars, allowing them to corner at much higher speeds without losing traction. This innovation allowed builders to push the speed limits even further, with some Micromice capable of accelerating faster than a Tesla Roadster (albeit for a short burst) and reaching speeds of up to seven meters per second.


The Future of Micromouse: Endless Possibilities

Every standard feature of the modern Micromouse was once an experiment, and the next groundbreaking innovation is likely just around the corner. From the first four-wheeled Micromouse winner in 1988 to current explorations in six- and eight-wheel designs, omnidirectional movement, and even computer vision, the field remains ripe with possibilities.

For those intrigued by the world of Micromouse, getting started doesn't require advanced knowledge of vacuum fans or intricate wheel configurations. According to enthusiasts, it's the "perfect combination of all the major disciplines that you need for robotics and engineering and programming, embedded systems, all wrapped up in one accessible bundle that you can do in your living room." Curiosity is often the initial spark that ignites a fascinating journey into this captivating domain.

In essence, Micromouse, at its core, is about a miniature robot attempting to solve a maze. However, nearly half a century into its evolution, this seemingly simple problem serves as a powerful reminder that there's often far more complexity beneath the surface of even the most straightforward challenges.

If you're inspired to build your own maze solving robot, tools like Onshape, a cloud-based CAD system (and sponsor of the Veritasium-inspired content), offer a fantastic platform for designing the necessary parts, from the robot's chassis to intricate mechanisms.
