IEEE RAS HTU Student ChapterMMRC 26

Rulebook

The rules in full. The diagrams are live — re-roll the maze, compare the two run types, and check your chassis against the footprint limit.

Run the readiness checklist

Eligibility

MMRC 26 is open to all currently enrolled university students, individually or in teams of up to four. Each team may enter at most one micromouse.

The maze

The competition maze is a 10×10 grid of 18cm cells with 12mm-thick walls, built with IEEE micromouse standard cell and wall dimensions. The start cell is in a corner; the goal is a 2×2 block at the maze center.

The layout is not published in advance. Every maze below is a fresh one, generated the moment you loaded this page — press New maze to see another.

The competition maze

Every maze is different, but the geography never is: 10×10 cells, one start corner, and the goal room dead centre. The competition maze is not published beforehand — this is a fresh one each time you press the button.

Runs

Each team gets up to five runs. A run ends when the mouse reaches the goal, hits the time limit (10 minutes), or the team retires the run. The fastest successful run counts.

Scoring

  • Search runs may explore freely and are not timed against the leaderboard.
  • Speed runs must use only cells already discovered on a prior run for that team.
  • Final ranking is by best speed-run time; ties are broken by best search-run time.

That second point decides more places than any other rule, so it is worth seeing rather than reading: a speed run is only ever as good as the search that came before it.

A search run, then a speed run

The first run explores. It wanders, doubles back, and is not timed against the leaderboard — but every cell it steps on is a cell the next run is allowed to use.

Robot rules

  • Maximum footprint: 25cm × 25cm at any rotation.
  • No jumping, climbing, or damaging maze walls.
  • Autonomous operation only — no remote control or manual intervention once a run starts.

Will your mouse fit?

The dashed square is the 25cm × 25cm limit; the solid one is a single 18cm cell. Measure your widest points — wheels, sensors and bumpers included.

Conduct

Unsportsmanlike conduct, maze tampering, or rule violations may result in disqualification at the judges' discretion. Judges' decisions are final.
