Non-competitive. Participants are shown each expression on screen and the corresponding bot movement, so they can learn and practice the mapping before the timed rounds begin.

• No scoring and no time limit — this round is purely for practice.
• Participation in this round is mandatory for all teams before Round 2.
• Both duo members must familiarize themselves with all available expressions and their corresponding bot movements.

N/A (not a scored round).

Timed elimination round. Teams must navigate the bot through designated symbols or patterns using the expressions learned in Round 1. Performance is evaluated based on accuracy and speed. Teams scoring above the qualifying threshold advance to Round 3.

• One expression prompt or direction is shown at a time, with the sequence randomized for each team.
• Each prompt allows exactly one attempt — no retries or re-dos.
• A correct and clearly detected expression match earns one point.
• Each prompt must be completed within the specified time limit.
• Relay is allowed — both duo members may take turns at the webcam station during the run.
• Top-scoring teams or teams scoring above the qualifying threshold advance to Round 3.

Minimum and optimized movements will be considered to determine the winner in case of a tie.

Qualified teams from all sessions compete in a timed maze race. The team's bot starts at a fixed point on a maze grid. Each detected expression triggers the corresponding movement. Teams must chain expressions correctly to navigate around walls and reach the finish tile in the shortest possible time.

• Each expression maps to one fixed directional action for the bot.
• A move registers only when the expression is held clearly and detected with confidence; brief or accidental expressions do not trigger movement.
• Moving into a wall results in no movement, and that turn is forfeited.
• Teams may choose to run the maze solo or use a relay. The choice must be declared before the run starts and cannot be changed during the run.
• Backward movement is not permitted.
• The first bot to reach the finish tile within the time cap wins.
• If no bot reaches the finish tile within the time cap, the team that covers the greatest distance from the starting point wins.
• The winner and runner-up for the day are decided based on the best completion times.

Round 2 score, number of bot crashes, and navigation efficiency will be considered.
