Robo Hockey Challenge

Dimensions
The robot must fit inside a 30cm × 30cm × 30cm cube.

Weight
Maximum weight: 7 kg (including batteries). 5% tolerance allowed.

Power Source
• Electric only (battery‑powered motors)
• Maximum battery voltage: 48V

Control System
• Wireless (Remote‑Controlled)
• Allowed frequencies: 2.4GHz, 900MHz, 75MHz

Interference Rule
Teams must not interfere with tournament Wi‑Fi or other teams’ radio signals. Violation may result in disqualification.

Mobility Requirement
The robot must be capable of multi‑directional movement (not limited to one axis).

A standard weighted hockey puck will be used.

Restrictions
• No Engulfing: Robots may not fully surround or trap the puck. A visible portion of the puck must remain visible from above at all times.
• Dribbling: Pushing and controlled pulling are allowed. Adhesives, suction, or magnetic holding are strictly prohibited.
• Kicking Mechanism: Mechanical kickers or flippers are permitted.

Two vs Two Match (Main Format)
• 2 robots per team
• Total match duration: 10 minutes (two halves of 5 minutes each)
• 1.5‑minute break between halves
• Continuous clock (except referee intervention)

Late Arrival Rule
Teams must report 5 minutes before match time. Late arrival may result in 1 goal penalty per minute. Failure to appear within 5 minutes = Forfeit (5–0 loss).

One vs One Match (Special Round)
• 1 robot per team
• Match duration: 2 minutes (no breaks, continuous clock)
Focus areas: Speed & agility, ball handling precision, offensive & defensive control.

Match Start
Robots begin on their respective sides. The umpire places the puck at center line. Movement begins only after official signal.

Continuous Play
After a goal: a new puck is placed immediately – no regrouping break.

Scoring
• Normal Goal: Puck must completely cross the goal line.

Illegal Conduct
Attacking a disabled or flipped robot is prohibited; may result in removal for the rest of the round.

Dead Robot Rule
If all robots stop functioning:
• In Period 1 or 2 → Round ends early, standard repair break applies
