Robot Specification:
A Line Follower shall not exceed 25 cm in overall length, 25 cm in overall width and 25 cm in overall height. The electric supply voltage on the bot must be lower than or equal to24V at any point during the time of the game. The bot must have on-board power supply. No external power supply (230V) will be provided. The team will have to take care of the stock of the batteries. Organizers are not responsible for the availability of the batteries near the event location.
Timing of Laps:
The time it takes for a Line Follower to make the circuit of a track shall be the recorded lap time. To determine the lap time of the Line Follower, the period from the time the sensor at the starting line detects part of the Line Follower body to the time the sensor at the finishing line detects part of the body of the same Line Follower shall be clocked. However, no measured lap time shall be regarded as valid unless the entire body of the Line Follower passes through the finishing line.
The Line Follower shall have a specified maximum number of attempts to run the track within a stipulated time limit (typically 3 to 5 minutes and from 3 to 4 attempts to be decided by the organizer on the day of the race). If the performance time limit is reached and the Line Follower is in the midst of a run, the Line Follower will be allowed to complete the run and the lap time will be valid if the run is successful. Within the given performance time, the handler is allowed to replace batteries and/or upload new program parameters to the Line Follower.
Autonomous Control:
Once a robot has crossed the starting line it must remain fully autonomous, or it will be disqualified.
Arena Edges:
A robot that wanders off of the arena surface will be disqualified. A robot shall be deemed to have left the arena when any wheel, leg, or track has moved completely off the arena surface.
Losing the Line:
Any robot that loses the line course must reacquire the line at the point where it was lost, or at any earlier (e.g. already traversed) point.
Characteristics of the line course:
The line will be black and 3 cm thick throughout the arena.
There will be no crossovers (e.g. places where the line crosses itself).
Switchbacks and hairpins are possible, but the adjacent sections of the line shall be no closer together than 15cm when measured from the center of each line.
Sharp angles may occur, but will not be smaller than 90°.
Organizers’ Decision:
The organizers reserve the right to make changes to any of the above in the interest of fair play and sportsmanship, and to ensure that all competitors have an enjoyable competition.
In the event of ambiguity, the organizers’ interpretation of any clauses of the rules shall prevail.
No objections shall be declared against the judges’ decisions.
