Fastest Line Follower Challenge

The participating bots must be wireless and autonomous. It can be circular / Rectangular in style. The bot must fit inside a box 20 centimeters in length, 20 centimeters wide, and 20 centimeters in height at any point in time. Maximum weight should not be more than 5Kgs including battery, however, a tolerance of 5% in weight is acceptable. Participants need to ensure:

• Batteries must be sealed, immobilized electrolyte type (gel cell, lithium, NiCad, or dry cells).
• The electric voltage anywhere in the machine should not be more than 16.8V DC at any point in time for each robot.
• Infrared light-reflecting materials must not be used on the outside. If robots are painted, they must be painted matte. Minor parts that reflect infrared light could be used only if other robots are not affected. Robots must not produce magnetic interference for other robots on the field.
• If a team claims that their robot is affected by the other team’s robot in any way they must show proof/evidence of the interference. Any interference must be confirmed by a Referee if a claim is placed by the other team.
• The robot must be autonomous.
• Robots must be constructed and programmed in a way that their movement is not limited to only one direction and must move in all directions.
• No wireless communication between the bot and the operator will be allowed. Bluetooth, RF Module, etc not allowed on the bot.
• Any robotic parts/building material can be used until the robot meets the above specifications and if the design and construction are primarily the original work of the team ready-made robots are not allowed to compete in the competition.

The Racing track of the Fastest Line Follower challenge has a track total length of 180 – 200 ft (approximately) on an arena dimension of 24X24 SqF. The width of the black line will be 25mm. The surface of the track will be white with a black line marked on it. The track may contain crossed, curved, or discontinuous black lines.

The start and finish points will be the same.

The timing of each run will be measured by an automatic timing system.

3D Model Arena: Move Cursor to View 360 degree

Start and Restarts:

• The robot will be placed at the starting point with the consent of the referee. The RACE CLOCK will start as soon as the robot crosses the starting point and will stop after the robot crosses the starting point again. This will be done by an automatic timing system.
• The bot may restart the run if the person handling it feels the necessity. A restart can be requested only if the robot doesn’t follow the line, has stopped halfway, or has lost the directions/Black line.
• At any restart, the robot must be re-positioned back at the start point.
• It is not allowed to reprogram the robot or to add/remove parts on the robot during the run, but adjusting the sensors is permissible with the consent of the referee.
• The RACE CLOCK/RUN TIME will reset to zero on every restart. The COMPETITION CLOCK (maximum access time) will keep running during all restarts.
• A robot must restart if bot does not start after pressing the Start Button for 30 Seconds, the bot is touched by a human without the consent of the referee, the bot moves out of the arena or the referee orders it to restart.
