To build a fully autonomous robot capable of traversing some geometrical shapes and an arbitrary path, and to display the path length.

•  There will be 5 arenas, each 1.5m X 1.5m.

•  Each arena will have a distinct shape outlined on it. viz; Circle, Pentagon, Square, Triangle and one Irregular shape.

•  The outlined shapes will be white in color and their length will lie between 2.0 to 4.0 metres.(06 Jan 2006)

•  The lines will be 2 cm in width. At the corners, the effective width would be upto a maximum of 3.5 cm

•  Each outline will have a small discontinuity, to mark the beginning and end of the shape.

•  The arena base will be made of plywood painted black with blackboard paint. The shapes will be made of standard white chart paper.

•  On the irregular shaped arena, none of the turning angle will be more than 90 degrees.

•  The arena will be having a standard classroom illumination. Any extra illumination has to be arranged by the participants themselves.

•  Taking into consideration the problem faced by the registered teams in distinguishing between the conditions: (1) Bot deviating from the line and (2) Bot reaching end of line; the following modifications are being made. The team has an option of choosing any one of the following modes for all the arenas:(16th Jan 2006)

1. A wooden solid wall (white in color) of 25 cms by 25 cms dimensions will be placed at the end of the line.
   The above modification can help the robot to detect the end of line with a bump or obstruction sensor. An allowance of 5 cms will be made for the length of the robot. The initial size of the robot should be restricted within 25 cm * 20 cm * 100 cm (length * breadth * height) for this case only.
2. A white patch of 25 cm*15 cm (length * width) will be placed at the end of the line.
   This will enable the bot to detect the end of line if all its line tracking sensors go high on detecting the white patch.
   No other modification in terms of size of the bot will be allowed in this case.
3. The team can choose not to opt for any of the above options and can continue to operate on the originally specified arena.

An arena of an irregular shape

•  The initial size of the robot should be restricted within 20cm * 20cm * 100cm (length * breadth * height)

•  The robot can exceed these dimensions once the event commences.

•  LEGO kit or other such similar kits and its spare parts are not allowed.

•  Readymade gearboxes can be used but no other part of the robot should contain any readymade components . Simple car bases with no extra features may be used.

•  Each team will consist of maximum of 4 members.

•  At a time only one bot will be allowed inside the arena.

•  At the start of the event, the bot will be placed on either one of the sides of the discontinuity of the outlined shape. Its initial orientation is at the participants discretion.

•  The bot has to autonomously follow the outlined shape and reach the other side of the discontinuity and stop.

•  After stopping, it has to display the amount of distance traveled in a specified format as given below below for a minimum of 10 seconds. This time will not be considered while measuring the net time taken to traverse the outline.

•  The net distance traveled will be displayed in binary format using a LED array of eight. The LSB(Least Significant Bit) bit will be displayed using a Blue led and the other bits using a Red led.

•  Each binary unit will correspond to 2cm distance traversed by the bot.(06 Jan 2006)

•  In case the bot deviates from the outlined shape on the arena or it encounters some internal problem, the team has an option of restarting their robots. A maximum of 2 restarts are allowed.

•  Only power supply line will be allowed to the bot. These cords/cables should remain slack throughout the event.

•  No kind of external control will be allowed.

•  Only the power source will be allowed outside the bot. All other circuitry and sensory equipment should be placed on the bot adhering to the Bot Specifications listed above.

•  The participants will be provided with 220 Volt 50 Hz standard AC supply. Participants will have to themselves arrange for any other power supply required for their bot.

•  The arena will be having a standard classroom illumination. Any extra illumination will have to be provided by the participant.

•  Participants are required to submit a brief write up on their bot (not exceeding 1500 words). It should mention any special algorithm, circuitry or any other unique feature which has been implemented on the bot. The Best Design Awards will be decided on the basis of these write ups. Participants must submit a hard copy of the write up at the beginning of the competition.

• Score on each arena = Arena Factor * (10 * absolute (Error in distance in cms)) + 1 * (Time taken in seconds)

• Arena factors:
circle = 1, regular pentagon = 1.2 , square = 2, triangle = 2.5, irregular shape = 3

•  Net score = Sum of scores on each arena.

•  The winner is the team with the minimum score.

•  No penalty will be awarded for deviating from the line, but if the robot deviates from the line, it should return back to the line whithin 5 cms from the point of deviation. In any other case, the team would be disqualified.

•  Maximum of 10 minutes will be given to each team to complete the objective on each arena.

•  In case of any failure of the bot , the team is allowed to ask for a restart subject to the above stated rules..

•  The team will be allowed to continue to the next arena only if the error in distance calculated on the previous arena lies within 20% of the net distance.

•  No predefined length should be fed into the robot at any stage, failing to which could lead to immediate disqualification.

•  Each team can consist of a maximum of 4 members.

•  The team members can be from different institutes or colleges.

•  The right spirit of participation is expected form the participants.

•  The decision of the ROBOTIX team will be final and binding.

•  1st Prize –	Rs. 10,000
•  2nd Prize –	Rs. 7,000
•  3rd Prize –	Rs. 5,000
•  Best Design –	Rs. 3,000
