To build a fully autonomous robot capable of following two parallel white tracks against a black background and report the errors (if any) in the laying down of the tracks.The errors can be of two kinds:

1. The width of the track (i.e. the distance between the two white lines) is less than or more than the correct width of track.
2. One of the tracks (i.e. one of the two white lines) is broken.

Note that both errors will not happen simultaneously.

1. There will be 3 arenas of width 2m X 2m.
2. The tracks will be white in colour and their length will lie between 2.0 to 4.0 meters.
3. The shape of the tracks will be random with no turn more than 90 degrees.
4. Each white track will be 2cm(with a maximum error of 0.25 cm) in width and the correct width of the track will be 5cm.
5. The width of the track will be the distance between the inner ends of the two tracks.
6. The end of the track will be arbitrary (i.e. the end of track will have no special condition attached to it, instead it will be a simple discontinuation of the two lines.
7. The arena base will be made of plywood painted black with blackboard paint. The tracks will be made of standard white chart paper.
8. The arena will be having standard classroom illumination. Any extra illumination has to be arranged by the participants themselves.
9. We will be providing only a desktop computer (P-IV, 256 MB ram,windows XP ). No programmers will be supplied. Participants will have to bring their own programmers ,cables and softwares.
10. The participant has to submit the code before the commencement of first round . The microcontroller will be sealed. He/She is not allowed to change the code or the microcontroller once submitted . In case of damge to microcontroller , the submitted code will be provided to the participant .

1. The initial size of the robot should be restricted within 20cm X 20cm X 100cm (length X breadth X height).
2. The robot can exceed these dimensions once the event commences.
3. LEGO kit or other such similar kits or its spare parts are not allowed.
4. 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.

1. Each team can consist of maximum of 4 members.
2. At a time only one robot will be allowed inside the arena.
3. At the start of the event the robot will be placed at one of the extreme ends of the track. Its initial orientation is at participants’ discretion.
4. The robot has to autonomously follow the track and reach the other extreme end of the track and stop.
5. The errors will have to be reported at the time they occur on the track. The error will be displayed using two LED display. The robot must glow a red LED to report an error in width of the track and a blue LED to report a broken track.
6. An error in the width of the track will only be considered if the width of the track is less than 4 cm or more than 6 cm.
7. The width of the track will be between 2.5cm to 8cm throughout the track.
8. The length of the broken track will be greater than 1cm and less than 3cm throughout the track.
9. No error(error in width or broken track) will occur at the bends.
10. In case the robot completely loses the trail of the track or it encounters some internal problem, the team has an option of restarting their robot. A maximum of 2 restarts are allowed.
11. Only power supply line will be allowed to the robot. These cords/cables should remain slack throughout the event.
12. No kind of external control will be allowed.
13. Only the power source will be allowed outside the robot. All other circuitry and sensory equipment should be placed on the robot adhering to the ROBOT SPECIFICATIONS listed above.
14. The participants will be provided with 220volts 50Hz standard AC supply. Participants will have to themselves arrange for any other power supply required for their robot.
15. The arena will be having standard classroom illumination. Any extra illumination will have to be provided by the participants.
16. The robot must stop at each error for at least 5 seconds and glow the corresponding LED. This time will not be counted in the total time taken by the robot.

1. Each robot will be given a run on each of the arena.
2. Score on each arena = 5 x (no. of correct error in width reported) + 3 x (no. of correct broken tracks reported) – 2 x (no. of false error reports) – 1 x (time taken in seconds/10).
3. Total score = sum of individual scores of each arena.
4. The winner is the team with maximum score.
5. Maximum 10 minutes will be given to each team to complete an arena.

1. Each team can consist of a maximum of 4 members.
2. The team members can be from different institutes or colleges.
3. The right spirit of participation is expected form the participants.
4. The decision of the ROBOTIX team will be final and binding.
