+Problem Statement
To make an autonomous guided vehicle which can navigate on a road, stopping at zebra-crossing, following traffic lights and reaching an end point.
+Arena Specification
Road
-
Black tar surface.
-
The average width of the road would be 5 m.
-
Non-continuous white divider lines along the length of the road .
-
The length of a divider line would be 1.46m and distance between two consecutive white divider lines would be 3m with a tolerance of 20%.
-
The road shall have no explicit limiters on either side.
-
The road has both straight and curved sections.
Zebra Crossing
A single white line across the width of the road.
It will be located at 2 m from the base of the traffic light.
The dimensions of the white line in Zebra Crossing shall be notified soon.
Traffic lights
-
Standard green and red lights with the following interpretations : RED-STOP and GREEN-MOVE.
-
The lights shall be circular at a height of 2m from the ground level.
-
The box containing the traffic lights will be in horizontal orientation along the width of the road.The pole mounting the traffic lights can be on either side of the road.
-
The light source will be present on the extreme end of the box containing the traffic light,the end which is closer to the center of the road.
The diameter of the traffic light colors and their orientation in a rectangular block shall be notified shortly.

The following pictures are a SAMPLE of the traffic light, and are not the final arena pictures. They are to be used for testing your image processing. The final traffic pole and light arrangement will be uploaded just before the event.
The following things to be noted are :
1. The picture was taken at 4.00 P.M when it was sunny. The pictures appear dark, because to identify the traffic light, exposure of the camera was reduced. Please use this camera mode from your webcams to help you.
2. The traffic poles arent present in this picture

+Robot Specification
- The dimensions of the bot cannot exceed 1.5m x 1.5m x 1.5m.
- The bot must be autonomous and must not have any manual intervention during its run.
- Wired communication between bot and Processor is allowed .
- The bot should have provision for a button to stop the bot.
- Mounting of a laptop or any kind of hardware on the bot is allowed. You may also choose to carry the laptop along with you in your hand during the event.
- The robot is allowed to have external light sources on board, e.g an on board flashlight or headlight. However the flashlight cannot be toggled, (i.e shut on and off) manually during the run.
- Bot should be able to operate under all conditons of weather.
- Any type of sensor e.g camera is allowed for the robot.
- Note: A power supply of 220V would be provided by the ROBOTIX team.However keep in mind that it poses limitations on speed and flexibility of your robot. A wire of large length (approx 50 m) is required by participants to cover the track effectively. The participants are requested to bring their own wire if they wish to use the power supply provided by us. However, you may also choose to use your own power supply.
+Event Rules
Rules:
- The bot will start at a start line indicated by a continuous white line across the width of the road.
- The starting signal will be given by a traffic light turning green.
- The bot has to stop before the zebra crossing if the corresponding traffic light is red.It has to wait there till the traffic light turns green.
- If the bot goes off the road, a penalty would be imposed on the bot.
- The bot has to go past the finish line after which the participant has to stop it manually. The finish line will be denoted by flags kept only for scoring done by the event organizer.
Natural Lighting Conditions:
- The event will take place between 9 am to 5 pm. Any lighting condition that will occur during this time is a valid lighting condition, even if the weather is cloudy and overcast.
- The surroundings are outdoors with trees, and buildings. Pictures of the area will be put up soon.
- The event will continue even if a light drizzle is falling. In case of a heavy rain, the event would be postponed.
Calibration:
- Participants will be given 45 min of calibration time.
- During calibration, a team is free to place the robot on any part of the arena.
- Robot cannot be allowed to run on the track during this time.
- At the request of a team during calibration time, any light of the traffic signals will be switched on.
Restarts, Penalties and Scoring:
- Maximum of 3 restarts is allowed.
- Penalties are imposed for going out of the road and for not stopping before the zebra crossing on a RED Traffic Signal.
+Scoring Rules
- There would be 10 checkpoints between start and finish, so a bot gets some fixed points for every checkpoint crossed.
- Checkpoints would only be for evaluation purpose and not for the bot.
score = 1500+200*a - 4*T(in seconds) - 200*b - 300*c + bonus + points for algorithm
where
a is the no. of checkpoints successfully crossed
b is the no. of Traffic lights jumped
c is the no. of restarts given for going off the road
bonus of 500 points for reaching the end point.
- points would be provided for algorithm on a scale of 500.
- Time would be stopped when the the bot stops at the zebra crossing at a RED traffic signal and would be restarted when the traffic light turns green or the bot crosses zebra crossing (which ever is earlier)
- In case the bot crosses the zebra crossing when the traffic signal is still red, it is considered a jump of the signal.
- A bot does not have to worry about the change in signal once it has crossed the zebra crossing.
