BEHIND THE ENEMY LINES
Overview:
A leak from a highly reliable source hints us of a possible presence of nuclear
warheads in the enemy territory. The location is completely camouflaged and
almost invisible to the eyes of our satellite. After the assimilation of lot of
data, the approximate coordinates of the major targets were traced. It is also
feared that the base is full of landmines.
The Task:
The task can be divided into two main stages:
1. Locating the targets: You will be given an image, which will highlight
the targets. You will have to calculate the coordinates of the targets in this
image.
2. Destroying the targets: With the help of the overhead camera, travel to
the coordinates as in the image and destroy them. Avoid moving over the
landmines and laser maze.
NOTE:
The targets will be present only in the image and will not be
physically present in the arena.
The landmines and the laser maze will be present only in the
arena and WILL NOT be present in the image.
Image specifications:
(This is the image which would be given during the start of the play)
1. The image will be of jpeg/gif format.
2. The resolution of the image will be 320 x 240.
3. The background color of the image is white.
4. There are will be 5 colors present in the image and each color identifies
the target type. The following color will be present:
a. RED : Surveillance Room
b. GREEN : Power Substation
c. YELLOW : Nuclear Warhead Assemblage Room
d. PINK : Nuclear Warhead Storage Place
e. BLUE : Nuclear Warhead on Launch Pad
5. There will be one each of surveillance room, power substation, nuclear
warhead assemblage room and nuclear warhead on launch pad. There will be
multiple nuclear warhead storage places.
6. Every target is represented by 10 x 10 squares of the corresponding colors.
7. The colors in the image will be uniform, subjected to the tolerance of the
image format encoding.
Arena Specifications:
The arena will be a non-reflective surface on top of a wooden base.
An overhead USB camera with a 2 Mega Pixel resolution will be provided.
The drivers for the camera will be provided before the competition.
The position of the camera with respect to the arena will be fixed.
The background color of the arena will be brown.
The landmines will be present in the arena as blue colored circles of
diameter 7cm.
The arena will not contain any other color.
There would be a laser maze present on the upper half of the arena which on
solving reaches you to nuclear warhead on launch pad.
The laser maze would be made of lines of 4cm thickness and are colored in
blue.
The dimension of the arena will be 320cm x 240cm.
The dimensions of the laser maze will be 70cm x 240cm.
(For further clarity on laser maze refer figure)
NOTE:
You will not be permitted to use any other camera other than the
one provided by us.
Neither the camera nor the arena will be moved under any
circumstance.
There would not be any land mines in the laser maze.
Robot specifications:
1. The bots must be within the dimension of 25cm x 25cm.
2. The potential difference between any 2 points in the robot must not exceed
12V. However a tolerance of 2V will be considered due to battery
overcharge.
3. The robots are allowed to communicate with a computer outside the arena
either wired or wireless. In case of wired link the wire must be slack at every
instant of the trial and must come out from the highest point of the bot.
4. Use of on-board sensors/ camera is not allowed.
5. The robots must have an integrated buzzer for indication purposes.
6. Use of the following soft wares for image processing is allowed:
a) Open CV
b) VC++
c) Matlab
d) Scilab
NOTE:
In case you want to use any other software, you MUST first confirm with
the coordinators if the use of the software is permitted or not.
