hi vivek
kindly post your arena details.. or picture..
Hi Vivek,
They are a number of ways to identify and avoid obstacles. It depends on the type of obstacles being used in the competition. Same is the case with finding victims. As Aamir as already mentioned in the above post you need to post more information regarding obstacles and victims.
thanks,
Actually im trying to buid a robot to participate in the robotics contest held at NIT Trichy.....

The arena will have 3 parallel tracks which are indicated by the black lines of width 3 cm on a white background. The distance between any two adjacent tracks will be 32 cm. Obstacles will be placed on each track. The bot has to navigate to the empty parking slot and indicate the completion of the task. Before entering the parking zone, the bot has to indicate the reach of checkpoint. At the checkpoint, 5x5 array of IR-LED’s will be placed at the right side of each track. The obstacle will be a white colour wooden block of dimensions 5 cm x 5 cm x 10 cm. The track may have sharp turns. There are parking slots available at one end of the arena. At any point of time, only one parking slot is empty. The filled in parking slot will be a space of 30cm x 30cm x 20cm 3-walled box as shown below. The same can be used for signaling the completion of task.

Hi... guys
I have done my hardware and circuit part... can some one help me with hardware and circuit to detect and avoid the obstacle... Im running out of time.... plz reply....
hey guys
kindly Check the c program that you shown in the page http://www.botskool.com/tutorials/electronics/8051/line-follower
and the files that you have for downloading at http://www.botskool.com/downloads/electronics/linefollower/linefollower.c
you have missed the following line in the file to be downloaded
P0_0=1; /*Enable pin of the left half of the H-bridge*/
P0_4=1; /*Enable pin of the right half of the H-bridge*/
Update it
