my research project is "Particle Swarm Optimization Based Dynamic Target Tracking Military Robots with Lego Mindstorm NXT 2.0 (Hardware)"
The main hurdle which i am facing right now in my research is as under"
1st. How to find unknown Xid (current position) of the robot in unknown environment , after finding current position i can easily apply PSO on my research project. Because in formula only three parameters are needed, xid, pbest and gbest. I can easily calculate pbest and gbest but the problem is with current position of robot in each iteration. How I calculate this and put in formula in every iteration in unknown position of unknown environment.
2nd. the color sensor which comes with the package of "Lego mindstorm robotic kit" can detect or identify colors in the range 1 to 2 inch. which is not enough for identifying any object or color. as u we know target or any particle is placed at least at a distance of 10-20 inches.
kindly guide me which technique i should adopt for calculating the current position of robot used in every iteration and second how i identify any object or target placed at a greater distances.
please suggets a proper color sensor who fulfill my needs and also compatible with lego mindstorm kit. in case if there is no any sensor who can sense in that range, plx suggest another technique which can detect or identify different objects which are at a distance ...................................... thanx in advance
