Current MATLAB differential mobile robot in Robotics toolbox works so slow in a big scale map. I would like to create my own robot as a particle without controller to perform desired task such as following the desired weight points in the grid map.
you can develop a datasets of of 1000x1000 grid and save in matlab and test this model sets in Matlab Simulink . in your robots you can connect your robot using usb cable to attach with matlab.
I figured out the problem. I implemented a particle mobile robot which has a dimension, speed and heading angle. Robot's new position is related to current position, robot speed and current direction as it shows below.
