RRT Smart Algorithm for a finite volume robot:

This is an RRT implementation for a finite volume robot with kinodynamic constraints.

Rapidly-Exploring Random Tree

Instructions:

  • Run the file RunMe.m in Matlab (R2009b+)

  • Make sure the files: (a). CollisionFree (b). H5_robot.txt (c). Near (d). Nearest (e). ObstacleFree (f). RRTs (g). Steer (h). Steer2 (i). circle (j). circleExtrude (k) confun (l) mat_file_cal (Not required by RunMe; Needed for CSV file generation) (m) plotObstacle (n) plotObstacleExtrude (o) robot are in the same folder.

  • mat_file_cal creates CSV files which contains the time, position (x,y), theta, velocity, omega, acceleration and gamma (steer acc) in the respective order.

Input Arguments:

  • xdim, ydim : Size of the grid
  • Start Node: start_node [x y]
  • Target: goal [x y]
  • radius: Radius of the End Goal region
  • r: radius of the obstacles
  • Epsilon: Minimum Step size for the RRT
  • Change the input data here

Sample Outputs

Sample CSV Files

Requirements

  • Matlab R2009b or later.

Notes

  • Tested on MATLAB R2016b, Arch Linux 2017.03.01, Kernel: 4.9.11
