iRRT is a simple java program for simulating the widely used robotics path planning algorithm known as Rapidly-exploring Random Tree or RRT. The algorithm was originally developed by Steven M. LaValle and James Kuffner. iRRT also implements a variant of RRT called RRT*, an algorithm developed by Sertac Karaman and Emilio Frazzoli. Another variant which has been named RRT+ is a by-product of the development of this tool.

To run the simulator download iRRT.

Following are some videos of iRRT.

  1. […] the path segments around that point and the closest tree edges. Interested readers can check out this simulator comparing RRT and RRT*. The longer one runs RRT*, the better the obtained path will be. This is a […]

  2. […] ir refinando poco a poco las trayectorias que pasan cerca de dicha zona (quien esté interesado, aquí se puede encontrar un simulador que compara RRT con RRT*). Cuanto más tiempo se le deje para […]
