Question

If you use an open source SLAM software, which software you will select? Present your reasons.

Answer 1

SOLUTION :-

There is a open source SLAM software is the Cartographer, as in this tool is uses library in both 2D as well as 3D with the ROS support.

The SLAM algorithm used here combines several data from several sensors and then simultaneously compute the position of the sensor. This is actually used in designing floor plan.

* in the EKF SLAM the state vector is compromised of the current pose estimate and landmark estimates. Whereas, in FastSLAM uses no state vector like the EKF SLAM, but it loose small part.

* In EKF SLAM  uses all the densities that are involved in the calculation of the posterior and is modeled as Gaussians. In case of the FastSLAM, the problem is basically decomposed into K+1 sub-problems.
