### In practical terms, how close is the accuracy of camera-based visual odometry/SLAM methods to lidar-based methods for autonomous car navigation?

Benedict Evans, a general partner at Andreessen Horowitz, claims that “almost all autonomy” projects are using lidar for SLAM, and that not all of them use HD maps. An MIT group is testing self-...

### Wait simulation time in a non realtime ROS simulation en python

I want to control a quadrotor with a Python script and run the simulation as fast as my laptop can, not only in real time. I've modified my world and now the simulation runs with 7-10 real time factor....
