We are actually using monocular computer vision to navigate in the sidewalks and in some robots LIDARS for collision avoidance, we are also testing with SLAM detection in the smartphone we have in our kiwibots. We have made a great progress in automation and self driving, also in network software for take control of the robot if we need it (last 3 minutes of every delivery we control the car to make sure we deliver in the correct address, also for crossing streets and crowded sidewalks. Still in a semiautonomous phase but really excited about the future, any feedback to improve our product?
