Arduino - Expert - Want To Make a Fully Functional Robot

I will expose the project and at the same time ask some questions that you would have to answer: I want to build something similar to a line robot, such as those made in the arduino robotics courses, however in this case the goal is not education, it will be a fully functional robot, with professional materials, so that it is running constantly in a commercial establishment. 1) We have already built a line guard, but in this case we want it to follow a certain route but without lines on the ground, what proposal do you have? (we will raise our own) 2) We are contemplating the possibility that the person in charge of the project works in both software and hadware, since there are low cost platormas that would allow replicas to be made so that the developer works with a material in his house and we have A replica of ours in ours. you could do it? There are even complex platforms that already have everything you need: - [login to view URL] - [login to view URL] - https://www.amazon.es/Seeed-Studios-RPlidar-Plataforma-Experimental/dp/B07P5H1HXJ/ref=sr_1_13?keywords=lidar&qid=1570959942&sr=8-13 3) All these platforms include a mapping and positioning system by LIDAR, could you work with it? This would be the system independently, without incorporating it into any other element: - [login to view URL] - [login to view URL] - [login to view URL] 4) Could you work with this system? Could you map the room with it and plan a route? If we want to work with this system and position it on an independent platform, one of this manufacturer could be used: - [login to view URL] It would be interesting if they answered these questions.
