Load different memory

Projects General Guidance
1

Hello all,
I need some help in designing some part of my project related to memory.

so i'm building a switch/keypad controlled robot, which moves from point a to b. this part is fine i can build.
Using arduino mega and servo motors.

Haven't started yet but i do have basic idea on what all i have to do and basic coding for robot to move.

description (example): robot is placed in a house with 3 rooms and hall, initially robot is in the hall and keypad has few buttons which will make robot go till the door of the three rooms,
now in a room, i ll have few more points which robot can go to, so using keypad i can select the points. okay so i will use RF rx and tx connected to keypad (remote location) and arduino.

the question is, i can store if few points are there in the house, but what i want to do is, when the robot goes near the door, it has to load the points to arduino of that room and then when it exits has to delete those points.

can i use bluetooth module? or nfc or anything?
does anyone have any idea how to do?

so for now once i load different memory to robot at each point, and test it.
then i can have additional features to my robot which can grab an object or press a switch or any other feature.

That sounds like an extremely ambitious project. To the question of needing to load a separate set of data for each room, I don't know where that data will come from or how much data there will be, but one option would be to store all the relevant data on an SD card and load in whichever subset is relevant to your current environment. I suppose your 'bot will have some way to know which set is relevant to it, for example by knowing that it is trying to enter a room with a specific ID so that it will need the data subset associated with that ID.
