Hi all,
 
I'm totally new to robotics so please pardon me for my mild understanding.
 
I'm researching on a project that will allow different people from around the world to control different robots.
The users would be controlling the robot on a web browser with its' camera view.
All these robots is restrict within the same area, controlled by wi-fi or radio.
There's a few ending points, so at the end of the controlled period, the system would need to know which ending point the robot is at.
 
A example would be a maze with different entrance & exits, all the robots will be controlled by different users to solve the maze.
 
From reading around documents and forums, it's state that a single robot can be setup to allow remote control with it's camera view. Is it possible with multiple robots within the same area?
Could the system detect the end point of the robot? To make it easier, I could add things such as QR code or a color/number board to have the camera face it in the end point. Would this help in making things simpler?
 
Would appreciate greatly for any guides and pointers to making my research fruitful.
 
Thanks a lot for reading.
