Need help for project of using a raspberry for a robotic project with optical character recognition

So the project is to create a robot that can navigate through a maze, with symbols like letters or colored squares on the walls that indicates actions for the robot to do. I need 2 cameras for this, one at the right and the other at the left, but I don't know how to do letter recognition with 2 camera on the same raspberry at the same time. I even never used a raspberry before so I don't know if it is doable. It would be nice if the raspberry can handle the movement of the robot, the 2 cameras and 2 other sensors like a lidar and a IR sensor.
