Hi,
I'm working on a project and I need to tell the distance between two different sensors, at different angles. I'm going to have a home point for the robot to come back to and charge and i want to know the distance between the home point and the robot. I don't need it to map where the robot is just the distance between them.
I was looking into using ultrasonic sensors but they aren't angular so i looked at some time of flight sensors (ToF) but I couldn't find and i wanted to use.
