Most robotic industries use safety mats inside the physical barrier for safety purposes. I know there are commercial ones that you can buy, but I was wondering can we design a safety mat in such a way that it can find -for instance-the distance from an obstacle to a robot depending on a grid map? Lets say if I have the workspace around the robot to be 5*5 m^2, we divide this area into cylinders and depending on the location of the cylinder on the grid map, the robot would behave differently, slow down or shut off. What are the requirement for such a mat? power supplies? and I want it to be synced digitally to a computer via a USB.
