    Do robotic arms in a car plant operate mostly based on information provided by sensors? Like they aren`t thought to operate blindly, there is a process of camera/sensor based aiming/homing (if we talk about say a welding arm) on the region where work needs to be done.

      Depends on the application. There's a large variety of different position and control sensing methods.

        So basically it`s a two way process(sensors can stop/modify the process of state switching), it`s not just a blind switching of states that bears no relation to the changes in the outer world.

          No. It's the entire range between no sensing at all to switches to detect objects to vision systems to detect objects and positions of them, and everything in-between. There is no one sensing system to rule them all.

            One of the reasons why I`m asking is I remember seeing car plant footages from the 80`s displaying robotic arms working unassisted (by man) on car frames. Back in those days the sensor technologies were pretty much inexistent so lot`s of questions raising with regards to that kind of footage. From what you`re saying I get that initially it was 'touching' based.

              Those robots were programmed to repeat a fixed set of actions with very little sensor intervention. Move forward x inches, move left y inches, spot weld for z milliseconds, move back, and wait for the next car to arrive.
