Lancaster is getting ready for the arrival of robots. City Council will give a first reading to a proposed ordinance outlining rules for automated personal delivery devices next Tuesday. Those are ground-based devices that can operate autonomously or remotely and are made to transport items like food, paperwork or medicine. The devices are now legal in Pennsylvania if they get authorization from the Pennsylvania Department of Transportation. But if the city ordinance passes later this month, companies like Amazon and FedEx âwhich are testing the devices in a handful of markets across the country â would need specific route approval from the city before sending any rolling down Lancaster streets or sidewalks.
