MADISON, Wis. (AP) — A pair of state lawmakers tried to persuade a Senate committee Tuesday to approve a bill that would allow delivery robots to traverse Wisconsin sidewalks and crosswalks. The measure would limit the robots to operating only on sidewalks and in crosswalks, impose an 80-pound weight limit as well as a 10 mph speed limit and require operators to control or monitor the devices. The bill would prohibit the robots from traveling in roadways and allow local governments to ban them if they so desire.
