Washington State is set to welcome autonomous delivery robots to its streets becoming the eight American state to do so. The bill allowing the delivery robots to cruise city streets was signed last month by the state's governor Jay Inslee.
Fans of the delivery system say the six-wheeled robots help reduce pollution and traffic congestion thanks to their silent electric motors. The delivery bots may also help give local business an edge over big corporations like Amazon – allowing the local companies to deliver quickly and affordably without owning serious delivery infrastructure.
