Dive Brief: Estonian technology firm Cleveron, which specializes in last-mile parcel lockers and robots, unveiled on Wednesday a driverless, semi-autonomous delivery vehicle. Roughly half the size of a sedan, the delivery robot, called the Cleveron 701, can carry up to 500 pounds and travel within a 30-minute range of the warehouse or store at a maximum speed of 30 miles per hour. Teleoperators will be able to remotely supervise up to 10 vehicles at a time as they traverse low-traffic areas and roads. Cleveron’s announcement of the driverless vehicles comes at a time when grocers are increasingly testing robots for grocery delivery. Dive Insight:
