Amazon's delivery drones faced significant operational failures, crashing twice due to erroneous readings from their lidar sensors. The drones' software mistakenly believed they had landed, prompting the power shutdown of the propellers. This incident occurred after Amazon eliminated backup sensors that could have prevented the crashes. A software update further complicated the situation by making the lidar sensors more susceptible to inaccuracies in rainy conditions. While Amazon disputes the connection between sensor removal and the crashes, the NTSB documents indicate the situation could have been avoidable.
Amazon's decision to remove crucial backup sensors from their delivery drones led to two crashes, revealing lapses in safety and software reliability.
Documents from the NTSB indicate that bad readings from lidar sensors caused the drones to mistakenly think they had landed, shutting off propellers mid-air.
