"Methodologies, systems, and computer-readable media are provided for in-field authentication of autonomous electronic devices. A first mobile autonomous electronic device wirelessly communicates with a second mobile autonomous electronic device and receives a set of identification information associated with the second mobile autonomous electronic device. The first electronic device autonomously travels to a specified location and transmits a first authentication signal to the second electronic device upon arrival at the specified location. The second electronic device confirms the identity of the first electronic device based on the first authentication signal and transmits a second authentication signal to the first electronic device. Once the first electronic device has confirmed that the identity of the second electronic device corresponds to an expected identity, the first electronic device transfers the object to the second electronic device."
