Abstract: In a full duplex data transfer method system, a first transceiver and a second transceiver are configured to transmit and receive data packets. At the first transceiver, a status indicator is added to each data packet in a set of data packets and the status indicator of each data packet is initially set to not transmitted. A list of all data packets having a status indicator set to not transmitted is maintained. All data packets of the set are transmitted from the first transceiver to the second transceiver while the first transceiver receives transmissions from the second transceiver. At the second transceiver, all data packets received are saved and an indication regarding the data packets received are transmitted back to the first transceiver. At the first transceiver, the status indicator of all data packets in the list received by the second transceiver are set to received.

Abstract: A battery powered remotely controlled robot is equipped with a drive subsystem for ground travel, a flight subsystem for flight operations, and an obstacle detection subsystem. The robot is configured so that during a mission the drive subsystem is energized to maneuver the robot on the ground for a majority of the mission. The robot is further configured so that upon detection of an obstacle, the flight subsystem is energized to traverse the obstacle. The fight subsystem is energized only to traverse obstacles thus saving battery power and increasing the mission time.
