Boeing has carried out a military robot demonstration for the US Army in which robots were used for psychological warfare.

Boeing’s director for unmanned aircraft systems Vic Sweberg said the robots used a combination of hardware and software from five different contractors to carry out letter drops and disseminate information for people on the ground using unmanned vehicles.

Boeing showed off its new technology by doing a demonstration letter drop, combining audio announcements and taking video of the targeted area.

The infrared nightsight video of the target area was taken, propaganda announcements were played through speakers on the R-Gator and leaflets were dropped from the helicopter.

The demonstration shows that military robots have started learning the more tricky task of persuading people to comply with orders or give up simply by spreading information.
