Military robots are a) very scary and b) absurdly complex.
Bomb disposal robots can however save lives but their cost and technical sophistication makes it increasingly unattractive to leave damaged machines in the hands of an enemy force.
Today’s invention is a bomb disposal robot containing a UAV that ejects itself and flies home if the armoured, but technically rudimentary, outer vehicle is disabled.
The UAV ‘brain’ contains all the costly, classified control technology etc and thus avoids this being destroyed or captured.
This approach limits the need to apply huge amounts of armour, since the sensor unit can continuously assess the likelihood of forthcoming terminal damage to the outer vehicle.
