Abstract: A robot arm that can be suitably used in aerial vehicles and an unmanned aerial vehicle equipped with the robot arm. The robot arm includes: an arm unit includes a plurality of joints; arm controlling means for controlling driving of the joints; and a displacement detector configured to detect a change of a position and inclination of the arm unit. The arm unit has a base end connected to the aerial vehicle. At least a leading end of the arm unit is exposed to an outside of the aerial vehicle. When the displacement detector has detected a position error that is an unexpected change of the position or inclination of the arm unit, the arm unit controlling means is configured to cause the joints to absorb the position error so as to prevent the position error from being transmitted to a side of the leading end of the arm unit.
