Disclosed is an electronic device including a robot arm configured to include at least one coupling portion configured to be coupled to a force sensor to which a specified object is attached, at least one actuator configured to drive the robot arm such that a position of the at least one coupling portion is changed, and a processor electrically connected to the actuator, wherein the processor is configured to: receive a first measurement value of the force sensor due to a weight of the specified object with respect to a first position of the at least one coupling portion, receive a second measurement value of the force sensor due to the weight of the specified object with respect to a second position of the at least one coupling portion, receive a third measurement value of the force sensor due to the weight of the specified object with respect to a third position of the at least one coupling portion, and estimate a relationship between a first coordinate system relative to the at least one coupling portion and a second coordinate system relative to the force sensor based at least on at least the first measurement value, the second measurement value, and the third measurement value to calculate a magnitude of an external force acting on the specified object.
