This paper presents the result of the study on handover movement informing a receiver of the weight load as an example of the informative motion of a human-coexistence type robot (human-friendly robot). Movement of human body when performing handover task to a person was measured and analyzed first, and the features of variance of movement depending on the weight load were clarified. Then, the questionnaire survey was carried out to verify whether people could read out the difference in weight load from the variance of movement, in which the movement was reproduced using a simulator. It may be said that a receiver can judge whether a package is heavy or not, although it is difficult to estimate the exact weight load. Accordingly, if the variance of the noted points is included in the design of the handover movement of a humanoid robot, people as a receiver will be able to estimate the weight load to make easy to receive a package safely and certainly.
