To provide an automatic machine that smoothly and simultaneously performs reactions including action, facial expression, and/or voice.

The automatic machine includes N output units, a storage unit 16, and a control unit 18. The control unit 18 is electrically connected to the output units and storage unit 16. The storage unit 16 stores a first reaction pattern 160 that corresponds to a first command. The first reaction pattern 160 includes a header and N reaction modes, and each of the reaction modes corresponds to one of the output units. Each of the reaction modes includes M reaction frames. The control unit 18 receives the first command, examines the first reaction pattern 160 in the storage unit 16 according to the first command, and selectively controls at least one of the output units to perform the reaction frames correspondingly according to the header and reaction modes.
