Abstract: A robot includes a head, a shoulder, and a rotary structure. The head includes a housing and a fixing frame. Connection assemblies are disposed between the housing anti the fixing frame. Each of the connection assemblies has a fixing shaft fixedly connected to the fixing frame and a flange rotatably installed to the fixing shaft, and the flange is fixedly connected to the housing. The rotary structure includes an adapter rotatably connecting the fixing shaft about an axis of the fixing shaft and a drive source rotating the adapter. The adapter has an installation disc portion for connecting the shoulder and a drive portion for connecting the drive source.
