Abstract: Various embodiments of an eyeball device for use in robots are provided. In one embodiment, the eyeball device has an eyeball, a main part having a camera, a frame having first and second sections, first and second actuators, a first connecting member and a second connecting member. The first section is horizontally pivotally coupled to the main part relative to the main part, while the second section vertically pivotally supports the eyeball. The first and second actuators produce rotary motions. The first connecting member is coupled to the first section and the first actuator to connecting the rotary motion of the first actuator to the first section. The second connecting member is coupled to the eyeball and the second actuator to transmit the rotary motion of the second actuator to the eyeball. The eyeball horizontally pivots through the first connecting member and vertically pivots through the second connecting member.

Abstract: Various embodiments of a lip moving device for use in robots are provided. A lip moving device has first and second lip members. The first and second lip members are made from a flexible material. First and second driving parts apply torques to both ends of the first lip member, while third and fourth driving parts apply torques to both ends of the second lip member. The first and third driving parts are mounted in a first frame. The second and fourth driving parts are mounted in a second frame. The first and second frames are pivotally coupled to a supporting part. An adjusting part pivots the first and second frames relative to the supporting part to adjust a distance between the first and second frames.
