A guide framework for positioning an ultrasonic transducer which emits a focused ultrasound to a target point in carrying out surgery to apply ultrasonic stimulation to a subject's brain, includes a body in a shape of a mask that is laid on the subject's face, and a positioning hole formed through an inner surface and an outer surface of the mask body, the positioning hole into which the ultrasonic transducer is inserted, wherein the inner surface of the mask body is formed to conform a facial contour of the subject, and when the guide framework is laid on the subject's face and the ultrasonic transducer is disposed at the positioning hole, the position of the target point is naturally disposed at a preset stimulation site of the brain. An ultrasonic stimulation device includes an ultrasonic transducer and the guide framework for positioning the ultrasonic transducer.

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.

Eyeball device for use in robots

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.
