Prenatal checkup is important for safety childbirth. However, now the problem of doctor shortage and hospital shortage is serious and pregnant have to wait long time for checkup. So, we developed ultrasonic diagnosis robot and proposed a new diagnosis approach using laminagraphy which is used in CT or MRI. Laminagraphy made it easy to control the degree and position, so the size of robot becomes smaller and feature becomes simpler than usual. We made experiment to check whether the robot could adapt to the shape of pregnant abdominal and determined the adjustment for 30th week of pregnancy.
