Through the analysis of the research status and application characteristics of the pipeline robot, a design of pipeline and slot multi-function robot is presented. The robot adopts pneumatic power systems and peristaltic walk way. The robot can move not only in reducing pipe to clean or detect, but also between the slot to rescue or transfer goods according to computer instructions. The system is operated by slave control unit and controlled by PC through an auxiliary rope, so the robot has advantages about real-time detection of the work state, strong driving force, easy maintenance and fault recovery, low cost and so on.

Hospital environmental Design involves many subjects such as architecture, psychology and praxiology etc. Artworks in hospital broadly improve the environment for patients, staff and visitors.
