This paper is concerned with formulating the design specification and making hyperbaric oxygen chamber for multi-users. HBOT(Hyperbaric Oxygen Therapy) is very effective remedy for increasing the concentration of melted oxygen in human and animal body. The melted oxygen supplies to each cell in body to recover the normal condition. This research reported the design specifications and mechanical test results of hyperbaric oxygen chamber made with polyurethane as well as computational analysis with CATIA program. These data can set the physical dimensions of practical HBOT equipment for multi-users and be used to produce the effective commercial model.

This paper is concerned with the designing and making power lifting wheelchair. This wheelchair is studied based on the mechanical and electrical engineering concepts and theories. The statics and dynamics are studied with moving and lifting motion. The power lifting wheelchair is compared with the previous model, the power standing wheelchair, in the sense of kinematics and kinetics. The main functions of these two models are to reach to the standing height of normal person and to move by electrical power. However the lifting mechanism gives more comfortable feeling to users when the chair reaches to the high position with sitting in chair. Without stretching the user’s leg, the X-truss mechanism is applied in this wheelchair. Also the wheelchair is controlled by the joystick attached on the arm rest. The real size model is made and investigated by the test drive. Finally, this power lifting wheelchair proves the possibility of commercial production.

This paper is concerned with the designing and making small unmanned aerial vehicle robot. In general, Unmanned Aerial Vehicle(UAV) is the aircraft without human pilot and then controlled by computer programs or person in Ground Control Center(GCC). The UAV can be used very widely and effectively in disasters situations, for example, exploration of fires in mountains and salvation of missing peoples in earthquakes. In these essential purposes of UAV, it is very demandable to design and make the commercial model nowadays. So this is the very practical and economical results in designing and making the small UAV robot. The main body of aerial vehicle is studied by inspection of aerodynmic concepts and made as commercial model. All electrical and computer-controlled systems are studied and selected to satisfy the desired functions and specifications of UAV. The results of experimental flights by the newly designed and assembled UAV robot in this paper show the possibilities and practicalities. Finally, the UAV robot of this research proves the possibility of field adaptations in real disastrous situations.
