Abstract: Model driven architecture (MDA) is an architecture specification of software development proposed by OMG in July 2001. MDA holds that the best way of software development is to enhance the level of abstraction of the system, isolate the design and implementation of the system, and separate the business conduct, so as to overcome the difficulties caused by the complexity of software. This paper presents the basic concept and core technology, and gives the software development process based on MDA.

Abstract: Exoskeleton suit is a kind of human-machine robot, which combines the human’s intelligence with the power of mechanism. NES-3 is a pure motor actuated power assist exoskeleton suit. A special mechanical design using backstay cable for transmission system is proposed in the paper. The design can depart the motor from its control object which make the leg of NES-3 is very light and reduces the power cosumption of the operator. An extend gas spring is used in the hip joint to conquer the rotation torque of the load. A compress gas spring is used in the knee joint which can make the knee joint bend naturally. The two gas springs also can save the operator’s power cosumption. Detailed mechanical design is showed in the paper and achieves its design objecttive.
