Because of the nature of human biology with unmatched by some machine Can therefore make use of the natural world in recent years, exercise behavior and biology of certain machine Robot can carry out the design, implementation of its flexible control by the robot The extensive attention of scholars. Have been many domestic universities and research institutes in the open Outreach of micro-bio-robot research. Shanghai Jiaotong University-based imitation Principles of Health study, using six sets of parallel planar four-bar linkage, micro DC Motor and the corresponding deceleration by twisting bodies developed biomimetic hexapod micro - Robot, size small, has good mobility. The long-robot 30mm, wide 40mm, high-20mm, weight 613 grams, its walking speed Tatsu To 3mm / s [2]. Shanghai University also conducted a number of micro-bionic robot Research work. 2 micro-robot problem facing developing (1) drive the miniaturization MEMS micro-drives are the most important parts, from the micro-robot Development, micro-drive technology plays a key role, and are computer Human levels of device marks, the development of low power consumption, simple structure, easy to micro - , The displacement output and power output of large, linear control performance, dynamic sound Should be quick new drive (high-performance piezoelectric components, high torque micro-Horse Tatsu) are the future research directions. (2) energy supply problem Lot of the implementing agencies through the power-driven, but micro - Mobile robot, the power supply wire will seriously affect the micro - The robot sports, especially in the relatively large curvature changes in the environment. Development trend of micro-robot should be of no cable, power, control signals to And test signal should be sent no cables, transmission. Micro-robot to really Is practical, and must be resolved without cable microwave energy and non-cable data transmission technology Surgery, while research and development of small-size high-capacity battery. (3) reliability and safety At present, many are being developed and the development of medical micro-robot is Treatment, the military, as well as the background for the use of nuclear power plants in these very important Applications, the work of robot reliability and safety are designers Must be considered a problem and asked the robot which can adapt to Environment, and have troubleshooting capacity [4]. (4) a new type of micro-mechanism design theory and finishing technology Conventional micro-robot and robot is not easy compared to the node On scaled-down structure, and its development up to a certain extent and micro-drives and precision Processing technology development are closely related. At the same time demands Designer at Machine Conformation design innovations in theory and come up with suitable micro-robot transfer Moving bodies and moving way. (5) a high degree of autonomy control system Micro-robot to complete specific operations, its own location and the environment Recognition are the key to the development of micro-vision system, improve micro-images Agency The rationale for speed, the use of neural networks and artificial intelligence and other advanced technology to solution Summary of the high degree of autonomy control system problem is finally a practical implementation of the customs Button. 3 Conclusion Micro-robot is still in the laboratory theoretical exploration period, from the practical Have a considerable distance. There are many key technologies have not been Solutions Summary, the resolution of these issues at the same time the process will lead to lot of related disciplines Development. Only when these issues resolved, the micro-robot in real Could there be of use. We have to dare to innovate, to seize the forefront of Issues of micro-robot technology will be applied to national economic construction and development of video Ring for larger areas.
