Go-self high-field-gap rice variable manure spreader always uses high-field-gap special designed batholiths and manure spreading device, however, there exist some problems in its hydraulic drive system and rowing manure controlling unit, such as paddy field manure spreader in low field-gap, spreading manure quantity adjusting technology draggled, low work efficiency, etc. According to the manure spreader producing course and its structure parameters, AT89C51 singlechip is used as a core control element in the control system, controlling performance experiments of the manure spreader for spreading manure was made on ground and rice field. The results show that the performance of special designed control table achieved expecting require, and the control system meet the requirements.

In order to improve space positioning accuracy of the Agile Wrist consisting of a modified spherical parallel manipulator, which will influence the result of the Collisions experiment in a robotic mechanical testbed directly, this paper explores the motion control of Agile Wrist. Based on analysis an input - output (I/O) equation of spherical four-bar linkages for forward-displacement of spherical parallel robots, the inverse kinematics derivation is reported here to find the active-joint variables for each possible position and orientation (pose) of the mobile plate, as well as the singularity exist and defines what may be generalized as the workspace boundary. Meanwhile the kinematics simulation by using simulink S-Function combined with Q8 controller was carried out. The results showed that the Kinematics analysis and Control Design of Agile Wrist were correct. The modified spherical parallel manipulator can meet with the demands of Collisions experiment in the robotic mechanical testbed.

In our previous research we have made literature analysis and discovered possible mind map application areas. We have pointed out why currently developed software and methods are not adequate and why we are developing a new one. We have defined system architecture and functionality that our software would have. After that, we proceeded with text-mining algorithm development and testing after which we have concluded with our plans for further research. In this paper we will give basic notions about previously published article and present our custom developed software for automatic mind map generation. This software will be tested. Generated mind maps will be critically analyzed. The paper will be concluded with research summary and possible further research and software improvement.
