We developed a novel catheter operating system with an integrated force sensor for medical applications which included a highly precise master-slave remote control system. This paper explains the system design and control system in detail. As part of our research, we designed a micro force sensor and included it in the system to ensure safe operation in intravascular neurosurgery applications. We performed operation simulation experiments and analyzed the operating errors. The experimental results indicated that the proposed force sensor-based catheter operating system works well and can be controlled remotely, and the force feedback can effectively improve operability at an aneurysm.

Recent years, Unmanned Aerial Vehicle (UAV) has gained great attention and importance both in civil and military applications all over the world. Ground Monitoring and Control System (GMCS) is an important part of the entire unmanned helicopter system. As UAV develops rapidly, the functions and tasks are becoming increasingly complex, and the ground control station needs to collect more data. In addition, establishing a real-time and reliable communication system has become an important part of the control system of UAVs. The μC/OS-II operating system has the characteristics of modular application which can be used for multiple task operations, and can satisfy the requirement of real time system very well. And the system was successfully applicable to practical UAV fighter and the setting up of The Ground Monitoring Station.

The remote control system platform and the main function modules are studied and analyzed based on Android operating system. The problem of image transmission of remote control on Android equipment is solved by means of the analysis and comparison of several methods of screenshots and image compression, such as ImageIO compression and JPEGEncoder compression. Finally, we got the conclusion that the transmission efficiency can be increased by the screenshots with robot class and JPEGEncoder compression.

Micro Force Sensor

Because of the micro/nano manipulation's complexity, the accurate feedback information of the micro interactive force acting on micro devices is quite important and necessary for micro/nano manipulation, especially the 2-D micro interactive force feedback information. At present, there are no reliable and accurate 2-D micro force sensors applied in micro/nano manipulation. To solve the above problem, a novel 2-D micro force sensor that can reliably measure force in the range of submicro Newton (μN) is designed and developed in this paper. Based on the model of 1-D micro force sensor designed by us, the model of this 2-D sensor is set up. To verify the model of the 2-D sensor, micromanipulation experiments are designed and realized. Experiment results show the submicro Newton resolution, and verify the validity of the 2-D sensor's model. The developed 2-D micro force sensor will contribute to promoting the complexity of micro/nano manipulation, and will facilitate to automate the micro/nano manipulation.

Central Control System

This paper deals with a system, which is subjected to very uncertain factors: human and environment. These independent uncertainties are dealt with explicitly on the framework of μ-synthesis. We also describe a controller design, which enables a robust force feedback without using a force sensor. The model of human dynamics, environments, and actuators are modeled associated with uncertainties described in the form of weighting functions. A controller is designed based on the μ-synthesis so that it maintains robust performance against uncertainties in both environment and human dynamics, which contributes to dexterous manipulation. The controller described here is implemented on the human power extender, which is worn by a human and amplifies the human’s physical strength, while the human’s intelligence remains as the central control system for manipulation. Experimental results conducted on the extender showed that the force estimation worked fine and the control system performed as desired.
