Achieving high-precision laparoscopic manipulation through adaptive force control

In this paper, we present a new solution to laparoscopic manipulation based on forcefeedback control. This method allows us to both explicitely control the forces applied to the patient through the trocar and to precisely control the position of the surgical instrument. It does not require any geometrical model of the operative environment nor any fine robot base placement prior to the instrument insertion. Different adaptive control strategies involving different kinds of sensory equipments are proposed. These strategies are experimentally validated on a laboratory apparatus. An experiment is also presented where a laparoscope held by the robot's arm tracks a target through visual servoing.

Acquisition of multi-modal expression of slip through pick-up experiences

To realize adaptive and robust manipulation, a robot should have several sensing modalities and coordinate their outputs to achieve the given task based on underlying constraints in the real environment. This paper discusses acquisition of multi-modal expression of slip consisting of vibration, pressure and vision sensations through pick-up experiences. A sensor network is proposed to acquire the expression, whose learning ability is demonstrated by a real experiment. The applicability of the learned network is also demonstrated by experiments to realize robust and adaptive picking.

Multi-Sensor-Based Control Strategy for Initiating and Maintaining Interaction Between a Robot and a Human

This paper presents a multi-sensor-based control strategy allowing a mobile robot to safely navigate with respect to a given human being. Two sensors are embedded in our robot: a vision system that is able to detect and track the person of interest, and a RFID antennas belt that can locate the tag worn by the latter. Thus, our control strategy will be built using image features (when the user is visible) and RFID information (when not). In the first case, a robust visual servoing control will be designed, while in the second case a suitable RFID controller will be proposed. Experimental results demonstrate the efficiency of the proposed control strategy.     

基于南方CASS的挖填方0界线自动追踪

南方测绘公司开发的南方CASS提供了多种土石方计算方法,但其追踪出来的挖填方0界线是用直线在方格内模拟的,与实际特征不符,故降低了土石方计算的精度．主要探讨如何在南方CASS中进行2次开发,实现挖填方0界线的自动追踪,并以实验为依托分析追踪结果的精确性．

Using simplified geometric models in skill-based manipulation

Dexterous manipulation plays an important role in working robots. Manipulator tasks such as assembly and disassembly can generally be divided into several motion primitives. We call these 'skills' and explain how most manipulator tasks can be composed of skill sequences. Skills are also used to compensate for errors both in the geometric model and in manipulator motions. There are dispensable data in the shapes, positions and orientations of objects when achieving skill motions in a task. Therefore, we can simplify geometric models by considering the dispensable data in a skill motion. We call such robust and simplified models 'false models'. This paper describes our definition of false models used in planning and visual sensing, and shows the effectiveness of our method using examples of tasks involving the manipulation of mechanical and electronic parts. Furthermore, we show the application of false models to objects of indefinite sizes and shapes using examples of the same tasks.
