Due to the technical difficulties related to the practical application of Lyapunov's 2nd or “direct” method in the adaptive control of nonlinear systems as an alternative approach the use of “Robust Fixed Point Transformations (RFPT)” were suggested on the basis of recent researches. Various application possibilities were revealed for the new controller and design for imprecisely and partially modeled...
This paper describes a dynamic transition motion from ladder climbing to brachiation for a multi-locomotion robot (MLR). In our previous works, the static transition motion from ladder climbing to barchiation has been developed. However, the motion is based on stable static model. It is difficult to realize the flexible and fast movement. To solve these problems, a new dynamic transition motion is...
This paper reports a novel and versatile hybrid microassembly technique that applies water mist on the surface of microparts to assist alignment of microchips. This technique combines the traditional robotic pick-and-place technique and self-assembly technique. Two different approaches are studied: 1) mist-last where a 200μm × 200μm × 70μm SU-8 chip is placed roughly on another chip of the same size...
In this paper, we demonstrate the usefulness of the micro-manipulation system with a robotic straw proposed by the authors for the microorganism isolation task. Isolating microorganism is one of the fundamental bio-manipulation tasks. This task has been conventionally achieved with a straw connected with a rubber tube. However, some skill is required by an operator for this isolation task, because...
This paper presents innovative driving method for the magnetically driven microtools (MMT) which is micrometer positioning accuracy by horizontally arranged permanent magnets. A piezoelectric ceramic is used to induce nanoscale vibration to the microfluidic chip to reduce the friction on the MMT. The enucleation process has been conducted by the dual arm MMTs. MMTs receive enough driving power supplied...
We are developing a Semi-Autonomous Remote Maintenance Robot for power distribution line maintenance tasks. The system is operated by task instructions; for examples, “Peeling electric cable cover”, “Remove the insulator” and so on. When the system receives a task instruction it measures the task object position; modifies the arm positions in the move commands; and then performs the task. In this...
We propose a non-invasive ultrasound theragnostic system that tracks movement in an affected area (kidney stones, in the present study) by irradiating the area with high-intensity focused ultrasound (HIFU). In the present paper, the concept behind a novel medical support system that integrates therapy and diagnostics (theragnostics) is illustrated. The required functions for the proposed system are...
This paper deals with an adaptive multi-robot task planning. When a desired goal state of the task environment is given, backward task planning from the goal state and forward search form the initial condition such as currently available robot and functions and displacement of objects etc., are interactively executed to find a feasible state transition. Nontrivial multi-robot cooperation formation...
The paper presents three mechatronics project courses for the students of the first degree of Bologna program at the University of Maribor, Slovenia. Three courses, Project I, Project II and Project III, are assigned to the project work in the second and third study year. First course, Project I is some kind of introduction into the project work and the students are almost fully supervised by the...
Conventional context-aware system refers to an intelligent mobile system that can sense the Real Space (RS). Its essential functions are to understand the situation in RS as well as to supply suitable information or services to users depending on the perceived situation. In order to realize that, pattern recognition technologies based on signal or image processing (non-symbolic processing) as well...
Context based recognition system, which can improve the accuracy of scene recognition if robots cannot obtain adequate recognition features in the camera, has attracted researchers recently. However, there are few researches which focus on part-whole supplement system based on context which can describe the scene using detail parts in the scene and also reduce the ambiguity of each detail part using...
The internet resources are very rich, and the traditional search engines can accelerate the speed of network information retrieval. But the bilingual translation comparison pages' information in intemet are not fully used. So the combine of personalized search engine and the bilingual auxiliary translation become an important research subject at present. In this paper, basing on the large-scale network-based...
For improving environmental visual perception of indoor robots more accurate and faster, a new model based on image multi-feature fusion is proposed. The hierarchical match mode is used to match real-time collected images of indoor robot with various multi-directional and multi-state images in a database. After establishing a database of 1000 images, average accuracy, average recall ratio and average...
The objective of this paper is to develop a localization system for cooperative multiple mobile robots, in which each robot is assumed to observe a set of known landmarks and equipped with an omnidirectional camera. If only a limited number of landmarks are available, it suffers from law accuracy. In this paper, it is assumed that a robot can detect other robots by using the omnidirectional camera...

The main aim of this paper is to design a hybrid force-position controller using fuzzy logic (FL) for the robotic arm of a 9 degrees of freedom (DOF) upper limb wearable exoskeleton rehabilitation robot. The robot is designed and built in our lab for assisting in the rehabilitation of patients post-stroke. The robotic arm of the rehabilitation robot is driven by pneumatic muscles (PM) and its dynamic...
State Stadium of Costa Rica is the key supporting-construction project of China, because Costa Rica is located in the volcanic active belt in west pacific coast watershed of central American, it is a country there often happens earthquakes. Internal and external arch of the scheduling stadium canopy is a big spanned and high height steel structure. In order to improve construction quality, and to...
In view of the complexity and high cost of image processing system, the real-time image processing system based on SOPC (System-on-a-Programmable-Chip) is proposed in this paper. The embedded Nios II soft-core processor is used to collect and process the image and the algorithm which has the features of simplicity and great data quantity and parallelism is implemented by the hardware in FPGA. By this...
It was discovered that quaternion can be used in surgery navigation system (SNS), as an alternative and compact way to represent rotations. Coordinates conversion must be included when localizing in different coordinate. The application of quaternion in SNS coordinates conversion and the application of space registration in SNS are theoretically introduced in detail. The result of simulation shows...
