The paper details the rationale for adopting 'structured' design and build projects as a major element of the program and their role in integrating theoretical and practical knowledge whilst also developing the essential managerial and personal skills needed to design and produce modern-day mechatronic artefacts.

The design is based on ultrasonic communications, thus obviating the need for an umbilical cable. The control of the robot is distributed on a local area network which connects all the actuators and sensors. The robot has four legs, powered by compressed air which allows the robot to 'walk' over obstacles. As it can have negative buoyancy, it can also 'walk' along the roof of the pipe if there are obstacles on the floor. The robot also has electrically driven propellers, so that it can 'swim' when having neutral buoyancy. Sensors include a TV camera and ultrasonic imaging of the inside pipe surface. The project described is a joint-venture between City University of Hong Kong, through Pearl Technologies Ltd., Portsmouth Technology Consultants (Portech) Ltd. and the Robotics Research Institute at Harbin Institute of Technology in China.","PeriodicalId":261635,"journal":{"name":"Proceedings Fourth Annual Conference on Mechatronics and Machine Vision in Practice","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129644246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The solutions deal with the controlled penetration of tissue interfaces, tissue discrimination methods and the control of tissue position. Interpretation methods require anticipation of the deformation behaviour of frames and use features that are characteristic of the sensory data to achieve this. Automated interpretation of state enables automatic selection and scaling of tool strategy. It is shown through the study that reference models can be used successfully to determine the state in such complex working environments and, in addition, that neural networks can also be applied to achieve the same goals. In the latter case unique methods for learning from a minimal data set have been developed and implemented. The project has provided significant leads in this research field and provides the potential to deploy mechatronics tools to a wide range of precision surgical procedures. In most situations when a tool approaches a target position in the body the deflection or deformation of tissues under tool action is significant and is often unacceptable for quality results. It is known that scanners operate with great precision and the results of this project offer techniques to control tool movement to a similar working accuracy whilst taking into account movement of tissue. The article presents mechatronic systems for 4 surgical procedures.","PeriodicalId":261635,"journal":{"name":"Proceedings Fourth Annual Conference on Mechatronics and Machine Vision in Practice","volume":"1 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124212462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first part of the paper is dedicated to the presentation of the multisensor system and the specific calibration process which allows it to register color and range data in a unique frame. The next part describes the region growing algorithm used for the 3DC image segmentation. The color criterion used to select homogeneous pixels is defined in a perceptual representation space. A 3D criterion is used to select voxels which belong to the same planar face in the observed scene. We show how these two criterion may be combined to segment the 3DC image into planar faces characterized with homogeneous color. Results obtained with real dense 3DC images illustrate the performance of this method.","PeriodicalId":261635,"journal":{"name":"Proceedings Fourth Annual Conference on Mechatronics and Machine Vision in Practice","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131536786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the robot is to automate the cloning of plant material in a sterile environment, a process that is entirely manual at the present time. The robotic process mimics the manual process and involves harvesting a small (6 cm) plant from a tray, cutting it into a number of smaller viable explants and planting these into fresh trays of nutrient medium. This must all be done under sterile conditions. ForBio has identified agro-forestry for pulp and timber products as a large enough market to warrant the cost of automation.

There are some approaches of combining those modelling techniques, all having to make certain limitations and extensions of the techniques in scope. Here, it is intended to translate the models from one representation to another, without making any changes to the techniques themselves. This is a consistent approach since extending an existing technique always means modifying everything from the very definitions to the tools for the technique. Different techniques discussed are neural networks, Petri nets, and fuzzy systems.

This paper explores the limitations of hand-crafted minimalist robot control mechanisms based on a neural paradigm, and then shows that these mechanisms are well suited to robot training using well understood neural learning mechanisms. Training a robot is more powerful than other methods more commonly used for robot learning (such as reinforcement learning and genetic techniques). A trained robot is told more than whether it was wrong or right for a particular action or sequence (reinforcement learning), the robot is also told what it should have done (supervised learning). Robots can hence develop appropriate behaviour much more rapidly. The neural mechanisms and training techniques have been developed on a kinematically realistic simulator. The mechanisms have been ported from simulated vehicles to a real vision guided robot: CORGI. Results from the simulation and CORGI are presented.","PeriodicalId":261635,"journal":{"name":"Proceedings Fourth Annual Conference on Mechatronics and Machine Vision in Practice","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131249719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interfaces presented here illustrate a range of techniques which vary from pulse processing units plugged directly into the PC data bus to simple switches and sophisticated constant current servo amplifiers which plug directly into a PC printer port. Motion control is emphasised because students can visually relate system behaviour to the computed performance thus providing immediate learning feedback.
