Freedy","doi":"10.1109/OCEANS.1983.1152126","DOIUrl":"https://doi.org/10.1109/OCEANS.1983.1152126","url":null,"abstract":"Underwater manipulation continues to pose challenges to both robotics and computer technologies. With recent advances in sensor and artificial intelligence technologies, \"intelligent\" robotics presents a novel and effective solution to coping with problems typically encountered in underwater manipulation tasks. To date, a number of manipulation systems with computer-based self-monitoring and planning capabilities have been demonstrated. While the principal contribution of these systems is to replace, augment, aid or improve operator performance in underwater tasks, overall system performance still depends on the effectiveness of the combination between the robotic system and the human counterpart. To this end, an \"intelligent\" interface (I^{2}) is proposed as a means to dynamically manage information, allocate tasks, and actively mediate between the operator and the robotic manipulator in a manner that optimizes their joint performance. The potential efficacy of theI^{2}is discussed in relation to specific aspects of remote supervision in underwater manipulation tasks (e.g., effective data portrayal, plan communication, contingency handling, and task monitoring). An example of a link between AI and a mechanical underwater manipulator is shown via a prototype system, Task-Oriented Supervision Command System (TOSC). TOSC is a procedural net-based supervisory planning system that provides interactive programming of manipulation tasks in a high-level command language. A series of experimental studies were performed to evaluate TOSC features on a remotely-controlled six degree-of-freedom anthropomorphic manipulator system with an integrated control and display console. Laboratory evaluation of underwater manipulation and maintenance tasks at various levels of task complexity and manipulation difficulty was conducted. The results showed TOSC to be a highly effective and well accepted aid that both improved performance and reduced errors, especially in complex manipulation tasks under uncertain environmental conditions.","PeriodicalId":137921,"journal":{"name":"Proceedings OCEANS '83","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130601543","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}

After 10-1/2 years of ocean exposure at water depths of 1,840 to 5,075 feet, the major findings include: (a) The implosion (failure) strength and stiffness of the concrete spheres and the uniaxial compressive strength of concrete specimens increased during the first 5-1/2 years exposure in the ocean and remained essentially constant during the next 5 years; (b) There has been no evidence of seawater permeating through the walls into the interior of ocean-exposed spheres externally coated with a waterproofing material; uncoated (bare concrete) spheres have a very low rate of water ingress, i.e., a permeability coefficient of about10^{-14}ft/ sec; and (c) Visual inspection and microstructure examination of retrieved specimens have not revealed any significant deterioration of the concrete matrix; no corrosion was visible on steel reinforcing bars which had as little as one inch clear cover. This program has been a decade-long demonstration of the effective use of concrete in the ocean; it has been shown that concrete is a durable, reliable material for pressure-resistant structures for long-term deep-ocean applications.","PeriodicalId":137921,"journal":{"name":"Proceedings OCEANS '83","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125235739","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}
