基于设计型学习的机器人竞赛教学设计与实践——以2019年FLL工程挑战赛“太空之旅”为例     

罗倩茹  秦健  刘全铭 《数字教育》2020,(1):72-75

设计型学习强调通过分析、设计、开发和实施的反复循环来改进教育实践,其理念与机器人竞赛的备赛过程一致,因此,可采用DBL的理念开展机器人竞赛的教学过程。本文主要针对机器人竞赛的课堂教学设计,在深入了解众多中小学机器人教学方式的基础上,查阅了国内外相关文献,并结合笔者连续两年深入中小学指导学生参加FLL工程挑战赛的实践经验,不断改进教学策略,以期为一线教师机器人竞赛教学的开展提供参考。  相似文献

Exact Computation of Parallel Robot''''s Generalized Inertia Matrix     

赵永杰  杨志永  梅江平  黄田 《天津大学学报(英文版)》2005,11(6)

According to the definition of the new hypothetical states which have obvious physical sig-nificance and are termed as no-gravity static and accelerated states, a method for exact computa-tion of the parallel robot's generalized inertia matrix is presented. Based on the matrix theory, the generalized inertia matrix of the parallel robot can be computed on the assumption that the robot is in these new hypothetical states respectively. The approach is demonstrated by the Delta robot as an example. Based on the principle of the virtual work, the inverse dynamics model of the robot is formulized after the kinematics analysis. Finally, a numerical example is given and the element dis-tribution of the Delta robot's inertia matrix in the workspace is studied. The method has computational advantage of numerical accuracy for the Delta robot and can be parallelized easily.  相似文献   

Problem Solving in a Middle School Robotics Design Classroom     

Stephen J. Norton  Campbell J. McRobbie  Ian S. Ginns 《Research in Science Education》2007,37(3):261-277

Little research has been conducted on how students work when they are required to plan, build and evaluate artefacts in technology rich learning environments such as those supported by tools including flow charts, Labview programming and Lego construction. In this study, activity theory was used as an analytic tool to examine the social construction of meaning. There was a focus on the effect of teachers’ goals and the rules they enacted upon student use of the flow chart planning tool, and the tools of the programming language Labview and Lego construction. It was found that the articulation of a teacher’s goals via rules and divisions of labour helped to form distinct communities of learning and influenced the development of different problem solving strategies. The use of the planning tool flow charting was associated with continuity of approach, integration of problem solutions including appreciation of the nexus between construction and programming, and greater educational transformation. Students who flow charted defined problems in a more holistic way and demonstrated more methodical, insightful and integrated approaches to their use of tools. The findings have implications for teaching in design dominated learning environments.  相似文献

Virtual local target method for avoiding local minimum in potential field based robot navigation     

邹细勇  诸静 《浙江大学学报(A卷英文版)》2003,4(3):264-269

A novel robot navigation algorithm with global path generation capability is presented. Local minimum is a most intractable but is an encountered frequently problem in potential field based robot navigation. Through appointing appropriately some virtual local targets on the journey, it can be solved effectively. The key concept employed in this algorithm are the rules that govern when and how to appoint these virtual local targets. When the robot finds itself in danger of local minimum, a virtual local target is appointed to replace the global goal temporarily according to the rules. After the virtual target is reached, the robot continues on its journey by heading towards the global goal. The algorithm prevents the robot from running into local minima anymore. Simulation results showed that it is very effective in complex obstacle environments. Project (No. 69904009) supported by the National Natural Science Foundation of China  相似文献
