摘要： The aim of this study is the analysis of the state of the art in consumer robotics dedicated to personal care and housekeeping, for further critical analysis of it. After interviewing different users we will follow a methodology to find the voice of the customer. From these interviews we get the customer's needs which will be structured and ordered in a hierarchy that will help us to set the priorities, concluding with the design requirements and the basic features that the robot must have.

关键词： Experiential learning   Electronics subject matter in robotics   Robotics learning content design   Higher order thinking skills  

摘要： The purpose of this paper is to investigate whether the experiential learning of electronics subject matter is effective in the middle school open learning of robotics. Electronics is often ignored in robotics courses. Since robotics courses are typically comprised of computer-related subjects, and mechanical and electrical engineering, these three areas should be emphasized equally. Many studies reveal impressive learning of computer science and mechanical engineering, but clear evidence of the effectiveness of electronics learning in the higher order thinking skills of middle school students is still lacking. We designed three different robotics courses with electronics subject matter introduced through experiential learning. A parallel group design was used, where three different open learning courses were implemented for middle school students. Based on results of the first and second implementations, we improved students' learning of relevant content for each successive step of the experiment. In total, 381 middle school students participated in all experiments and were surveyed using pre- and post-tests. The collected data were analyzed using a quantitative research methodology. The findings revealed that the teaching approach was effective. During the learning process, student interest in robotics increased, and overall achievement improved with a medium effect size (eta(2) = 0.13). The best results for the learning of electronics subject matter were found in the learning process (eta(2) = 0.44), where experimental sharing of electronics parts was the most evident approach used by the students. Examination of learning material structure in light of the shared electronics subject matter is analyzed and discussed and possible directions for future research are presented.

摘要： Several authors insist on the importance of students' acquisition of spatial abilities and visualization in order to have academic success in areas such as science, technology or engineering. This paper proposes to discuss and analyse the use of educational robotics to develop spatial abilities in 12 year old students. First of all, a course to introduce robotics to 6th grade primary school students was designed. The key intention was to prepare practical and motivating sessions in order to foster the students' involvement in hands-on learning. Hence, during the sessions of the course, challenges were provided for the students, in order to develop their capabilities as proficient problem solvers. The teacher assisted and guided the students, and the students were encouraged to solve the problems by themselves, working in 3-members teams. The main goal of this paper is to discuss and analyse the potential usefulness of educational robotics to develop spatial abilities. To carry out the analysis, students were randomly divided into an experimental group (EG), which participated in the robotics course, and a control group (CG), which did not take part in the robotics course. The extensive existing literature for spatial ability evaluation was analysed and reviewed and a pre-test and a post-test were prepared for use in the research study. Initially, the spatial ability of both EG and CG students was assessed with the pre-test. Then, after finishing the robotics course, the same sets of students were tested with the post-test. An extensive analysis of the results is provided in the paper. Results show that the positive change in spatial ability of the participants in the robotics course (EG) was greater than change evident in the students who did not join the course (CG). The improvement was statistically significant. The results also show that the overall performance of the students depends on the instruments used to evaluate their spatial abilities. Hence, this study

摘要： Mobile machining with industrial robots is proposed to be a cost-effective and portable alternative to large-scale CNC machine tools in machining of large-scale parts designed in aerospace, nuclear manufacturing and energy industries. Although robotic machining offers several potential advantages, it is also subject to major technical challenges. In this paper, the dynamics of a hexapod platform utilized for robotic milling is investigated in terms of rigidity, position-dependent dynamics and cross compliance caused by the complex kinematic chain. Considering the dynamic flexibility of the robotic platform, its effects on tool-tip dynamics are examined. The effect of the robot position relative to the workpiece on the dominant modes observed in transfer functions is discussed, which may be further used to locate the robot to attain better stability depending on the case. The dynamic responses at the moving platform and at the tool tip are measured through tap tests. Although the paper does not focus on modelling, the results can be generalized to mobile machining with hexapod robots.

摘要： We describe a general approach for using linearizing feedforward control inputs for large degree of freedom (dof) multi-limb robots operating in scenarios involving motion and force constraints, and under-actuated degrees of freedom arising from the task and the environment. Our solution is general and has low computational cost needed for real-time control loops. It supports the tuning of the feedforward term to meet multiple task objectives. Being structure-based, it is able to easily accommodate changes in motion and force constraints that often occur in robotics scenarios.

摘要： The modifiable walking pattern generation (MWPG) algorithm can handle dynamic walking commands by changing the walking period, step length, and direction independently. When an infeasible command is given, the algorithm changes the command to a feasible one. After the feasibility of the navigational command is checked, it is translated into the desired center of mass (CM) state. To achieve the desired CM state, a reference CM trajectory is generated using predefined zero moment point (ZMP) functions. Based on the proposed algorithm, various complex walking patterns were generated, including backward and sideways walking. The effectiveness of the patterns was verified in dynamic simulations using the Webots simulator.
