With the specific goal to limit the expensive process of polishing due to unhealthy conditions, trained workers requirement and human mistakes, it is an attractive idea to automate the surface polishing by machines. The important job in robotic polishing process is path planning and force control. This research work is with the objective to systematize and optimize the path planning for free-form surfaces under the regulated force. Robotic polishing based on CAD models of the workpiece is presented in this paper. A new technique of path planning for symmetrical free-form surfaces is used. The proposed method is tested for the polishing of a glasses frame. Finally, the optimized path planning idea for the symmetrical free-form surfaces is compared with other path planning methods in terms of quality and productivity.","PeriodicalId":191997,"journal":{"name":"Volume 5: Engineering Education","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131651085","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}

Djuric","doi":"10.1115/IMECE2018-86865","DOIUrl":"https://doi.org/10.1115/IMECE2018-86865","url":null,"abstract":"The objective of this research is to develop a Virtual Teach Pendant for Android Cellphones (VTPAC) that is able to communicate with the robot model in the Visual Components software ⌈1⌉ ⌈2⌉. The VTPAC is a force multiplier that allows users to gain valuable teach pendant experience in labs with few robots, and makes the actual real-world robot time more valuable. It is also like a graduated driver’s license where the student must prove some proficiency with the VTPAC before being allowed to get behind the wheel.\u0000 The VTPAC will be used to operate the real robot system too and will allow people to be trained without using real robotic systems in very safe environment. The VTPAC can be used for industrial training and can be integrated in the academic programs, especially for online courses.\u0000 In this research, the Fanuc LR Mate 200iC robot and the Visual Components software have been selected as a case study. These choices were made because of the easy access to the Fanuc LR Mate 200iC and this interface by reason of it can control the robot the same way as the Teach Pendant in the real world.\u0000 Using the robot kinematic theory to understand the Teach Pendant commands, the code was developed such that it respects the operating mode of the robot and all the security operations needed. For the VTPAC development we used Python to communicate with the Visual Components software to work as a client for the software. This can allow users to utilize its own cellphone as the teach pendant and the software as the robot, having a more real experience in a safe environment. The VTPAC has been implemented and tested successfully.","PeriodicalId":191997,"journal":{"name":"Volume 5: Engineering Education","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128422472","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 essential components for remote teaching are easy access, usefulness, social interaction, and flexibility of time and place. Tecnológico de Monterrey (ITESM) has recently implemented a program to promote the visit of foreign professors to Mexico, this initiative is called PEV (foreign visitor professor). One way to get more benefits from the program is to invite them to give distance classes once their presence year in Mexico has ended.\u0000 This case study describes student satisfaction with the theoretical-practical courses taught through the real-time distance learning method in the School of Architecture and Industrial Design. The determining factors in the student approval were defined as: the learners’ inclination to take similar courses, the quality of contact between teacher and students, feeling inspired by the professor, and recommending the course to other students. The primary factors of novelty, flexibility, and utility of the remote format were measured using a Likert-type scale. The findings revealed a notable level of acceptance by students. Specifically, the course format factor was positively valued by the sample. These findings are significant to Latin American and international universities because they describe one way to improve their distance or remote teaching and learning offerings.","PeriodicalId":191997,"journal":{"name":"Volume 5: Engineering Education","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126058126","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 lecture portion of the course was developed as approximately 80% online. The students and instructor met in person for the lecture portion of the course once every other week for 50 minutes, with the remaining activities completed online. The laboratory portion of the course remained in the traditional face-to-face format. Specifications grading was used to determine final course grades. This paper will describe the course structure, types of assignments, and use of face-to-face class time. Student performance in the hybrid course is compared to previous student performance in the same course taught in a face-to-face format. Student feedback and instructor observations are shared.","PeriodicalId":191997,"journal":{"name":"Volume 5: Engineering Education","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124160081","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}
