For this reason, this study aims to create an enhanced oculus cane which uses a photodiode to help the visually impaired people detect objects, and mobilize freely and safely. To assess its effectiveness, a PN photodiode was utilized which detects objects with programmed barcodes in various distances and sizes. Response time in identifying objects was tested together with the loudness of audio volume measured in decibel. The cane is used mainly in the household, wherein barcodes are scanned by a photodiode connected to a Bluetooth module and transmitter. The Bluetooth module and transmitter are linked to a digital amplifier audio board and double diaphragm speaker, which are used to verbally transmit the name of the object with barcode. The results proved the capabilities of the Oculus cane with 1.60 seconds response time, and scanning range in distances of 4 cm. (minimum) and 22 cm. (maximum), and the sizes of the barcodes 3 cm. and 5 cm. The loudness of the audio volume from the speaker of the Oculus cane was 82.7 dB, the safe level which will not cause damage to the ears. It is therefore recommended to use the enhanced oculus cane with photodiode as an alternative to existing smart canes which is more affordable and offers features which will greatly help visually impaired people live an independent and safe life.","PeriodicalId":153802,"journal":{"name":"International Journal of Applied Science and Engineering Review","volume":"87 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":"134542717","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}

For this reason, the objective of this study is to create a motorized whiteboard eraser out of a car windshield rubber blade from a broken car. With the help of Arduino Uno and Arduino Interface, an open-source electronics platform based on easy-to-use hardware and software, was able to help read the coding and inputs in causing the wiper move with a switch, battery and motor. The results of the study showed that the time of executing the command was 0.35 seconds after turning the switch on, while the distance covered in centimeters by the motorized whiteboard eraser was 75cm. It is also noted that after four rounds of horizontal swiping directions it had totally erased the writings on the whiteboard. Further, in terms of the speed of erasing the writings, the shortest time was 0.0852 miles per hour. Proving its efficacy on erasing various percentages of shaded parts it is recorded that in 50% shaded part it took a minute and six seconds, while in 75% shaded part it took one minute and 20 seconds, lastly, in a 100% shaded it could totally be erased in a span of one minute and 36 seconds. As a result, it is recommended to increase the speed of the motorized whiteboard eraser by utilizing a bigger motor with a higher RPM capacity. Moreover, it is advised that the whiteboard eraser be improved in order for the rubber blade to entirely adhere itself to the whiteboard in order to have less constraints on erasing. It is also recommended that you choose a lighter material than PVC in order for the eraser to operate smoothly.","PeriodicalId":153802,"journal":{"name":"International Journal of Applied Science and Engineering Review","volume":"204 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":"132985446","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}

To synergize with those evolution, the education system also needs to evolve to make sure that the educational material contains follow the trends of automation and increase the level of understanding about technological developments. Based on a survey given to Industrial Engineering students at Diponegoro University who were studying the Integrated Manufacturing System courses the class said that automation tools are very important in processes in industry, but their understanding about the description of the automation in the industrial world have a different understanding level, their level of understanding was 35%. understand, 35% quite understand and 30% do not understand. Therefore, the researcher designed a learning media based on student requirement and Curricullum of Intregated Manufacturing System Subjects to support an understanding of automation learning, especially Industrial Robotics. The learning Media use the Engineering Design Process method, to obtain a teaching tool that is in accordance with existing requirements, its called Arm Manipulator Robot whose using Internet of Things to do material handling work.
