UBU proudly reports thatUBU-SCiUS students won gold and silver medals from the International Science Technology and Engineering Competition (ISTEC 2020). The event was held from 13 - 16 January 2020 at Grahapos Indonesia, Bundung, Indonesia.
Participants of this event were high school students from Lukhamhanwarinchamrap School, the local partner school under the Science Classrooms in University-Affiliated School Project (SCiUS) supervised by Ubon Ratchathani University.
As a result of the competition, the project titled Smart Box for Preventing a Motorcycle Accident won the gold medal. The team members consisted of Mr. Pannatat Bupta and Mr. Apiwit Khusiri, grade-10 students. Furthermore, the project titled Ping Pong Smart Robot won the silver medal. The team members consisted of Mr.Pongprawee Rattanasri and Mr. Porames Klangmongkol, grade-11 students. Both of the team’s supervisors were Assistant Professor Dr. Nadh Ditcharoen, UBU lecturer and Mr. Satapisat Kraisri, teacher at Lukhamhanwarinchamrap School.
Below are the abstracts of each project:
The Smart Box for Preventing a Motorcycle Accident’s abstract
The objectives of this project were 1) to build a smart box attached to a motorcycle to prevent an accident, and 2) to develop an android application to control the smart box. Based on IOT technology, NodeMCU and sensors were used in the development. The android app was developed using Thunkable with Fibase and Google Map API. The smart box functions include helmet wearing detection, owner authentication, heart rate monitoring, and alcohol measurement for prevention of motorcycle start. In addition, the smart box has functions to measure distance, to warn drivers of nearby vehicle in the backs, falls warning, monitoring atmospheric particle and warning for air quality, and CO gas content analysis for engine malfunction detection. The android app is able to display data detected from sensors in real time, to show the location of motorcycles, and to warn drivers of high speed driving and risk of accidents. Users’ satisfaction toward the developed system was evaluated in the preliminary experiment through a questionnaire answered by 10 users. The findings indicated that the average of users’ satisfaction was in the highest level.
The Ping Pong Smart Robot’s abstract
The objectives of this project were 1) to build a smart robot as an automatic ping-pong ball collecting system, 2) to evaluate the effectiveness of the smart robot as a ping-pong ball collector, and 3) to develop an android application to control the ping-pong smart robot. The smart robot was used to help players during table tennis matches. Based on IOT technology, the NodeMCU microcontroller board which can communicate and record data via wifi network was used in the development of the system. In addition, the Pixy CMUcam 5 camera which was set to automatically search for ping-pong balls by writing a set of the operation instructions to calculate the appropriate distance was also used in this system. The accelerometer sensor and android application on a smart phone can detect the movement of the phone and send data in the form of xyz axis, allowing us to write a set of instructions that can control the robot movement by tilting or shaking the phone. With this movement system, the robot can efficiently collect the ping- pong balls in all directions by driving with the Omni wheel. The results have shown that the smart robot can automatically find and collect ping-pong balls, then count the number of collected ping-pong balls and display it via the application. Users’ satisfaction toward the developed system was evaluated by 15 ping-pong athletes at Lukhamhan Warinchamrab school in the 3x3square meters field. The findings indicated that the average of users’ satisfaction was in the highest level.
UBU honorably congratulates the participants who attended and placed in this international competition. The collaborative efforts and dedication that was put forward by the staff and students from the UBU and Lukhamhanwarinchamrap School does not go unnoticed. UBU is proud to have such strong representation of our local partnerships and quality curriculum for science and technology and looks forward to participating in more related events.
