They are four students Vu Xuan Lai, Thai Cong Khanh, Vu Tien Tung and Nguyen Manh Cuong from K55CA class, Information Technology Department of Engineering and Technology University (VNU) sharing the same passion for scientific research and achieving many successes in contests Parabolic Flight 2013 and Students doing science research at university level in 2014.

The group of four students of IT faculty sharing the same passion for scientific research and this has brought them together. Since March 2013, Dr. Le Thanh Ha – lecturer of IT faculty said to K55CA class about the Parabolic Flight contest, which Vietnam has attended for the first time. The four students were in two different groups but having same idea of Gyroscope. After presenting the idea to examiner board and experts from The Japan Aerospace Exploration Agency (JAXA), they were suggested to merge into one group.  Their product was brought to Japan to experiment and achieved high results after assessments of the university and Japanese experts. From mid- August 2013 to mid-October 2013, the group have brainstormed and designed laboratory equipment.

At the beginning, the group’s idea was target to “The movement of gyroscope in weightless environment” but then they changed to a more practical experiment is comparing the differences between Gyroscope and Accelerometer parameters in two environment to find out solutions for game publishers to tweak parameters of Gyroscope and Accelerometer for game based on them can play in ISS. 

Showing abilities in difficulties

This was the first time Vietnam taking parting in weightless experiment so that we did not have documents and materials of processing way or the products they need. Vu Xuan Lai shared that in order to fully understand  performing experiments as well as workflow, besides documents provided by JAXA, we had searched on the Internet weightless experiments, especially referenced how to making experiment equipment of Thailand, Malaysia, and Japan teams.

The second was making the device. The four members were students of IT faculty so their knowledge of mechanics and electronics was limited. Moreover, this was the first time so the making of equipment serving for experiment in weightless environment was very difficult. The group had to spend 1-2 first weeks under instruction of Dr. Le Thanh Ha to achieve success in making devices.

In order to have experimental products, the group had to overcome funding difficulties. Vu Tien Tung said that they had to be self-conscious and saving from their living expenses to complete the product. So that, the entire cost for making equipment was from group members’ monthly saving.

Thai Cong Khanh said “after everything has been stable in terms of manufacturing equipment as well as programming testing software to obtain underground data. All of us had thought that the experiment would be successful but one day before taking off, our software had been error and collected data had not been correct. We had spent that day to recheck and fix it as well as recheck the equipment’s operation before the “zero hour”. The remaining time was not much but with effort, passion, and responsibility, they have overcome all difficulties.

Besides these difficulties, with the guidance and help from Dr. Le Thanh Ha with lectures of IT, Electronics and Telecommunication, Physics and Engineering, and MEP faculties as well as Japanese experts had created favorable conditions for the group completing the experiment.

The four members had been very excited to be the pioneer group representing for Vietnam. The contest was the chance for group to exchange and study learning and working experiment from Japanese group in particular and others in Southeast Asia in general. Although our group was the newest one but our experiment was not inferior to others in terms of ideas and implementing methods. With the simplicity and sophistication in the design of hardware and software, the result they achieved in the two days of Parabolic Flight contest was very positive. That was the basis for evaluating initial recognition and serving to research and develop experiment.

Completing the product in the near future

After more than a year of developing and passing a series of tests of Japan, the system had operated properly. In the near future, the group will focus on innovating shape and structure of the equipment as well as updating related documents to prepare for “Talented young researchers” in 2014 held by Ministry of Education and Training. Nguyen Manh Cuong said that the system would evaluate the accuracy of the sensor in terms of different gravity. The collected data will be used in reality application such as improving gaming experience, mini mobile satellite having smartphone as brain etc.

Through this competition, the group wants to send a message to students be passionate to do science research in particular and aerospace in general that let pursue your passion and participate in scientific research regularly. That will be the basis for your succeed and future development.

The “The interaction of Accelerometer and Gyroscope in Microgravity Condition” product of Vu Xuan Lai, Thai Cong Khanh, Vu Tien Tung, and Nguyen Manh Cuong from K55CA, IT faculty under the instruction of Dr. Le Thanh Ha and Dr. Nguyen Thi Nhat Thanh, had passed 9 proposals of Asean countries to become one of three excellent proposals to perform weightless flight in Japan.

The group’s product had won first prize in the student researchers conference at university level in 2014 and selected to attend Vietnam Y

oung researcher prize at Ministry of Education and Training level in 2014.

Their product includes a storage rack, motor, controlled circuit, propeller, smartphone device and written software to collect and analyze data. Their purpose is checking whether game can be played in space (weightless environment) or not so they used three smartphones are Lumia 920, Samsung Galaxy SII and iPod 4th generation to conduct experiments. The three smartphones would be attached to 3 “propeller” connected to the motor and worked based on the controlled circuit on a horizontal surface. They have set for the propeller at three speeds 20-40-60 cycles/ minutes through the controlled circuit. Three phones had been installed with “Parabolic Flight 2013” app written based on 3 different platforms to measure angular parameters, velocity through Accelerometer and Gyroscope sensors available in the phones. The data analysis software will analyze the collected parameters. The Parabolic Flight experiments will be premise for the following group’s plans such as mini monitoring satellite with smartphone be processing brain. With powerful processor, the compact sensor etc. and finally is two Gyroscope and Accelerometer sensors will play a role as a part of the navigation, and smartphones having full of necessary components of a satellite.
