<![CDATA[Beautiful music requires precisely tuned instruments. Tuning a guitar is necessary for any guitarist on their first day. This work demonstrates an understanding of the critical characteristics that must be considered while developing an acoustic guitar tuner and the logical process of designing such a tuner. The study aimed to create an algorithm using the Butterworth Filter and Fast Fourier Transform (FFT) capable of adequately analysing the frequency spectrum of a plucked guitar string to determine its fundamental frequency. The developed system compared the detected frequency and the standard frequency of the picked guitar string, which then requested the user on the tuning state of that corresponding string. The error in frequency detection was found to be in the order of 0.02%. The MATLAB App Designer tool created a Graphical User Interface (GUI) that users could use to easily tune guitars using the generated application. The implemented tuner overcame the steep learning curve and high sensitivity of traditional ones.]]>

<![CDATA[Human-Robot Interaction (HRI) is an interaction between humans and robots through verbal and/or non-verbal cues. Studies in the HRI field concern the psychological effect, especially reactance, experienced by humans in decision-making situations with robots. This study applied persuasive attempts to investigate the impact of social praise by a social robot on human psychological reactance in a decision-making situation. The robot socially expressed its recognition (an acknowledgement of the existence) and reassurance (the action of removing someone's doubts) towards humans in a game, namely "Survival in Island". Social praise was expressed verbally in adoring human activities, such as 'Good Job' for following the robot's decision-making suggestions. The study randomly divided the participants into two conditions (social praise: presence vs absence) in a between-subject design study. Besides using questionnaires to measure humans' psychological conditions, the level of stress experienced by humans was also collected using a Galvanic Skin Response (GSR) sensor. The results indicated significant effects of social praise on perceived ease of use toward the robot, perceived intention to use the robot again in the future, perceived belief towards the robot and perceived compliance with the robot's suggestions through MANOVA tests. The study did not find other significant psychological and physiological effects of praise.]]>

<![CDATA[The rise of technology has induced the development of robots that engage with humans through social interaction. The robot is believed to be capable of assisting humans in their life. However, the current technology is still far from a fully autonomous robot as there are many limitations. Additionally, it is unclear whether the current social robot effectively influences social reactance in Human-Robot Interaction (HRI). The study's objective is to investigate the influence of social cues used by the social robot on human social responses for HRI applications. Also, the study validates the reactance scale used in the questionnaire by correlating the measure with Galvanic Skin Response (GSR) readings. The study proposes a Wizard of Oz (WoZ) approach to observe HRI through decision-making games. A social robot is programmed to persuade participants to make choices. The participants' decisions made during the experiment and their GSR reading are recorded, and then they are asked to answer questionnaires. Statistical analyses are done on the collected data using the regression and MANOVA statistical tests. As a result, there is a significant correlation between GSR reading and enjoyment. Regarding social cues, the participants feel more relaxed when the social robot exhibits social cues in High Controlling Language (HCL) conditions rather than Low Controlling Language (LCL) conditions. Furthermore, the Attitude trait of the social robots greatly influences human perceived social intelligence towards the robot.]]>

<![CDATA[With the increasing potential of satellite technology, it becomes crucial to learn its principles and develop the basic satellite subsystems for the undergraduate level. Working on a real satellite is a challenging target and requires a solid technical background. In contrast, less complex models, such as CanSat, CubSat and HeptaSat, introduce basic ideas to the undergraduate studies level. This paper presents the CanSat design and implementation for remote sensing applications such as measuring the CO2 level in contaminated areas. The CanSat has the size of a soft drink can and simulates the subsystems of the satellite (e.g., payload, power, communication, onboard computer, and structural). Its mission was to be released from a certain altitude and send real-time data to the ground station during landing. The design process was elucidated at the subsystem level. It included the mission requirements and specifications, component selection, and software and hardware design. Arduino Nano was utilised as an onboard computer. A printed Circuit Board (PCB) was designed using Diptrace© to connect the electronic components to Arduino Nano. Xbee was used as a communication module to send the collected data to the host computer. This data was visualised in real-time by LabView©.]]>

<![CDATA[This paper describes the design process and prototype development of a remotely controlled airship for wireless coverage. The airship is designed to be used as a platform to provide wireless coverage for rural areas. The design process follows a systematic design process for lighter-than-air vehicles, modified to impart slight heaviness to the vehicle. A remotely-controlled, thrust-vectored electric propulsion system offsets the slight vehicle heaviness. The electric propulsion system comprises two tilting rotors for takeoff, cruise, hovering, and horizontal manoeuvring. A rudder-less, rotor-less, cruciform fin design was implemented. A reduced-scale prototype of the airship was developed to prove the design concept. The airship prototype was successfully tested in an indoor environment. It was discovered that propeller tilting enables the dynamic thrust vectoring demanded by the various flight manoeuvres. If the airship can fly, no one will have to handle its flight when it is needed for wireless coverage.]]>
