In this paper, the operability of a custombuilt differential drive wheel mobile robot was evaluated using a self-driving algorithm in practical application. Several key parameters need to be realized by the WMR to enable succinct self-driving algorithm evaluations and parameter derivations. The main components of the WMR development were examined in this work, specifically parameter derivations, hardware implementation, steering algorithm and WMR operability. The result obtained indicate that with proper design and careful calibration of sensors, the required driving parameters could be realized. This enables the WMR to potentially serve as data collection platform for future evaluation of self-driving algorithms.

Learning to program at a stationary computer for any programming course can be boring and demotivated especially when dealing with complex syntax details. A more hands-on approach utilizing robotic module will lead to a better task-oriented interaction between students and their real-life surroundings hoping to increase student engagement with programming. Thus, this paper proposed a constructionist robotic module to facilitate learning in C programming curriculum utilizing a microcontroller board known as FRDM-KL05Z. The module consists of several input and output components that can be utilized to establish human-machine interaction depending on the instruction code written by the students. A pilot survey was also carried out to assess overall impression of the student towards the proposed approach in teaching and learning activities. Results indicated that students were satisfied with the approach as it help to improve their understanding in C Programming.

The term plasma is often referred to as the fourth state of matter. When sufficient ionized, plasma can be a conductor element. Plasma antenna is a type of radio antenna that represents the use of ionized gas as a conducting medium instead of metal conductors. The main objective in this research is to design plasma antenna at 2.4 GHz by using commercial fluorescent tube. In this work the commercial fluorescent lamp was chosen because it was low cost to produce plasma element. The plasma antenna in this research was made from fluorescent lamp that functioned as a radiating element with target frequency at 2.4 GHz for Wi-Fi application. The commercial fluorescent lamp consisted of argon gas and mercury vapor with a diameter of 28 mm and a length 589.8 mm. The result showed that a fluorescent tube, can be used to work as a plasma antenna for Wi-Fi application.
