The Lookprabida formula student team uses an electronic throttle control (ETC) system in the racecar. Unfortunately, the ETC system cannot regulate the throttle valve to closely pursue angular setpoints. Thus, this paper endeavors to improve the response of the ETC system in racing cars. The ETC system is first examined using frequency response ana...

Soft actuator technology is extensively utilized in robotic manipulation applications. However, several existing designs of soft actuators suffer from drawbacks such as a complex casting process, a multi-air chamber configuration, and insufficient grasping force. In this study, we propose a novel soft bellow design featuring a single air chamber, w...

In the well-known and widely used lateration and weighted centroid localization (WCL) methods, as received signal strength indicator (RSSI) based methods, the position of an unknown target is estimated by using the reference node positions and RSSI levels, which represent the distances between the target and the reference nodes. Since the path-loss...

In this paper, implementation and validation of a target tracking system based on the received signal strength indicator (RSSI) for an indoor corridor environment of the hospital is presented. Six tracking methods of a moving target (i.e., equipment, robot, or human) using RSSI signals measured from two stationary reference nodes located at the dif...

Around-view monitor applications have increased the value of monitoring technology for the automotive market. Most previous applications have used a bird’s eye viewpoint that offers a limited field of view for the driver. In this study, we propose an algorithm of multi-process to stitch the full panorama view that was captured from multiple cameras...

Most of the applications in mobile robots use the image data from the monitoring system to compile algorithms. The undesired movement in the video is an obstacle to compute commands, and it requires to reduce this motion for stabilizing the videos. Thus, we presented a dual system to remove the undesired movement from global and local motion by the...

Recorded video data must be clear for accuracy and faster analysis during post-processing, which often requires video stabilization systems to remove undesired motion. In this paper, we proposed a hybrid method to estimate the motion and to stabilize videos by the switching function. This method switched the estimated motion between a Kanade–Lucus–...

This article presents the mixed phase as the pressure medium of hydraulic artificial muscles, which has rarely been mentioned before. Then a novel mixed phase activated artificial muscle is designed. Through this method, the weight of artificial muscle can be reduced effectively compared with the traditional hydraulic artificial muscles. The artifi...

This paper presents a development algorithm of hemi-cylinder projection plane applied in panorama view of AVM applications. This projection plane is established to maintain the FOV in horizontal axis. The calibration parameters are estimated with OcamCalib toolbox, and comparison of keypoint detection are showed as experimental results. Our panoram...
