Abstract

Path planning is an important aspect in robotics, allowing a robot to reach its destination safely and efficiently. The Informed Rapidly-exploring Random Tree Star (Informed RRT*) algorithm has become one of the popular path planning methods due to its efficiency and ability to handle complex workspaces. Since its introduction in 2014, various variants of Informed RRT have been developed to improve its performance. However, there has been no comprehensive study comparing the performance of these variants. This research aims to conduct a comparative study of the performance of several Informed RRT variants in solving path planning problems. The algorithms compared are APF-IRRT, BI-RRT, Informed RRT* + DWA, Informed RRT*-Connect, Informed RRT*-PSO, MI-RRT-Connect, and Informed RRT* with wrapping** procedure. Algorithm performance is evaluated based on computation time and path length metrics. Experiments were conducted on various path planning scenarios with different complexities. The results show that certain Informed RRT variants perform better than others in different metrics. APF-IRRT and Informed RRT-Connect* generally have faster computation time, Informed RRT-PSO* and Informed RRT with wrapping procedure produce smoother paths. This research provides a better understanding of the strengths and weaknesses of Informed RRT variants, enabling the selection of appropriate algorithms for specific path planning applications.

Abstract

This research aims to develop a dynamic speed control system for line follower robots by integrating computer vision technology and PID control. The main challenge in controlling line follower robots is maintaining stability and speed while navigating various types of turns and complex paths. This study proposes the use of computer vision to detect paths more accurately and responsively, and PID control to dynamically adjust the robot's speed based on detected errors. The research methods involve simulating the e-puck robot in a Webots environment, developing algorithms for black line detection and error calculation, and designing the PID control system. The test results show that in Arena 1, the completion time with fixed base speed is 58.08 seconds, while with dynamic base speed it is 50.386 seconds, indicating a 13.3% reduction in completion time. In Arena 2, the completion time with fixed base speed is 71.584 seconds, while with dynamic base speed it is 66.624 seconds, indicating a 6.9% reduction in completion time. Thus, this control system is more effective in keeping the robot on the desired path, reducing deviations and improving path tracking accuracy.

Abstract

Dimensional measurements in the manufacturing industry are carried out to ensure that the final products are accurate in accordance with specifications. Generally, the measurement of such dimensions requires the measuring instrument to be in contact with the surface of the measuring object (contact measurement). Contact measurements may cause scratches on the measuring object. One solution to this problem is optical-based non-contact measurement using cameras. Some studies utilize reference objects in the process of converting pixels to units of length. The method requires that the reference object must always be present and appear on the image in every measurement activity. As a size standard, reference objects should not be used too often. Based on this, this study is directed to produce a non-contact measurement system with the use of reference objects only in calibration activities. This method uses the principle of laser scanner-based triangulation with an image processing method to obtain the size of the object based on the pixel coordinates of the laser beam that hits the surface of the object. The proposed system was then tested with measuring objects in the form of a ball with a diameter of 11.15 cm, a cube with a rib length of 2 cm, and a cylinder with a diameter of 8.2 cm and a height of 14 cm (based on the measurement results using a caliper). Measurements on these objects produced an average accuracy of 99.7% and an error value of 0.3%. The system can also be applied to measuring objects in the form of cylinders test weight in the field of metrology.

Abstract

The localizer at Perum LPPNPI Yogyakarta Branch uses the Normarc brand Type NM7013 with a working frequency of 109.1 MHz. One incident on September 12 2023, there was a report from the pilot stating that the signal from the Runway 09 localizer equipment received by the pilot was unstable. This research uses the fishbone diagram method and calculations and simulations of potential interference using dRSS, iRSS, and C/I parameters using SEAMCAT for predetermined distance samples. In addition, an analysis was carried out regarding the effect of interference on the localizer beam signal. The results of this research are that wild frequency interference with the localizer occurs at distances d3 (15 NM), d4 (20 NM), and d5 (25 NM). Meanwhile, interference does not occur at distance d1 (5 NM) and distance d2 (10 NM). The effect of this frequency interference is the disruption of the aircraft landing process at Adi Sutjipto Airport. To overcome these problems, air navigation service providers must ensure that the ILS system is properly maintained and protected from frequency interference.

Abstract

Cryptography is the science of information security which is the most fundamental basic issue in ensuring the security of data transmission via the web. Cryptography works by transforming data or information into random form. Video data is the most widely accessed information medium because video conveys information in audio and visual form. In this study, cryptography was carried out on AVI video files with a combination of Beaufort and Vigenere substitution cipher algorithms using the RC4 key generator. Testing was carried out on three groups of video sample test data based on the size of the video file, where each group contained 10 video files. The test results obtained an average time required for encryption of 17 minutes 17 seconds, decryption of 17 minutes 40 seconds. The quality is indicated by the algorithm, namely from data integrity with an MSE value of 0 and a PSNR value of infinte, from the resulting cipher having an average value of MSE ± 15883 and PSNR ± 0.612 dB on audio, and an average value of MSE ± 14173 and PSNR ± 0.674 dB on frames. Resolution and video file size as well as initial key length do not significantly affect MSE and PSNR values. Statistically, the frequency range of color appearance in the histogram of cipher frames becomes narrower and relatively uniform. Waves in the audio cipher against time units move irregularly with changing sound level amplitudes and are relatively uniform in each audio sample. The resistance of the cipher to attacks is proven by the audio in three groups giving an average MSE of ± 16074 and PSNR of ± 0.607 dB, while for frames in three groups giving an average MSE of ± 15941 and PSNR of ± 0.623 dB.
