One of the potential implementations of mobile robots in mitigating the risk of communicable diseases is for delivering items and handling materials with no-human contact. In that scenario, mobile robots require the capability of performing simultaneous multi-object detection and distance estimation for dynamic exploration in a real-world environment. Some existing research papers have contributed to the development of object detection or distance estimation, separately. However, there is still a lack of studies on simultaneous multi-object detection and distance estimation for robot navigation, especially in terms of performance analysis of the integrated techniques. One of the most challenging issues of integrating multi-object detection and distance estimation is the validation and evaluation of the type of objects with their relevant estimated distance to the robot. For that reason, this research aims to analyze the mobile robot's sensing performance in integrated simultaneous multi-object detection and distance estimation during navigation scenarios. A depth camera of Intel RealSense D455 and a rotating LIDAR of Slamtec RPLidar A1M8 are utilized in the experiments. The result of experiments shows that the object detection algorithm using Mobilenet SSD V2 can perform an accuracy of 74%, with precision, recall, and F1-Score consecutively achieving 74,54%, 74,00%, and 74,22%. The multi-object distance estimator also performs satisfactory results with a low measurement average error of 10.3 cm for indoor experiments. The integrated multiobject detector and distance estimator system can work in a real-time mode of 30 FPS, thence significantly improving the navigation performance of the mobile robot.

In the current digital era, virtual reality (VR) technology is rapidly expanding across various fields, including education and cultural preservation. This technology offers immersive opportunities to explore and experience architectural spaces, promising increased understanding and learning motivation. Despite being relatively new in Indonesia, the application of VR has shown significant potential for education and cultural preservation through the implementation of a 3D virtual tour in Kampung Adat Pulo Garut. Therefore, this research aimed to develop VR media to enhance users' spatial experience and preserve the cultural values of Kampung Adat Pulo Garut through interactive learning. The method used was Research and Development (R&D) through the Multimedia Development Life Cycle (MDLC) model. The equipment used was LiDAR Scanner FJD Trion P1 Series, DJI Mavic Air 2S Drone, and Sony A6000 Camera. The method used included aerial and terrestrial mapping, 3D modeling, and the development of virtual environments through Unreal Engine. The developmental process included various stages, namely concept, design, material collection, compilation, testing, and distribution. The result showed an interactive 3D virtual tour of Kampung Adat Pulo Garut, called “Echoes of Tradition.” Unreal Engine was found to enable detailed visualization of traditional architecture and village environments with high accuracy and interactivity. The final product offered an immersive learning experience, enriching users' experience, and enabling digital preservation of cultural heritage. The next step, to get an overview of the research results, used a questionnaire as an instrument which was distributed to a total of 250 respondents. Furthermore, the potential implication of VR in education and cultural preservation was identified, guiding similar applications in the future. By improving accessibility and engagement in spatial and cultural learning, VR offered new avenues in education and cultu
