Abstract

Photography studios often require various lighting arrangements for different photo and video shooting themes. Lighting in a studio environment is critical to producing high-quality images and videos. However, conventional lighting sources, such as lamps or other lighting equipment, are often inflexible to reposition according to the photographer’s desired thematic setup. Manual lighting adjustments can be time-consuming, mainly when automated positioning features are unavailable. This inefficiency hampers the photo and video shooting process. In the community service program discussed in this article, the team from the Mechanical Engineering Department at Atma Jaya Catholic University of Indonesia developed a motorized stepper-based lighting system with railing to address the inefficiencies in studio lighting adjustments. The team partnered with Kolaborasi Berkat Kreasindo (KBK) studio. The developed lighting system can be controlled remotely, eliminating the need for direct manual adjustments. This solution has assisted the partner studio in enhancing the lighting setups for photography sessions.

Abstract

The path planning module is essential for the navigation of autonomous systems. This research aims to develop a path-planning module in Python programming language using the A* algorithm in conjunction with V-REP software which is used to simulate the path-planning outcome. The A* algorithm is used in this research to implement path-planning for a tricycle mobile robot. Both simulated and physical studies were performed to evaluate the module's performance. In the experiments, inputs of velocity and steering angle are given to the mobile robot at every period as obtained from the simulation regression. The discrepancy between the simulated and physical experimental results was attributed to the inertia force acting on the robot and other factors. The steering angle dominance on a mobile robot also affects the final position of the robot.
