Abstract

This study presents an evaluation of the performance of the Left-Straight-Right-Back (LSRB) algorithm implemented in an autonomous obstacle-avoiding robot. The LSRB algorithm operates based on a fixed priority rule in pathfinding decisions: turn left, go straight, turn right, and finally perform a 180-degree turn if no paths are available. The robot is equipped with ultrasonic sensors and a servo motor to scan obstacles on the left and right sides, and utilizes an 8×8 dot matrix display to indicate its navigation status. Testing was conducted in a custom-built maze environment featuring branches, dead ends, and narrow paths to simulate real-world navigation scenarios. Performance evaluation parameters include travel time, number of maneuvers, and path accuracy. Experimental results show that the LSRB algorithm achieved 100% path completion accuracy across all test cases, with consistent travel time and efficient obstacle avoidance. The findings demonstrate that LSRB is a reliable and lightweight navigation strategy, particularly suitable for low-cost, microcontroller-based robots used in educational or semi-structured environments. Limitations regarding power supply stability and the absence of memory-based path tracking are also identified, offering opportunities for future improvements.   Keywords - Obstacle-Avoiding Robot, Robot Navigation, LSRB Algorithm, Ultrasonic Sensor

Abstract

The aim of this research is to explain: 1) The influence of work motivation on the performance of East Kutai Regency driving teachers, 2) The influence of self-efficacy on the performance of East Kutai Regency driving teachers, 3) The influence of resilience on the performance of East Kutai Regency driving teachers, 4) The influence of work motivation on the resilience of driving teachers in East Kutai Regency, 5) The influence of self-efficacy on the resilience of driving teachers in East Kutai Regency, 6) The indirect influence of work motivation on performance through the resilience of driving teachers in East Kutai Regency, and 7) The indirect influence of self-efficacy on the performance of driving teachers through resilience in East Kutai Regency. Type of quantitative research. The research population was school principals and driving teachers for Classes 5, 7 and 8 in East Kutai Regency. The sampling method used proportional sampling of 20 school principals and 51 teachers. Results Based on the results of the research and discussion, it can be concluded as follows: 1) Work motivation has a direct positive effect on the performance of teachers in East Kutai Regency. 2) Self-efficacy has a direct positive effect on the performance of East Kutai Regency driving teachers. 3) Teacher resilience has a direct positive effect on the performance of teachers in East Kutai Regency. 4) Work motivation has a direct positive effect on the resilience of teachers driving East Kutai Regency. 5) Self-efficacy has a direct positive effect on the resilience of teachers driving East Kutai Regency. 6) There is a significant influence between work motivation and performance through the resilience of driving teachers in East Kutai Regency. 7) There is a significant influence between self-efficacy on the performance of driving teachers through resilience in East Kutai Regency.
