Abstract

Today, the mapping and navigation systems are increasingly sophisticated, especially in detection systems. Detection system was become an important thing that could be very useful to be implemented in various fields such as searching system, exploration, military and also in the industrial sector. Detector system works using proximity sensor that can collect many environmental information by detecting objects around them. Recently, Light Detection and Ranging (LIDAR) is one of the most popular tools for detecting object. The capability of LIDAR to detecting an object is very powerful. However, since the price of LIDAR sensor is very expensive, some researchers try to solve this issue. This study proposed a prototype system for object detection based on coordinates using RP LIDAR concept which is low cost. The prototype combined the HCSR04 ultrasonic sensor with a 360-degree continuous servo motor to build a detector system. The ultrasonic sensor is use for determined the distance and works by receiving a reflected wave from the transmitter, while the continuous servo motor is used for rotate the ultrasonic sensor, so that it can rotate 360 degrees according to the angle rotation. We do testing the performance of this prototype by using cartesian board with scenario that we set the prototype in the zero-degree position and the detection object in quadrants 1, 2, 3, 4 within a distance 5 cm - 50 cm. The result show that this prototype can detect the object coordinate with average error for x-axis is 1.178 cm and the y-axis is 1.2875 cm. This result means that the prototype was quite properly good to detect object coordinate.
