Abstract

In modern era, advances in technology - advanced technology are very rapid, especially avionics technology, one of which is UAV (Unmanned Aerial Vehicle). Especially in helicopters or UAVs, Landing Gear is a foot frame that serves as a support for aircraft loads while at the Ground so that the aircraft is able to stand up. To design a Robotic Landing Gear system with this capability it takes a system approach algorithm that is near perfect, one of which is developing an algorithm from the previous system by adding a Robotic Landing Gear foot adjustment algorithm on a particular field so as to increase the Robotic Landing Gear's ability to recognize the terrain surface. In this study, using several tests that aim to identify several possibilities in the research of Robotic Landing Gear algorithms that have been developed include servo testing, testing of HC-SR04 sensors, limitwitch testing, testing of HC-TE13 Robotic Landing Gear Systems, Testing of Robotic Landing Main Algorithms Gear and testing the Robotic Landing Gear balancing system.PWM results as a servo input generated by a microcontroller, based on MG995 servo datasheet giving a PWM signal of 1000 μs servo will move to position 0, 1500 μs at 90 and 2000 μs is 180, but the experiments that have been done are not suitable and error, so the size of the PWM signal that approaches and corresponds to the servo angle movement is 2500 μs. When testing the ultrasonic sensor RLG HC TE13 operational automatic mode at a distance of 100 cm (1 meter) still works well, according to a predetermined distance and can be applied to the system. Provision of conditions by pressing on the mechanical limit switch causes a 5V flow voltage on the microcontroller input pin in the program known ON, when the mechanical conditions limit the switch is not compressed or open, the voltage is interrupted at the microcontroller input pin so that the conditions in the program are considered OFF
