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 ?s servo will move to position 0, 1500 ?s
at 90 and 2000 ?s 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 ?s. 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
