ABSTRACT Quadcopter in the development of robotics technology today is very often used in research. But the result of human error often damage in flight. The automated system needs t be created for the quadcopter in order to avoid an obstacle to minimize the damage. So the system remote control needs to be relaced so that it can do this automatically without human control. One of the sensors that can detect obstacle are ultrasonic sensors. These sensors use ultrasonic waves to measure the distance of something in front. When the ultrasonic sensor detects the presence of obstacle in front of the sensor will tell the quadcopter using MikroAVR 16, then quadcopter will do the calculations to quit then choose which path have no obstructions or obstacles. Sensor installed in four places on the quad copters is in the front, right, left, and rear in order to detect in various directions of the quadcopter. This substitute remote control system can detect obstacles in front, left, and I his right using ultrasonic sensor to measure distance and obstacles in set of centimeter. To be flown stably, must using quadcopter larger or using smaller microcontroller, so the quadcopter can fly stably and no distruption of the aerodynamics of the quadcopter. To detect obstacles even more reliable, can be used a tool Microsoft Kinect sensor. Keywords: Ultrasonic sensors, MikroAVR16, and Quadcopter
