Desain dan Uji Coba Sederhana Pada Obstacle Avoiding Robot Menggunakan Mikrokontroler Arduino

Pada tulisan ini membahas tentang desain, konstruksi dan kontrol robot penyeimbang diri dari obstacle avoiding robot roda dua. Rangkaian sistem terdiri dari sepasang motor DC dan papan mikrokontroler Arduino, dengan menggunakan sebuah sensor ping HC-SR04 yang merupakan sensor ultrasonik untuk mendeteksi jarak ke rintangan dan dari posisi robot berada. Hasil yang diperoleh dari uji coba menunjukkan nilai jarak terhadap nilai ping (ping number) tegak lurus, semakin bertambahnya jarak maka akan semakin tinggi waktu ping yang di hasilkan. Nilai jarak sensor ke objek dan waktu ping paling rendah yaitu 2 cm, dan 132 µS, dan yang paling tinggi dengan jarak 20 cm dengan waktu ping yaitu 1160 µS. Semakin jauh jarak obstacle maka waktu yang diperlukan sensor untuk mengirimkan kembali hasil deteksi juga lebih lama.  This paper discusses the design, construction and control of the self-balancing robot obstacle avoiding thetwo-wheeled robot. The system circuit consists of a pair of DC motors and an Arduino microcontroller board,using a HC-SR04 ping sensor which is an ultrasonic sensor to detect the distance to the obstacle and from wherethe located of the robot. The results obtained from the test show the value of distance to the ping value (pingnumber) perpendicular, the more the distance will increase the higher the ping time generated. The value of thesensor distance to the object and the lowest ping time is 2 cm, and 132 μS, and the highest with a distance of 20 cmwith a ping time of 1160 μS. The further the obstacle distance, the time it takes the sensor to send back thedetection result is also longer

A Simple Aerial Photogrammetric Mapping System Overview and Image Acquisition Using Unmanned Aerial Vehicles (UAVs)

Aerial photogrammetry is one of the Alternative technologies for more detailed data, real time, fast and cheaper. Nowadays, many photogrammetric mapping methods have used UAV / unmanned drones or drones to retrieve and record data from an object in the earth. The application of drones in the field of geospatial science today is in great demand because of its relatively easy operation and relatively affordable cost compared to satellite systems especially high - resolution satellite imagery.  This research aims to determine the stage or overview of data retrieval process with DJI Phantom 4 (multi - rotor quad - copter drone) with processing using third party software. This research also produces 2 - dimensional high resolution image data on the research area. Utilization of third party software (Agisoft PhotoScan) making it easier to acquire and process aerial photogrammetric data. The results of aerial photogrammetric recording with a flying altitude of 70 meters obtained high resolution images with a spatial resolution of 2 inches / pixels.&nbsp
