Abstract

Planning the path is one of the most important things in the world of robotics, especially autonomous robots, to be able to move the autonomous robot requires a path that will guide the movement, or steps to be taken next, can also be spelled out as the determination of the point of coordinates to be addressed so that the robot can move to destination by taking the nearest lane and guiding the robot not to take unnecessary steps. This research uses adaptive A-star algorithm as the shortest path finding algorithm, the algorithm used is the development of A-star algorithm so that it can perform path search gradually and done repeatedly to determine every step that must be taken robot in the future and this algorithm belongs to a simple algorithm in a family heuristic algorithm. The test environment is built using Netlogo 5.3.1 Application, an agent-based application developed by Uri Wilensky at the center for Connected Learning and Compute-based Modeling at Northwestern University. The results of the tests have shown that the adaptive A-star algorithm can perform the optimal shortest path search and not trapped in the optimal local conditions with a standard deviation of 0.422%.

Abstract

The DC motor is one component of robot, the main function of a DC motor is as a driver, whether its a legged robot or not, as used in a mobile robot. DC motor control is necessary to be one thing that must be considered, because if the motor does not run properly, it will renew the purpose of the motor when it is created. The ability to control a DC motor is needed when building a robot. Many things can affect a person’s ability to design DC motor controller, one of which is the development of science, especially computer science, the use of algorithms to achieve the effectiveness of DC motor movements is very necessary today, so that the robot can move well and according to what is desired. The algorithm requires some information from the system that is built either as input or output so that the algorithm can perform the control process properly. in this study the motor speed controller circuit has been designed using transistor IR630 (n-channel mosfet), in this study the motor speed controller circuit has been designed using transistor IR630 (n-channel mosfet), the potentiometer is used as an analog input on the microcontroller and then converted to a PWM signal which will be used as input to the controller circuit to drive a DC motor. In the tests that have been carried out, the results obtained that the motor can be controlled properly, the use of resistors with a certain amount (220 ohms) can increase the resulting motor rotation and at what voltage the motor starts to spin at a voltage of 0.436 volts, and continues to increase and the maximum voltage recorded at 6.40 Volts.

Abstract

Dalam situasi pandemic covid 19 seperti sekarang ini kami berfikir, bagaimana meningkatkan kesejahteraan UMKM pada bisnis Donat Mini (Domi) dengan tetap mematuhi protokol kesehatan. Maka kami membuatkan aplikasi E-Commerce dimana pemasaran akan dilakukan secara online. Dengan adanya sistem aplikasi E-Commerce ini nantinya akan memudahkan UMKM Domi dan masyarakat untuk tetap bisa melakukan transaksi jual-beli tanpa harus bertatap muka dan berkerumun antri di toko. Dengan begitu protokol kesehatan dapat dijaga untuk menjaga jarak dan kebutuhan konsumen terpenuhi. Aplikasi E-Commerce ini memiliki berbagai fitur fungsi utama antara lain adalah memberikan layanan teknis, informasi, dan promosi tentang jenis usaha yang diperjualkan kepada masyarakat. Aplikasi E-Commerce ini juga menjadi jembatan bagi masyarakat sebagai pemanfaatan teknologi dalam memenuhi kebutuhan.
