Abstract

This study aims to analyze robotics simulation tools that can be used to support algorithm development in the robot modelling process. There are several simulation tools for robot algorithm modelling that are popularly used by robotics developers. This study focuses on analyzing the effectiveness based on the features of the Robot Operating System Development Studio (ROSDS) and MATLAB as a development simulation platform using the comparative method. The results of this study claim that ROSDS is more effective than MATLAB in terms supporting the development of robotics simulation because ROS is used as a middleware in ROSDS that connects the communication between the program with the robot, so that makes it easier for making robotics simulation and ROSDS is easier to access than MATLAB. The trial case study of developing trajectory algorithm in the robot arm was carried out in this research to support the statement above, and it worked out well.

Abstract

ABSTRACT:Covid-19 Pandemic has limited onsite learning that brings challenges in doing the practicum. One of the alternatives to facilitate students doing practicum from home is the Virtual Laboratory Handbook which guides students to do practicum simulation virtually. This research is qualitative research that aims at analyzing the needs of the Virtual Laboratory Handbook from teachers and students as the target readers. A Focus Group Discussion (FGD) was held to collect the data. The participants were ten teachers from vocational schools in Banten province. Some findings of the FGD suggest that Virtual Laboratory Handbook can be used to teach microcontrollers to students in vocational schools. However, the book needs to be revised because some needs of the target readers have to be fulfilled, namely the information about the functions of each component, program code terminologies, goals of the project, and conclusion. Besides, students also need easy and engaging access to the handbook. Therefore, further developing the Virtual Laboratory Handbook is expected to meet these needs and deliver them through gamification.ABSTRAK:Pandemi Covid-19 memberikan banyak batasan terhadap pembelajaran tatap muka yang menghambat siswa dalam melakukan praktikum.

Abstract

Since the Covid-19 outbreaks in Indonesia, the number of positive cases has continued to grow. Hospitals are at a very high risk of being the site of the spread of Covid-19, resulting in problems with the many cases of doctors and nurses who contracted Covid-19 from their patients. Therefore, a robot is needed to reduce direct contact between doctors and nurses with Covid-19 patients. The Faculty of Engineering, Unika Atma Jaya, in collaboration with Alumni of the Faculty of Engineering, has succeeded in making a robot to help doctors and nurses serve Covid-19 patients with mild and moderate symptoms, who are still able to carry out activities independently. The robot, named AtmaBot, was made to be handed over to the Atma Jaya Hospital. AtmaBot is equipped with a camera for video calls between doctors and nurses and patients, helping to reduce direct contact between doctors, nurses with patients. AtmaBot can also deliver food, drinks, medicine, and other equipment, controlled by remote control or laptop. The handover of AtmaBot has carried out at Campus 3 BSD, followed by training on its use. The training is carried out by using the lecture method and practicing how to operate the AtmaBot for doctors and nurses' representatives. The training participants are expected to become trainers for doctors and other nurses at Atma Jaya Hospital. With this training, AtmaBot is expected to help doctors and nurses in isolation rooms, reducing the risk of doctors and nurses being infected with Covid-19.ABSTRAK:Sejak kasus Covid-19 merebak di Indonesia, jumlah kasus positif masih terus bertambah setiap harinya.
