Abstract

SBS adalah skuter keseimbangan diri yang termasuk kendaraan pribadi roda dua. Diharapkan penelitian dan pengembangan self-balancing skuter dapat mengurangi kadar emisi di jalan raya akibat emisi nol. Jadi dampak dari pemanasan global melambat dan menjadi kendaraan baru yang nyaman dan praktis untuk keperluan umum. Penelitian ini untuk merancangbangun diri menyeimbangkan skuter sebagai alat transportasi. Lebih detail, penelitian ini bertujuan untuk merancang sistem kontrol self-balancing skuter, merancang, serta menguji diri menyeimbangkan skuter. Self-balancing skuter menggunakan dua motor DC sebagai aktuator dikendalikan melalui mindstrom lego nxt dan sensor gyroskop. Hasil yang diperoleh self-balancing desain skuter dengan dimensi 770 mm x 540 mm x 1.250 mm menggunakan stainlis baja bahan dan besi sebagai bahan dasar dan aduk dan Maxon DC motor, sensor, dan sopir selengkap mekanik dan elektronik. Sistem kontrol robot pada diri balancing skuter adalah loop tertutup.

Abstract

This study aims to find out/design and electronic wheelchair that can go up and down a slope, as an aid facility for people with disabilities and elderly people. The wheelchair uses a relay motor control program applied in a microcontroller controlling a DC Motor. This study is intended to inprove the writer’s skills in designing electric wheelchairs that can go up and down a slope. In terms of academic purpose, it is expected that this research can provide additional knowledge for students, especially the students of Mechanical Engineering Department, Faculty of Engineering, Hasanuddin University about wheelchair design that can be beneficial in increasing production through automation in the field of science and technology. The electric wheelchair is equipped with a microcontroller that can receive instructions from a mover stick. It also has a visual equipment that can facilitate the wheelchair user. The instruction from the mover stick will be directly sent because it is connected to the microcontroller by using a serial cable. The results reveal that the manual wheelchair stick / drive shaft driven directly by the user sends instructions to the microcontroller in accordance with the desired wheelchair movement.The signal will be forwarded to the driver that will drive the motor. In this system, the mover stick functions as a user interface connected to the control system. The control system consists of several electronic chains that function to control the electric wheelchair equipped with components of interface input/output and a driver as the actuator.

Abstract

This study aims to analyze the influence of rotation and temperature on the strength of welded joints (tensile strength and strain stress) from the result of friction welding using low carbon steel (St.42). The Friction welding process was carried out by varying the rotation (550 rpm, 1020 rpm and 1800 rpm) and temperature (750oC, 800oC and 850oC). The results of the friction welding were then examined to find out their connections strength. The initial data of this research were obtained through the testing of tensile stress and strain stress by using the tensile testing machine and the torsion testing machine. The data obtained from the tests were analyzed by using statistical methods of regression and ANOVA. The results reveal that the maximum tensile strength value ​​and the highest maximum strain stress occur at the rotation of 1800 rpm  and the temperature of 850oC. The values were: σmax = 403.80 N/mm2 and ד max = 365.89 N/mm2. The statistical analysis reveals that there is a relationship betwen the input variable X (rotation and temperature) and output  variable Y (tensile strength and strain stress)

Abstract

Omniwheels robot is a kind of mobile robot that can be moved to any direction, different cases than non-holonomic mobile robot. The advantage of omniwheels is shape of the wheel. Control method of this research is kinematic control. The derivation of such method is matrices velocities of omniwheels robot.Than, the control system was implemented to tracking trajectory problem. Still in the control system, it was choosing closed loop control for auto navigation problem. Finally, the robot also was used ultrasonic sensors for obstacle avoidance problem.

Abstract

Penelitian ini bertujuan untuk merancang bangun Omniwheels robot sebagai prototipe robot penjinak bom. Kelebihan hasil rancangan ini adalah robot dapat bergerak ke segala arah tanpa melakukan manuver terlebih dahulu. Selanjutnya menganalisis kinematika mobile roboti untuk navigasi omniwheels mobile robot sebagai prototipe robot penjinak bom. Omni Wheel robot dapat bergerak mengikuti jalur pada permukaan bidang datar dan mempertahankannya dengan memanfaatkan sensor cahaya, atau line follower sistem. Roda omni adalah roda khusus dimana selain roda inti juga terdapat roda kecil tambahan yang memiliki sumbu tegak lurus terhadap sumbu roda. Sehingga inti roda pada mobile robot ini bisa berputar pada sumbunya seperti roda normal. Hal ini disebabkan karena adanya tambahan roda kecil roda inti juga dapat bergerak sejajar dengan sumbunya. Metode experimen dilakukan dengan dua motor yang bergerak saat bergerak arah sumbu x serta dua motor yang lain yang berfungsi saat bergerak arah sumbu y. Penelitian ini berhasil membuat prototipe robot yang deikenal dengan omni wheel mobile robot. Adapun interface yang digunakan untuk mengendalikan motor omniwheel  adalah perangkat mikrokontroller ATmega 8535, alat ini berfungsi sebagai computer mini yang dapat melakukan eksekusi program kendali robot. Selanjutnya diletakkan 4 DOF (degree of freedom) manipulator pada omniwheels mobile robot untuk mengangkat sebuah benda yang mirip bom.
