Line Follower Robot adalah sebuah robot otomatis yang dapat mengikuti garis yang dibuat dengan menggunakan bahan yang berwarna gelap (hitam) yang didukung oleh rangkain komponen elektronika yang dilengkapi dengan roda dan digerakan oleh motor. Pengendalian kecepatan sangat bergantung pada bata putaran dan pergesekan antara ban robot dengan lantainya. Robot tersebut dirancang untuk bernavigasi dan bergerak secara otomatis mengikuti sebuah alur garis yang dibuat. Untuk membaca garis, robot dilengkapi dengan sensor optik yang diletakkan diujung depan dari robot tersebut. Line Follower Robot ini memiliki jenis dan bentuk serta memiliki beberapa sistem penggerak dan pengendali sebagai pengatur kinerja yang beraneka ragam sesuai dengan kreatifita pembuatnya. Pada perancangan proyek line follower robot kali ini akan dibahas tentang pemisah warna benda dan dianalisi lebih dalam terhadap faktor suatu kecepatan robot dengan gerakan motor yang dikontrol oleh pengendali Prorportional Integral Derivative (PID) sehingga gerakan robot dapat dinamis sesuai dengan track yang akan diujikan.Line Follower Robot is an automated robot that can follow a line that is made using a dark -colored material (black) which is supported by a chain of electronics components are equipped with wheels and is moved by a motor. Speed control is very dependent on the brick and the friction between the tire rotation robot with the floor. The robot is designed to navigate and move automatically in response to a flow line made . To read the line, the robot is equipped with an optical sensor that is placed in front of the tip of the robot. Line Follower Robot has the type and shape and have some drive and control system as a regulator of diverse performance in accordance with the maker's creativity. In designing the project time line follower robot will be discussed on the object color separator and analyzed over a factor in the speed of movement of the robot with a motor that is controlled by the controller Proportional Integral Derivative (PID) so that the robot can move dynamical in accordance with a track that will be tested.

In order to reduce the costs of implementing the radial position control system of a three-phase bearingless machine with split winding, this article proposes a driving method that uses only two phases of the system instead of the three-phase traditional one. It reduces from six to four the number of inverter legs, drivers, sensors, and current controllers necessary to drive and control the system. To justify the proposal, this new power and control configuration was applied to a 250 W machine controlled by a digital signal processor (DSP). The results obtained demonstrated that it is possible to carry out the radial position control through two phases, without loss of performance in relation to the conventional three-phase drive and control system.

Dimensional Optimization

The proposed study presents an original concept for the design of a walking robot with a minimum number of motors. The robot has a simple design and control system, successfully moves by walking, avoids or overcomes obstacles using only two independently controlled motors. Described are basic geometric and kinematic dependencies related to its movement. It is proposed optimization of basic dimensions of the robot in order to reduce energy losses when moving on flat terrain. Developed and produced is a 3-D printed prototype of the robot. Simulation and experiments for overcoming an obstacle are presented. Trajectories and instantaneous velocities centers of links from the robot are experimentally determined. The phases of walking and the stages of overcoming an obstacle are described. The theoretical and experimental results are compared. The suggested dimensional optimization approaches to reduce energy loss and experimental determination of the instant center of rotation are also applicable to other walking robots.

Measurement And Control

This paper presents the composition and working principle of the hardware and software of the measurement and control system based on VeriStand and Simulink for a tracked model vehicle. The hardware of the system is composed of a CompactRIO controller and acquisition cards, torque/speed sensors and a gyroscope. The vehicle control logic model and data processing model are built in Matlab/Simulink. VeriStand is adopted to manage models and interact with people. The system can control motor speed on both sides of the vehicle and collect data such as sprocket torque and speed, vehicle attitude on real-time. At last, we test and verify the system can work successfully.
