Joint flexibility is a very important factor to consider in the controller design for robot manipulators if high performance is expected. Most of the research works on control of flexible-joint robots in literature have ignored the actuator dynamics to avoid complexity in controller design. The problem of designing nonlinear controller for a class of single-link flexible-joint robot manipulator...
In this paper, an ANFIS+PID hybrid control policy has been addressed to control a 6-degree-of freedom (6-DOF) robotic manipulator. Then its error convergence has been also evaluated. The ability to formulate and estimate the system uncertainties and disturbances along with system dynamics and rejecting the disturbances effect are some advantages of the proposed method in comparing with the co...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
موضوع این پایان نامه شامل طراحی و ساخت یک بازوی مکانیکی روباتیک به عنوان یک setup آزمایشگاهی مناسب برای مقایسه تجربی الگوریتم های کنترلی میباشد که در مقطع کارشناسی ارشد به انجام رسیده است. فصل اول این پایان نامه به بررسی و تعریف صورت مساله و اهداف آن میپردازد. در فصل دوم به بررسی و تشریح روابط سینماتیکی و دینامیکی بازوهای روباتیک پرداخته شده است و فصل سوم شامل بخشهای مربوط به طراحی و ساخت بازوی...
the suspension system of a vehicle is one of the most important parts which is involved in the process of vehicle designing. when a vehicle suspension system is designed, the evaluation of its performance against the road disturbances such as shocks and bumps are very important. the most commonly used systems consist of four hydraulic jacks with mobility in vertical line with low speed and low ...
In this paper, a control system is designed for automatic car turning. At first, the necessary information of car turning that were collected from the traffic bylaw, car driving training centers and traffic police are explained. Then, car turning is studied experimentally on several streets with different widths. Afterward, a proper path is designed for the automatic car turning system consider...

This paper presents designing an optimal adaptive controller for tracking control of robot manipulators based on particle swarm optimization (PSO) algorithm. PSO algorithm has been employed to optimize parameters of the controller and hence to minimize the integral square of errors (ISE) as a performance criteria. In this paper, an improved PSO using logic is proposed to increase the convergenc...
as a robot could be stable statically standing on three or more legs, a six legged walking robot can be highly flexible in movements and perform different missions without dealing with serious kinematic and dynamic problems. an experimental six legged walking robot with 18 degrees of freedom is studied and built in this paper. the kinematic and gait analysis formulations are demonstrated by an e...
