Micro-aerial vehicles (MAV) and their promising applications – such as undetected surveillance or exploration of environments with little space for land-based maneuvers – are a well-known topic in the field of aerial robotics. Inspired by high maneuverability and agile flight of insects, over the past two decades a significant amount of effort has been dedicated to research on flapping-wing MAV...

1.1 Visual servoing for robotics applications Numerous advances in robotics have been inspired by reliable concepts of biological systems. Necessity for improvements has been recognized due to lack of sensory capabilities in robotic systems which make them unable to cope with challenges such as anonymous and changing workspace, undefined location, calibration errors, and different alternating c...

Background and Objectives: The cause and pathophysiology of rheumatoid arthritis has not been fully understood and an experimental model of this disease is essential for research on the problem. In this research study, establishment and histopathological changes of chronic arthritis due to intra-articula...

This paper presents a pronking controller for our six-legged robot RHex. Development of the controller begins with a passive-dynamics approach, ensuring that the robot is naturally suited to running. Running with flight phase is then achieved using only proprioceptive (joint angle sensing only) feedback for touchdown detection and for tracking fixed joint reference trajectories. Body pitch osci...

Sprayers are important tools in agriculture that usually moved on the field by tractor. Sprayers should distribute the constant rate of chemicals during various conditions encountered in the field. Unwanted vibrations of sprayer boom cause redaction of its life time and over doses and under doses of chemical sprayed on the field. Therefore, in this study a model of suspension system for rotatio...

Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...

Abstract: Robotic manipulators have been widely used in many arenas, when the robotic arm performs positioning, a traditional controller (e.g., a proportional-integral-derivative, PID controller) has the problem of not being able to compensate the payload variations. When the end-effector of the robotic arm grasps different payload masses as most applications require, the output of joint motion...

The ability to control a robot in both constrained and unconstrained situations is important. One way to do this is using a switching controller which uses a force controller for constrained space and a position controller for unconstrained space. This paper develops a switching controller for a single flexible link manipulator and provides experimental results for a motion from unconstrained t...

This thesis presents research work related to the impedance control of redundant manipulators. The main goal is to study the effects of redundancy on the dynamic behaviour of manipulators. Firstly, theoretical developments related to redundancy, dynamics and impedance control are presented in general form without restriction to any particular manipulator. The purpose is to keep the findings use...
