In this paper, to analyze the transport of autonomous robots, an artificial Capital market is used. Capital market is considered as a pier which loading and unloading of cargo is done. Autonomous robots load and unload from the ship to the warehouse wharf or vice versa. All the robots have the ability of transporting the loads, but depending on loads and the location of unloading (or loading) a...

Robots are increasingly being used to solve real-world tasks such as vacuuming or assembly-line work in industrial applications. Controllers for these robots are typically designed by engineers following textbook guidelines. Although this methodology has proven to be very successful in such applications, it quickly meets its limitations as tasks become more complex. Collective robotic systems, ...

In this paper, a four-bar mechanism with two flexible links is proposed to be used in a micromechanical flying insect robot wing thorax design for stroke amplification. PZT5H and PZN-PT based unimorph actuators are utilized at the input link of the four-bar. The kinematics and dynamics of the proposed wing strcuture with two parallel four-bar mechanisms are analyzed, and DC forces generated at ...

this paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. the proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. as a result, the proposed controller is simple, fast response and superior to the torque c...

in this article a new and an accurate method for kinematic and dynamic analysis of a parallel robot 3prs and a hybrid robot (parallel and serial) 3prs-rrp are presented, which is based on the denavit-hartenberg transformation matrix algebra. first, basic properties of various kinds of robots are compared, and then the denavit-hartenberg parameters and their table are introduced. next, the metho...

David Lentink Department of Mechanical Engineering, Stanford University, USA E-mail: [email protected] The invention and deployment of small flying robots (drones) is beginning to influence our everyday lives. Their applications are frightening to some and exciting to others. From military surveillance, to city courier services, to near-future flying camera phones, this technology is bound ...

the kinematics and dynamics of two industrial cooperating robots are presented in this paper. the noc (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. the joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. to this end, minimizing the cr...

Inertially Actuated Jumping Robots (IAJR) provide a promising new means of locomotion. The difficulty IAJR is found in the hybrid nature ground contact/flying dynamics. Recent research studies our Systems Lab have provided family tree inertially actuated locomotion systems. proposed Tapping Robot most prompt member this tree. In paper, feedback linearization controller introduced to controllabi...

Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease.  It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...
