To think quantitatively about comovement, we specify the model of Section I. We use a CES production function for one final good. 42 Thus, we can solve the structure of this economy in closed form, and quantify its comovement. Our model differs in a series of small ways from 43 Its main virtue is that it is solvable in closed form, so that the mechanisms are fairly transparent.

This paper presents a computationally efficient method for the modeling of robot manipulators with flexible links and joints. This approach combines the Discrete Time Transfer Matrix Method with the Finite Segment Method, in which the flexible links are discretized by a number of rigid segments connected by torsion springs; and the flexibility of joints are modeled by torsion springs. The propo...

The omni-directional mobile robot with multi DOF, because the operation posture and operation accuracy of the manipulator can be better controlled in a narrow or crowded workplace compared with the general manipulator, is getting more interested in practical applications. The present problem is to improve its flexibility for operating multiple different targets. Target recognition with image pr...

Design issues, dynamic modeling, trajectory planning, and feedback control problems are presented for robot manipulators having components with mechanical flexibility, either concentrated at the joints or distributed along the links. The chapter is divided accordingly in two main parts. Similarities or differences between the two types of flexibility are pointed out wherever appropriate. For ro...

Abstract For industrial applications, truss robots can perform mutipleoperations, such as transporting objects and handling tools independently, but face the challenges of inconvenient disassembly non-recyclability. Therefore, a robot load-bearing module based on spatial bar structure is designed, which consists bars connectors. Ansys Workbench used for static analysis beam. The results show th...

The automated storage and retrieval systems (ASRS) are major material handling support that commonly used in the factories, distribution centers, warehousing, non-manufacturing environments. These robot-based increasingly applied centers of high demand e-commerce operations because their less space requirement, higher operational flexibility continuous ability to work thereby continuously produ...

gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. in this paper, a new robotic orthosis is presented for treadmill training. in the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...

Industrial robot manipulators have become an indispensable means of automation to increase flexibility and productivity. The ever increasing quality standards and new applications impose higher requirements on accuracy, reliability and performance. Due to the complex nonlinear robot dynamics, the design of robot controllers should include accurate dynamic robot models. Robot identification is a...
