چکیده

in this paper, finding dynamic load carrying capacity (dlcc) of flexible link manipulators in point to-point motion was formulated as an optimal control problem. the finite element method was employed for modelling and deriving the dynamic equations of the system. the study employed indirect solution of optimal control for system motion planning. due to offline nature of the method, many difficulties such system nonlinearities and all types of constraints can be catered for and implemented easily. the application of pontryagin’s minimum principle to this problem was resulted in a standard two-point boundary value problem (tpbvp), solved numerically. then, the formulation was developed to find the maximum payload and corresponding optimal path. the main advantage of the proposed method is that the various optimal trajectories can be obtained with different characteristics and different maximum payloads. therefore, the designer can select a suitable path among the numerous optimal paths. in order to verify the effectiveness of the method, a simulation study considering a two-link flexible manipulator was presented in details.

Maximum Allowable Dynamic Load of Flexible 2-Link Mobile Manipulators Using Finite Element Approach

In this paper a general formulation for finding the maximum allowable dynamic load (MADL) of flexible link mobile manipulators is presented. The main constraints used for the algorithm presented are the actuator torque capacity and the limited error bound for the end-effector during motion on the given trajectory. The precision constraint is taken into account with two boundary lines in plane w...

Dynamic Load Carrying Capacity of Mobile-Base Flexible-Link Manipulators: Feedback Linearization Control Approach

This paper focuses on the effects of closed- control on the calculation of the dynamic load carrying capacity (DLCC) for mobile-base flexible-link manipulators. In previously proposed methods in the literature of DLCC calculation in flexible robots, an open-loop control scheme is assumed, whereas in reality, robot control is achieved via closed loop approaches which could render the calculated ...

Determining Maximum Load Carrying Capacity of Flexible Link Manipulators

In this paper, an algorithm is proposed to improve the Maximum Load Carrying Capacity (MLCC) of exible robot manipulators. The maximum allowable load which can be achieved by a exible manipulator along a given trajectory is limited by the joints' actuator capacity and the end e ector accuracy constraint. In an open-loop approach, the end e ector deviation from the prede ned path is signi cant a...

Optimal Trajectory of Flexible Manipulator with Maximum Load Carrying Capacity

In this paper, a new formulation along with numerical solution for the problem of finding a point-to-point trajectory with maximum load carrying capacities for flexible manipulators is proposed. For rigid manipulators, the major limiting factor in determining the Dynamic Load Carrying Capacity (DLCC) is the joint actuator capacity. The flexibility exhibited by light weight robots or by robots o...
