SUMMARY The dynamic modeling and trajectory following issues are addressed for mobile modular manipulators. Simulations are performed to validate the proposed algorithms. I. INTRODUCTION Usually, modular manipulators are mounted on a fixed base whose mobility is constrained. We attach a mobile platform to the bottom of the manipulator to increase workspace. In related research work, dynamic cha...

in present paper, a point to point optimal path is planned for a mobile manipulator with flexible links and joints. for this purpose, a perfect dynamic modeling is performed for mobile manipulators considering large deformation in links, shear effects, elastic joints, effect of gravitation, and non-holonomic constraints. to study large deformation of links, non-linear relation of displacement-s...

In the last several years, mobile manipulators have been increasingly utilized and developed from a theoretical viewpoint as well as for practical applications in space, underwater, construction and service environments. The work presented in this chapter deals with the problem of intelligent behaviour modelling and control of a mobile manipulator for the purpose of simultaneously following des...

This paper presents a novel force control scheme for redundant mobile manipulators. Based on a decoupled and linearized dynamic model for integrated mobile platform and on-board manipulator, robotic tasks involving both position and output force control are discussed. Take the advantage of the kinematic redundancy of mobile manipulators, explicit force and position control at the same task dire...

Optimal load of mobile robots, while carrying a load with predefined motion precision is an important consideration regarding their applications. In this paper a general formulation for finding maximum load carrying capacity of flexible joint mobile manipulators is presented. Meanwhile, overturning stability of the system and precision of the motion on the given end-effector trajectory are take...

In most autonomous mobile manipulator systems, the mobile platform is only used for transporting the manipulators between spatially distributed assembly stations. In general, the mobility of the platform can be exploited to enlarge the workspace of a manipulator system (with one or multiple arms) at a single assembly station. In this article various approaches to the cooperation of a mobile pla...

This paper addresses the synthesis problem of Jacobian inverse kinematics algorithms for stationary manipulators and mobile robots. Special attention is paid to the design of extended Jacobian algorithms that approximate the Jacobian pseudoinverse algorithm. Two approaches to the approximation problem are developed: one relies on variational calculus, the other is differential geometric. Exampl...

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...
