چکیده
We propose an automatically deployable robust control scheme for modular reconfigurable robot manipulators, which accounts noisy velocity measurements, yet it maximizes the tracking performance while avoiding chattering effects. Our proposed approach adapts to any of possible compositions given sets modules. The stability is guaranteed by exploiting use a recursive Newton-Euler with interval arithmetic computations. Moreover, maximized via online regulation parameters analyzing power spectral density commanded torque signal. Being fully automatic, allows quick deployment and reconfiguration manipulators. algorithm validated simulations experiments on commercially available robot.

Robust Hybrid Motion Force Control Algorithm for Robot Manipulators
In this paper we present a robust hybrid motion/force controller for rigid robot manipulators. The main contribution of this paper is that the proposed hybrid control system is able to accomplish motion objectives in free directions and force objectives in constrained directions under parametric uncertainty both in robot dynamics and stiffness constraint constant. Also, the given scheme is prov...
متن کاملInteractive-motion control of modular reconfigurable manipulators
─ A joystick-based interactive motion control approach is proposed for modular reconfigurable manipulators. Based on the product-of-exponentials (POE) formula, the velocity models as well as the incremental displacement models have been formulated for both serial manipulators (with arbitrary configurations and DOFs) and a class of three-legged parallel manipulators. As a result, two different c...
متن کاملModular Robot Manipulators with Precision Control
Modular robot manipulators have many advantages over conventional integrated robot manipulators, including flexibility, re-configurability, versatility, and low-cost with massive production. However, the lack of control precision has been a long standing drawback in MRM applications until now. In this paper, a VDC-based control and communication system using embedded FPGA (field programmable ga...
متن کاملDecentralized robust control of robot manipulators with harmonic drive transmission and application to modular and reconfigurable serial arms
In this paper, we propose a decentralized robust control algorithm for modular and reconfigurable robots (MRRs) based on Lyapunov’s stability analysis and backstepping techniques. In using decentralized control schemes with robot manipulators, each joint is considered as an independent subsystem, and the dynamical effects from the other links and joints are treated as disturbance. However, ther...
متن کاملDiscrete time robust control of robot manipulators in the task space using adaptive fuzzy estimator
This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...
