Ideally, one would design a manipulator to be as rigid as possible. However there may be some occasions when the manipulator will be flexible. This will occur when the manipulator is very long and lightweight. Traditional flexible manipulators are difficult to control. This is because the manipulator has a nonlinear position variant behavior. Unfortunately using a large gear reduction does not ...

In this paper, sliding mode tracking control and its chattering suppression method are investigated for flexible-joint robot manipulators with only state measurements of joint actuators. First, within the framework singular perturbation theory, objective system is decoupled into two typical aims a slow subsystem fast subsystem. Then, considering lumped uncertainties (including dynamics external...

We consider planning and control problems for underactuated manipulators, a special instance of mechanical systems having fewer input commands than degrees of freedom. This class includes robots with passive joints, elastic joints, or flexible links. Structural control properties are investigated, showing that manipulators with passive joints in the absence of gravity are the most difficult to ...

In this paper, a flexible robotic assembly system with decentralized architecture is presented. The system is designed to achieve high reconfigurability so that it can adapt to changes in manufacturing environment; a new robot can be easily installed to the system and execute assembly tasks immediately, together with other devices. For easier reconfiguration, a semi-automated calibration method...

This study investigates the development of a Fuzzy Logic Controller (FLC) for tracking sinusoidal wave trajectory and suppressing vibration Two Link Flexible Manipulator (TLFM). The TLFM was modeled using Lagrange's formalism Assumed Mode Method (AMM). A three-part apparatus consisting mathematical model, real-world TLFM, control software designed implemented. FLC applied to both simulated TLFM...
