Motion control technology is making its way into the unstructured world inhabited by humans. It allows development of applications beyond the structured environment of an industrial plant. Such applications of motion control technology require shifting focus to the models, control strategies and algorithms needed for systems to work, interact, and cooperate with humans or other artifacts in an unstructured environment. Real-world haptic interactions are becoming an important technology with potential application in many different fields like surgery, teleoperation, cooperative work, microsystems, and education. These developments are leading to numerous challenges that need to be solved in order to develop practical and competent systems that support the human operator, and are fault tolerant, safe, easy to use, and capable of adapting to long-term changes in the environment. This paper discusses a number of the emerging issues within motion control technology, including but not limited to new algorithms that allow concurrent force/position control, human-in-the loop control, control in functionally related systems and haptics over internet.

“…The integrations of piezoelectric actuators (PEAs) and flexure-based mechanisms have been widely utilized in nano-positioning and manipulations [1][2][3][4][5]. On the one hand, the shape of a PEA changes if charge or voltage is exerted, and thus generating sub-nanometer resolution actuation.…”

Flexure-based mechanisms are widely utilized in nano manipulations. The closed-form statics and dynamics modeling is difficult due to the complex topologies, the inevitable compliance of levers, the Hertzian contact interface, etc. This paper presents the closed-form modeling of an XY nano-manipulator consisting of statically indeterminate symmetric (SIS) structures using leaf and circular flexure hinges. Theoretical analysis reveals that the lever's compliance, the contact stiffness, and the load mass have significant influence on the static and dynamic performances of the system. Experiments are conducted to verify the effectiveness of the established models. If no piezoelectric actuator (PEA) is installed, the influence of the contact stiffness can be eliminated. Experimental results show that the estimation error on the output stiffness and first natural frequency can reach 2% and 1.7%, respectively. If PEAs are installed, the contact stiffness shows up in the models. As no effective method is currently available to measure or estimate the contact stiffness, it is impossible to precisely estimate the performance of the overall system. In this case, the established closed-form models can be utilized to calculate the bounds of the performance. The established closed-form models are widely applicable in the design and optimization of planar flexure-based mechanisms.Keywords: Flexure-based mechanism, Statically indeterminate structure, Dynamics, Lever mechanism, Piezoelectric actuator © The Author(s) 2018.

“…Over the past several decades, as one of the best solutions for the micro/nano operating problems in industry, such as nano-imprint, cell operation, scanning probe microscopes, high density data recording, optical instruments, measurement systems and micro/nano manipulations [1][2][3][4][5][6][7], a precision positioning system usually possesses a number of advantages such as high positioning accuracy, fast response speed, appropriate workspace, satisfactory stability and dynamic characteristics [8,9].It is mainly composed of three parts,namely, the actuation unit, guide mechanism and end-effector. The piezoelectric actuator (PEA) is the main type of actuator which is often used to drivea positioning mechanismbecause it offers the extremely fine resolution, quick response, large force generation, high electrical-mechanical power conversion efficiency and small volume.…”
