Biomolecular motors have inspired the design and construction of artificial nanoscale motors and machines based on nucleic acids, small molecules, and inorganic nanostructures. However, the high degree of sophistication and efficiency of biomolecular motors, as well as their specific biological function, derives from the complexity afforded by protein building blocks. Here, we discuss a novel b...

Nowadays, Permanent Magnet Synchronous Motors have been considered as one of the best ones used in industry due to their high efficiency, low torque ripples and well known dynamical operation. Indeed, it is expected that this type of motors can be used more frequently. In this paper, a special type of these motors, the surface mounted PM motor, is considered. After introducing the mathematical ...

Synthetic molecular motors can be fuelled by the hydrolysis or hybridization of DNA. Such motors can move autonomously and programmably, and long-range transport has been observed on linear tracks. It has also been shown that DNA systems can compute. Here, we report a synthetic DNA-based system that integrates long-range transport and information processing. We show that the path of a motor thr...

In this paper, a neural network model reference adaptive system speed observer is designed, which can be used in speed control of linear induction motors (LIMs). Dynamical equations of LIM have been considered accurate. In other words, the end effect and the electrical losses of the motor have been included in the motor equivalent circuit. Then equations of the reference model and adaptive mode...

In gliding assays, filaments are pulled by molecular motors that are immobilized on a solid surface. By varying the motor density on the surface, one can control the number N of motors that pull simultaneously on a single filament. Here, such gliding assays are studied theoretically using brownian (or Langevin) dynamics simulations and taking the local force balance between motors and filaments...

Actin-based cellular protrusions are an ubiquitous feature of cells, performing a variety of critical functions ranging from cell-cell communication to cell motility. The formation and maintenance of these protrusions relies on the transport of proteins via myosin motors, to the protrusion tip. While tip-directed motion leads to accumulation of motors (and their molecular cargo) at the protrusi...

Motor-driven intracellular transport is a complex phenomenon where multiple motor proteins simultaneously attached on to a cargo engage in pulling activity, often leading to tug-of-war, displaying bidirectional motion. However, most mathematical and computational models ignore the details of the motor-cargo interaction. A few studies have focused on more realistic models of cargo transport by i...

This paper describes recent precision positioning technology. First, recent precision positioning mechanisms are introduced. Although ball screw mechanisms are widely used in industrial machines, the use of linear motors and the development of planar motors recently increase. Several linear motor mechanisms show the acceleration higher than 10G. The linear motor mechanism developed in my group ...

Hollis The Robotics Institute, Carnegie Mellon University faquaid, [email protected] Abstract Planar linear motors (Sawyer motors) have been used in industry as open-loop stepping motors, but their robustness and versatility has been limite...

Integrated Precision 3-DOF Position Sensor for Planar Linear Motors Zack J. Butler, Alfred A. Rizzi, and Ralph L. Hollis The Robotics Institute, Carnegie Mellon University fzackb, arizzi, [email protected] Abstract Planar linear motors have been shown to be capable of fast accurate 2-DOF motions making them useful for assembly tasks. However, the lack of sensing capability has limited their a...
