	The Artificial Inchworm Study
		As an inchworm moves forward it has the opportunity to sense what is in front of it without having to commit to attaching to an inappropriate surface.
		The strength of an inchworm's attachment to a surface li es in the way its foot pads grip the material it is attempting to move over.
		In addition, the inchworm managed to maintain a firm grip on the surface at all times while the tracked vehicle displayed a tendency for the upper track to slip as the slope was increased.

	Peristaltic driver apparatus - Patent 5751090
		Inchworm motors and actuators are exemplified by the linear translating devices shown in U.S. Pat.
		actuators or motors, a shaft coaxial with a piezoelectric actuating cylinder is clamped and moved along the axis of the cylinder when a section of the piezoelectric actuator is extended.
		Thus, it is desirable to reduce the failure mode of cracking and arcing due to tensile stressing of the materials, thereby increasing the reliability and life of the apparatus.

	INS-EPICS-3: INGRID EPICS control - recMotor_v1.95
		The motor record can force its drive fields to agree with its readback fields, and it does so in a variety of circumstances (e.g., when the user tells a motor to stop, and when a limit switch is hit).
		Therefore, if you are driving the motor record's VAL or DVAL field with the output of another record, and you want that record always to contain the same value as the motor record, you must handle this behavior in the database.
		The motor is expected to accelerate from a stand-still to VBAS in one motor pulse.

	Inchworm Motor (Site not responding. Last check: 2007-10-16)
		The purpose of the inchworm motor is to provide a controlled means of coarse approach to bring the probe tip to within the range of the Z movement of the piezo.
		The movement of the inchworm motor can be controlled manually while the position of the probe tip is verified with an optical microscope.
		At ranges closer than can be verified optically, the approach control is managed by software which steps the motor and extends the piezo testing for current at the tip.

	Inchworm motor - Wikipedia, the free encyclopedia
		The inchworm motor is a device that uses piezoelectric actuators to move a shaft with nanometer precision.
		The inchworm motor uses three piezo-actuators connected together.
		If the expansion of the center actuator is precisely calibrated (and the two outer actuators do not slip) then the position of the shaft can be precisely controlled while having substantial travel distance.

		The prototype motor will be fabricated with the rotor serving as the active element with the wave traveling on both surfaces of the disk, that rotates the drive-shaft, thus doubling the driving element.
		Motors can be classified by their mode of operation (static or resonant), type of motion (rotary or linear) and shape of implementation (beam, rod, disk, etc.).
		The operation of solid state ultrasonic motors depends on friction at the interface between the moving and non-moving elements and therefore have limited duty cycle similar to brushless DC type motors.

		The focus of this research was to create a linear motor that could easily be packaged and still perform the same task of the current DC motor linear device.
		The desired overall objectives of the research is to create an incremental linear motor with the capability of moving loads up to one hundred pounds and produce a velocity well over one inch per second.
		The velocity of the motor was limited by the drive frequency that the amplifiers could produce.

	"Kinesin Walks Hand-over-Hand" Physics Research Highlights, University of Illinois at Urbana-Champaign
		Because similar motors are responsible for moving chromosomes during cell division, basic understanding of kinesin could inform development of cancer-fighting drugs that target the cancer cell's machinery for reproduction.
		The kinesin molecule consists of two motor units (analogous to feet) that are linked together to a common stalk that attaches to cargo to be transported.
		If the inchworm model were correct, then both feet should move only in 8-nm steps as the kinesin molecule's center of mass moves.

		The operating principle of these motors relies on the use of an ultrasonic vibration, which is created via the piezoelectric effect (at resonance in most cases), in order to generate vibration forces at the `stator/rotor' contact interface.
		The MAD is similar to piezoelectric driven inchworm motors with the exception that mechanically interlocking microridges replace the traditional frictional clamping mechanisms.
		The active part of the motor is the rotor, which is a 100 $mu@m thick ring vibrating in a flexural mode.

		Motor speeds that are expressed in revolutions per second (S, SBAK, and SBAS) are independent of changes to MRES or UREV.
		For those motor controllers that provide their own internal software travel limits (e.g., MM4000), the motor record will only allow the user to set dial travel limits (i.e., D[H/L]LM) that are within the controller's travel limit range, inclusively.
		This decision allows the motor record EGU field (and consequently, MRES) to be set to an application specific value (e.g., kV) that is not supported by the motor controller.

	HHMI News: Cell's Motor Is a Mountain Climber, Not an Inchworm
		Researchers have demonstrated that one of the most important molecular motors for moving cargo within the cell does so with the hand-over-hand motion of a mountain climber, rather than an inchworm-like motion.
		Since similar motors are responsible for moving chromosomes during cell division, basic understanding of kinesin could inform development of cancer-fighting drugs that target the cancer cells machinery for reproduction, said the researchers.
		Not all motors are going to move by this mechanism, but what is unique about myosin V and kinesin is that both are utilized in the cell for long distance cargo transport, said Vale.

		Ultrasonic rotary motors have the potential to meet this NASA need and they are developed as actuators for miniature telerobotic applications.
		These motors have emerged in commercial products but they need to be adapted for operation at the harsh space environments that include cryogenic temperatures and vacuum and also require effective analytical tools for the design of efficient motors.
		Step and repeat piezoelectric devices, such as inchworm motors, increase the power output of the actuators and have the potential to produce large forces and large displacements simultaneously.
