The purpose of this research was to investigate a new method and a new practice of engineering low-cost, actuatable mechanisms. This work investigates the theory and practice which are needed to lay a foundation for the design of actuated mechanisms that consist of discrete functional sheets. The various requirements of traditional, functional components are embodied in sheets, or layers, of material rather than in discrete components (e.g. actuators, links, gears, etc...). The functional layers are designed to be bonded together in a way that forms an actuatable mechanism. These compliant layered mechanisms, CLMs, consist of four layers: (1) a skeleton cut from a single sheet of material that provides structural elements and compliant amplification mechanisms, (2) actuation, (3) control circuitry, and (4) sensors or other functional components as needed. This thesis presents the design, modeling, fabrication, and experimental validation of the CLM concept. Precision machines with integrated stiffness characteristics, actuation, and control circuitry are realized through forming / folding the CLM sheet. The CLM is implemented in a five axis nano-manipulator capable of a range of hundreds of microns and a resolution of tens of nanometers. The CLM manipulator is modeled using a node/beam stiffness matrix in CoMeTTM. The performance of the manipulator and the accuracy of the model are verified through a series of experiments in which the manipulator is made to translate (Y and Z) and rotate (OX). The skeleton of the CLM utilizes thin elliptical compliant amplifier mechanisms (TECAs) to provide amplification and guidance of the actuators.
(cont.) The behavior of the TECA is shown to be governed by the transmission ratio (amplification) and the ratio of the width to thickness of the flexure elements. A parametric design tool was developed enabling designers to predict and control the performance of TECAs subjected to a combination of desired and undesired forces through optimization of these key ratios. The CLM offers advantages in applications beyond manipulation which currently require costly mechanisms based on discrete functional components. Two such applications are morphing structures such as the Smart Wing under development by NASA and DARPA [1], and energy transducing and damping mechanisms.

In this thesis, I designed and simulated an actuator mechanism for generating a moment within a compliant (soft) body system. The moment produces vibrational waves throughout a compliant material, and these vibrations are utilized to create biomimetic locomotion. The prototype actuator was developed for use in a fish tail, but it is hope that the actuation system can be applied in other robotic structures. The primary goals of this project included making gains in energy efficiency over previous embodiments, creating a compliant actuator that does not interfere with the natural body vibrations, and creating a system that can easily be modified to be used in a wide variety of soft-bodied systems. The system is also scalable to the size of the structure being actuated.

The objective of this research is to generate the knowledge required to adapt macro- and microscale compliant mechanism theory to design carbon nanotube-based nano-scale compliant mechanisms. Molecular simulations of a nano-scale parallel guiding mechanism uncovered three regions of behavior. Region I is governed by the bulk deformation of the carbon nanotubes. Region II is characterized by hinge-like flexing of four "kinks" that occur due to buckling of the carbon nanotube walls. Region III, an intermediate region, exhibits direction dependant behavior. We report on the ability of a conventional compliant mechanism modeling approach, the pseudo-rigid-body model, to predict the region I behavior of a nano-scale parallel guiding mechanism that uses single-walled (5,5) carbon nanotubes as the flexural elements. Van der Waals forces were found to affect the kinematic and elastomechanic behavior of the nano-scale parallel guiding mechanism. A modified value of the pseudo-rigid-body model stiffness coefficient is presented to capture the affect of van der Waals interactions within (5,5) nanotubes during region I operation.
(cont.) Molecular simulation of region I behaviors match the modified pseudo-rigid-body model predictions of (1) kinematic behavior with less than 7.3 % error and (2) elastomechanic behavior with less than 8 % error. Although region I is of the most interest because of its well-defined and stable nature, region II motion is also investigated to provide a basis for establishing future work in this region.

In this paper, the design and testing of an ankle rehabilitation device is presented. The purpose of the research done is to provide physicians with a diagnostics tool that can quantitatively measure the severity of an injury by measuring the ankle joint's functional output. Torque and power output have been shown to be correlated with functional performance of the ankle joint. The device can measure torque and power output over the full range of motion of the ankle joint complex. Such a device has the potential to enable more accurate diagnoses and improve the efficacy of treatment and rehabilitation. The device allows rotation about the three orthogonal axes in the Cartesian plane. The rotations are linked in series to simulate ankle subjoint coupling. Cartwheel flexures with strain gages are aligned with the rotational axes and used as torque sensors. Strain gages are placed in a Wheatstone bridge circuit to mitigate environmental factors. Trials measured torque of the right ankle joint of test subjects from a standing position. Results show that the coupling of the two modes of ankle joint rotation (plantarflexion/dorsiflexion and inversion/eversion) are dependent on a subject's own development.

This thesis documents the development of CoMeT, a conceptual evaluation and detailed synthesis aid for the design of compliant mechanisms. The vision behind CoMeT is making the limiting step in flexure design the speed of the user's imagination, not proficiency with software tools. Sophisticated kinematic analysis routines are seamlessly integrated into a three dimensional finite element program. A user may interface through both a convenient GUI and the powerful MATLAB command line. CoMeT's element models have been shown to generally lie within 3% of traditional FEA predictions. The experimentally determined response of a typical complex mechanism differed by less than 10%, and CoMeT proved to be just as accurate as conventional FEA. In a brief user interaction study, a subject with one hour of CoMeT training was able to perform a two-variable optimization in half the time it took with traditional software. Observations suggest that CoMeT encourages the conceptual thought and high-level insights that are the key to success in mechanism design.

The purpose of this thesis is to design an educational kit to be used to teach practicing engineers about recent developments in the study and design of flexures. Flexure theory can be difficult to explain. This kit is a physical example of the FACT method for designing flexures. The first flexure is a linear motion flexure, which is a familiar design to practicing precision engineers. The second design is a flexure which moves in a screw motion, which has never been built before. The design of the screw flexure uses the FACT method to combine constraints to create a linked linear and rotational motion. The screw flexure is also designed to have a variable pitch, such that it ranges from pure rotational motion to linear motion. This thesis contains the modeling, design, and fabrication process for both the linear and screw flexure. Two working prototypes were manufactured of each flexure. They are assembled on a baseplate and include sensors to measure the motion of each flexure. One kit was used to explain the concepts behind the design of the flexures to two students. They were then able to answer a few questions about the concepts after experimenting with the flexures.

The Precision Systems Design and Manufacturing Lab at the Massachusetts Institute of Technology has the need for a metal forming device capable of applying a plastic deformation to two-dimensional sheet metal templates of up to 1/8-inch thickness and 8-inch diameter in order to transform them into prototype three-dimensional monolithic compliant mechanisms. These mechanisms have applications in industrial positioning as they are highly accurate and free from normal performance reducers such as friction, wear, and backlash. This thesis presents the design of a prototyping press capable of achieving the deformation required to produce the 3DMCMs from their 2D templates. The prototyping press that is developed herein utilizes a multiple-piston, hydropneumatic cylinder to deliver up to 5,000 lbf over a 4-inch stroke. The press offers force sensing to within 10%, displacement sensing to within 0.005 inches, and rate control centered around a 6-inch per minute average rate. It is powered by a compressed air supply at up to 100 psi and motion is controlled by a single electrical solenoid shut-off valve.

The purpose of this research was to generate the knowledge required to design compliant mechanisms that (1) attenuate undesired small-motion angular vibrations in rotational power transmission systems and (2) preserve the desired transmission of large-motion torque/angle inputs. This thesis investigates the design of vibration attenuating compliant mechanisms that are directly integrated into the load path of rotational systems. These devices enable designers to attenuate the amplitude of undesirable vibrations while simultaneously optimizing the transmission of torque inputs. The design, modeling, fabrication and experimental validation of two Compliant Vibration Attenuator (CVA) concepts will be presented. The first device, the Small Amplitude Vibration Isolator (SAVI), is a non-linear compliant device that isolates a resonating or non-resonating rotational system from vibrations by acting as a mechanical lowpass filter. The second device, the Damping Vibration Link (DVL) utilizes compliance and damping to attenuate undesired vibrations due to resonance. A linear lumped parameter model was created in Matlab® to simulate the static and dynamic characteristics of rotational power transmission systems. This model enables one to determine the dynamic characteristics of a system for a given set of inputs, thereby making it possible to (1) understand the requirements for the CVA and (2) ascertain the effect of the CVA on the system. Finite-element simulations were conducted to verify an empirical, parametric model that describes the performance of a SAVI as a function of its stiffness parameters.
(cont.) Proof-of-concept prototypes were tested to verify performance predictions and to determine the practical issues related to implementation. The thesis concludes with a case study which demonstrates the effectiveness of a SAVI when integrated into the steering system of a light-duty pickup truck. The SAVI was shown to offer a 60% reduction in vibration amplitude by trading off 7 ms of delay in steering wheel-vehicle response.

The purpose of this thesis was to learn about creating an educational kit as a tool for teaching professional engineers in industry about the theory of Freedom and Constraint Topology (FACT), and the new types of flexures that can be designed using this process. The importance of this thesis lies in the benefits compliant mechanisms give to precision engineering. The impact, by improving the quality of designs capable by professional engineers by teaching them about using FACT to design flexures, will contribute to higher quality, more agile, and more reliable technology worldwide. The metrological systems designed for the kit were comprised of a system of sensors and data collection apparati to analyze the physical characteristics of a particular type of flexure known as a "screw flexure", a compliant mechanism that has a single degree of freedom with coupled translational and rotational motion. Using lead weights of V4 to 2 pounds and two Mitutoyo #ID-S1012E digital Dial Indicators, measurements were taken for the translational and rotational deflection of the screw flexure. The pitch of the screw flexure was found to be 10.512 in/rad, which was a 9.4% error from the expected value of 11.5 in/rad. The experimental setup was a successful tool for teaching FACT methodology in the specific case of the screw flexure.
