  • Stresses Due to Motion and Gravity in Similar Engines

    This revised edition of Taylor's classic work on the internal-combustion engine incorporates changes and additions in engine design and control that have been brought on by the world petroleum crisis, the subsequent emphasis on fuel economy, and the legal restraints on air pollution.The fundamentals and the topical organization, however, remain the same. The analytic rather than merely descriptive treatment of actual engine cycles, the exhaustive studies of air capacity, heat flow, friction, and the effects of cylinder size, and the emphasis on application have been preserved. These are the basic qualities that have made Taylor's work indispensable to more than one generation of engineers and designers of internal-combustion engines, as well as to teachers and graduate students in the fields of power, internal-combustion engineering, and general machine design.Charles Fayette Taylor is Professor of Automotive Engineering Emeritus at MIT.

  • Walking and Running on Yielding and Fluidizing Ground

    We study the detailed locomotor mechanics of a small, lightweight robot (DynaRoACH, 10 cm, 25 g) which can move on a granular substrate of closely packed 3 mm diameter glass particles at speeds up to 50 cm/s (5 body length/s), approaching the performance of small, highperforming, desert- dwelling lizards. To reveal how the robot achieves this high performance, we use high speed imaging to capture kinematics, and develop a numerical multi- body simulation of the robot coupled to an experimentally validated discrete element method (DEM) simulation of the granular media. Average forward speeds measured in both experiment and simulation agreed well, and increased non- linearly with stride frequency, reflecting a change in the mode of propulsion. At low frequencies, the robot used a quasi-static "rotary walking" mode, in which the granular material yielded as the legs penetrated and then solidified once vertical force balance was achieved. At high frequencies, duty factor decreased below 0.5 and aerial phases occurred. The propulsion mechanism was qualitatively different: the robot ran rapidly by utilizing the speed- dependent fluid-like inertial response of the material. We also used our simulation tool to vary substrate parameters that were inconvenient to vary in experiment (e.g., granular particle friction) to test performance and reveal limits of stability of the robot. Using small robots as physical models, our study reveals a mechanism by which small animals can achieve high performance on granular substrates, which in return advances the design and control of small robots in deformable terrains.

  • VisionBased Objective Selection for Robust Ballistic Manipulation

    The use of visual measurement for high-speed and high-precision robotic tasks requires careful analysis of the fundamental properties of the sensing paradigms chosen. In this work we analyze the information generated by a state estimator for a target moving object that is to be intercepted by a robotic manipulator. Selection of potential interaction objectives is carried out through analysis of the data stream from the visual system. The underlying sensing problem is designed for a principally unstructured environment under fixed-camera visual measurement. The test domain is chosen to be ballistic manipulation of a sliding object on a low-friction planar surface: the air hockey problem.

  • Real-Time Inverse Dynamics Learning for Musculoskeletal Robots Based on Echo State Gaussian Process Regression

    A challenging topic in articulated robots is the control of redundantly many degrees of freedom with artificial muscles. Actuation with these devices is difficult to solve because of nonlinearities, delays and unknown parameters such as friction. Machine learning methods can be used to learn control of these systems, but are faced with the additional problem that the size of the search space prohibits full exploration in reasonable time. We propose a novel method that is able to learn control of redundant robot arms with artificial muscles online from scratch using only the position of the end effector, without using any joint positions, accelerations or an analytical model of the system or the environment. To learn in real time, we use the so called online "goal babbling" method to effectively reduce the search space, a recurrent neural network to represent the state of the robot arm, and novel online Gaussian processes for regression. With our approach, we achieve good performance on trajectory tracking tasks for the end effector of two very challenging systems: a simulated 6 DOF redundant arm with artificial muscles, and a 7 DOF robot arm with McKibben pneumatic artificial muscles. We also show that the combination of techniques we propose results in significantly improved performance over using the individual techniques alone.

  • Design for Joint Torque Sensors and Torque Feedback Control for Direct-Drive Arms

    In a direct-drive arm, motors are directly coupled to their arm linkages without reducers. This eliminates some defects of traditional gearing such as backlash, friction and deflection, and therefore enables the drive system to have improved control accuracy. The D.C. motors used for the direct-drive arm, however, have a significant amount of torque ripples and deadband, which limits the control accuracy, particularly for compliance and force control. In this paper, a method for the torque feedback control of a direct-drive joint is presented. The motor output torque is directly measured by a strain gage sensor built into the motor. It is found that closed loop torque control can compensate for the complicated nonlincaritics and improve the overall control accuracy. First, the design of the torque sensor is presented. The effect of the structural vibration mode which results from the insertion of the flexible torque sensor is analysed, and a design method to place the natural frequency of this mode far above the operating frequencies is shown. Torque feedback control using the sensor is discussed. The sensor design is verified experimentally, and the control performance using direct torque feedback is evaluated.

  • Road Condition Monitoring

    Common measurement principles involve in situ measurements, where sensors are embedded in the road surface, and remote sensing technologies using visual cameras and infrared (IR) sensors or cameras. Recent days, development of cooperative traffic systems has increased the expectations concerning automatic road friction measurement units. Automotive industry has been investigating chances to utilize the roadside friction data for adjusting car control functions (i.e., ADAS). This chapter will review the promising camera vision and the short???wave IR (SWIR) laser unit technology to provide friction estimation for road users. The laser system consists of two laser diodes emitting at wavelengths ??1???=???1323???nm and ??2???=???1566???nm, whereas the camera system operates in the near???IR (NIR) band 850???950???nm. The algorithms have been developed to identify condition of the road surface (dry, wet, snow, icy, etc.)

  • Modeling Biomedical Signal Generating Processes and Systems

    This chapter proposes mathematical models to represent the generation of biomedical signals and identifies the possible relationships between the mathematical models and the physiological and pathological processes and systems that generate the signals. It also explores the potential use of the model parameters in signal analysis, pattern recognition, and classification. The models provide a small number of parameters that characterize the signal and/or system of interest; the modeling approach is, therefore, useful in parametric analysis of signals and systems. As the number of parameters derived is usually much smaller than the number of signal samples, the modeling approach could also assist in data compression and compact representation of signals and related information. Pole-zero models could be used to view physiological systems as control systems. Pathological states may be derived or simulated by modifying the parameters of the related models. Models of signals and systems are also useful in the design and control of prostheses. A combination of mathematical modeling with electromechanical modeling can allow the inclusion of physical parameters, such as the diameter of a blood vessel, constriction due to plaque, stiffness due to stenosis, and friction coefficient.
