Leg

View this topic in
A leg is a weight bearing and locomotive structure, usually having a columnar shape. During locomotion, legs function as "extensible struts" - the combination of movements at all joints can be modeled as a single, linear element capable of changing length and rotating about an omnidirectional "hip" joint.

  • SINGLE-PHASE TO SINGLE-PHASE BACK-TO-BACK CONVERTER

    Single-phase two-stage energy conversion systems are considered in this chapter. Such conversion systems, also known as back-to-back converters, deal with rectification and inversion through a direct link (dc)-link capacitor. This chapter describes the full-bridge topology for single-phase ac-dc-ac conversion. In addition to the model, pulse width modulation (PWM), and control strategies, a power analysis and an expression for the dc-link capacitor oscillation are also presented in the chapter. The chapter deals with nonconventional topologies, that is, topologies with reduced and increased number of power semiconductor devices. Semiconductor component count reduction is obtained by either sharing a leg or by using the dc-link mid- point connection. Topologies with increased number of components are addressed by connecting back-to-back converters both in parallel and series. This will allow THD improvements and reducing power processed by each converter.

  • Muscle Coordination, Motor Synergies, and Primitives from Surface EMG

    To investigate neural control strategies, muscle activity must be measured during motor behavior. Recent advances in the investigation of the neural control of movement have led to a re-examination of the mechanisms of sensorimotor integration in the central nervous system (CNS) and in the spinal circuitry in particular. This chapter considers different approaches used to uncover the modular organization of the motor output in human behaviors such as responding to postural perturbations, reaching with the arm, and locomotion, as well as its plasticity and flexibility in movement disorders. It also investigates the strategies that the CNS employs to coordinate the activation of many muscles start from electromyographic (EMG) signals recorded simultaneously from many muscles. Different muscle synergies models are used to decompose the EMG envelopes using appropriate factorization algorithms. The chapter further considers the spatiotemporal organization of the activity patterns of leg and trunk muscles during locomotion.

  • Three-Phase to Three-Phase and other Back-to-Back Converters

    A three-phase back-to-back converter is an important electrical apparatus with a wide range of applications on systems demanding a processed three-phase voltage. This chapter deals with the full-bridge ac-dc-ac converter presenting its model, pulse width modulation (PWM), and control strategies. Topologies with component count reduction are presented. The chapter describes the model, PWM, and control for configurations with an increased number of semiconductor devices. A similar approach as employed for the three-phase back-to-back converters, that is, shared-leg and dc-link capacitor midpoint connections for reducing the number of semiconductor devices, while connecting back-to-back converters in parallel and series are considered, respectively. The chapter discusses other converters, especially for single-phase to three-phase conversion and for a six-phase motor drive system.

  • Coordination of Leg Movement in Walking Animals

    When a robot has to move in a locally uncertain environment, propulsion by means of walking legs is advantageous compared to a wheel driven system. However, the control of walking legs is more complicated. The question of how the movement of the different legs is coordinated will be investigated here. Three different solutions which have been developed during natural evolution will be compared. These are the walking systems of an insect, of a crustacea, and of a mammal. The results show that coordinating mechanisms differ considerably in these animals.

  • Development of a Testbed for Robotic Neuromuscular Controllers

    Current control approaches to robotic legged locomotion rely on centralized planning and tracking or motion pattern matching. Central control is not available to robotic assistive devices that integrate with humans, and matching predefined patterns severely limits user dexterity. By contrast, biological systems show substantial legged dexterity even when their central nervous system is severed from their spinal cord, indicating that neuromuscular feedback controls can be harnessed to encode stability, adaptability, and maneuverability into legged systems. Here we present the initial steps to develop a robotic gait testbed that can implement and verify neuromuscular controls for robotic assistive devices. The initial stage consists of an antagonistically actuated two segment leg with a floating compliant joint. We detail its electromechanical design and low level, velocity-based torque control. Additionally, we present experiments that test the leg's performance during human-like high fidelity motions. The results show that the robot can track fast motions corresponding to 87% of the maximum performance limit of human muscle. The experiments also reveal limitations of our current implementation and we discuss solutions to overcoming them.
