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.

  • Impedance Source Multi-Leg Inverters

    Standalone distribution generation (DG) systems have recently received much attention for their advantages in supplying power to remote customers. To eliminate the drawbacks of the two-stage dc-dc converters and three-phase voltage source inverters (VSIs), this chapter examines the Z-source four-leg inverter, starting with an analysis of the unbalanced load, and the effects of an unbalanced load. Then, it introduces the different inverter topologies for mitigation of unbalanced conditions. The chapter presents impedance source multi-leg inverters, which consist of three-phase four-leg inverters and five- phase inverters. It investigates ZS/qZS three-phase four-leg inverters with a detailed mathematical model, switching schemes including SVPWM and carrier- based PWM. Then, to analyze buck and boost conversion modes of qZS four-leg inverter, experimental results were presented in different case studies. The chapter presents the qZS five-phase inverter with mathematical model and switching schemes including various SVPWM techniques.

  • State Estimation for Legged Robots: Consistent Fusion of Leg Kinematics and IMU

    This paper introduces a state estimation framework for legged robots that allows estimating the full pose of the robot without making any assumptions about the geometrical structure of its environment. This is achieved by means of an Observability Constrained Extended Kalman Filter that fuses kinematic encoder data with on-board IMU measurements. By including the absolute position of all footholds into the filter state, simple model equations can be formulated which accurately capture the uncertainties associated with the intermittent ground contacts. The resulting filter simultaneously estimates the position of all footholds and the pose of the main body. In the algorithmic formulation, special attention is paid to the consistency of the linearized filter: it maintains the same observability properties as the nonlinear system, which is a prerequisite for accurate state estimation. The presented approach is implemented in simulation and validated experimentally on an actual quadrupedal robot.

  • Adaptive leg placement strategies in the fruit fly set an example for six-legged walking systems

    Poster. Leg placement of the fruit fly Drosophila melanogaster was studied under various visual conditions while walking on a square-wave like linear array of narrow "stepping stones". Three-dimensional high speed video analysis revealed elaborate and error tolerant trajectories of the different legs which depend only to a minor extent on visual influences. Flies do not endeavor to place their legs always on the top surfaces of the treads but equally often cling to the edges or to the side surfaces of the stepping stones. A successful fly-like walking robot would rely on visual influences only for far-field orientation but would exploit a rich mechanosensation at its lower extremities and the ability to attach its legs to various surfaces. Technical solutions for these requirements are currently investigated using a single-leg test stand and a six-legged robot

  • 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.
