Optimal 5R parallel leg design for quadruped robot gait cycle

Compliant Leg Design for a Quadruped Robot

malian animals, i.e. that of a cat. It was also influenced by the spring-mass model representation [2]. Compliant prismatic legs show an intrinsic robustness for their angle of attack [2], they have a stability region. If the leg design is changed into a two segmented leg with a specific linear torsional spring, the leg stiffness kleg becomes nonlinear (Fig. 2(b) blue line), similar to that of ...

Effect of Leg Design on Locomotion Stability for Quadruped Robot

Locomotion Gait Optimization for a Quadruped Robot

Legged robot gait generation is a challenging task that involves the control of a large number of degrees of freedom (DOF’s) within a mechanical structure that varies during locomotion. A large number of motion parameters have to be considered in order to obtain a stable, natural and efficient locomotion. Legged robot locomotion applies nonlinear dynamical equations of high order with a multidi...

Gait Adaptation in a Quadruped Robot

Quadruped Robot Running With a Bounding Gait

Scout II, an autonomous four-legged robot with only one actuator per compliant leg is described. We demonstrate the need to model the actuators and the power source of the robot system carefully in order to obtain experimentally valid models for simulation and analysis. We describe a new, simple running controller that requires minimal task level feedback, yet achieves reliable and fast running...
