Quadruped Robot with Reduced Number of Actuators

Control for a Biped Robot with Minimal Number of Actuators

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...

Feasibility Study on Stability of Gait Patterns with Changeable Body Stiffness Using Pneumatic Actuators in a Quadruped Robot

In this study, an oscillator-type gait controller for a quadruped robot with antagonistic pairs of pneumatic actuators is proposed. And by using the controller, a feasibility study on the stability of gait patterns with changeable body stiffness is reported. The periodic motions of the legs are generated and controlled by an oscillator network with state resetting. This type of controller has r...

Study on Quadruped Walking Robot

Though development of a practical walking robot is not easy at all, walking robots have many practical advantages resulting from moving functions peculiar to this type of robots including excellent moving characteristics and working characteristics on uneven land. Paying special attention to the encouraging possibility of the walking robot, the authors have been continuing research and developm...

Development of a Biomimetic Quadruped Robot

This paper presents the design and prototype of a small quadruped robot whose walking motion is realized by two piezocomposite actuators. In the design, biomimetic ideas are employed to obtain the agility of motions and sustainability of a heavy load. The design of the robot legs is inspired by the leg configuration of insects, two joints (hip and knee) of the leg enable two basic motions, lift...
