Ballistic Control for Biped Walking with Pneumatic Actuators
Walking is a complex behavior that emerges from interaction between the agent body and the terrain. To realize adaptive dynamic walking by an artificial agent, therefore, not only its body and control dynamics but also the dynamics of the terrain should be taken into account. This paper describes a biped walker with pneumatic actuators and a ballistic controller that only applies driving force ...
متن کاملDevelopment of a Rat Model of Graded Contusive Spinal Cord Injury Using a Pneumatic Impact Device
An animal model of spinal cord trauma is essential for understanding the injury mechanisms, cord regeneration, and to aid the development of new therapeutic modalities. This study focused on the development of a graded experimental contusion model for spinal cord injury (SCI) using a pneumatic impact device made in Korea. A contusive injury was made to the dorsal aspect of the cord. Three traum...
متن کاملDesign and Experimental Study of a Combined Pneumatic Plot Seed-metering Device for Cotton
This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...
متن کاملSimulation of Ballistic Impact on Composite Panels
Ballistic impact on composite panels is studied in this work both experimentally and computationally. The purpose was to develop computational methods to analyze a high speed jet engine fragment impacting on composite targets. 12 inch by 12 inch laminated panels with 8, 16, and 32 plies and the standard +-45, 0 /90 degree stacking sequences were considered. With the nominal ply thickness of 0.0...
متن کاملThe impact force in the ballistic oscillator
We determine the impact force generated by the projectile penetrating the body of the harmonic oscillator.We discuss the ballistic effect in connection with the Compton effect.
