Wheeled mobile rovers are being used in various missions for planetary surface exploration. In this paper a six-wheeled rover with rocker-bogie structure has been analyzed for planar case. The detailed kinematic model of the rover was built and the dynamic model was derived based on bond graph. The simulation studies were performed for obstacle climbing capability of the rover. It was observed ...

Mice carrying mutations of the gene encoding the ion pore of the P/Q calcium channel (Cacna1a) are an instance in which cerebellar dysfunction may be attributable to altered electrophysiology and thus provide an opportunity to study how neuronal intrinsic properties dictate signal processing in the ocular motor system. P/Q channel mutations can engender multiple effects at the single neuron, ci...

Ergonomic intervention in spraying operation can provide a reasonable basis for recommendation on operating methods and improvement in operation for more output and safety. Two commercially available sprayers namely knapsack sprayer and rocker sprayer were evaluated with nine male subjects for the study. Age, weight and height of the selected subjects are 30.33±1.93 years, 68.33±9.51 kg and 168...

History/Symptoms-Clinical exam features-Gait parameters-Radiographic features-Surgical technique-Evidence I. PATHOANATOMY-CLINICAL FEATURES: This is primarily a stance phase problem a. EQUINUS CONTRACTURE at the ankle because of a gastro-soleus contracture. b. Initial contact: mid foot or forefoot c. Collapse of the medial arch: i. Talus is in equinus, talo-navicular joint is subluxed ii. Os Ca...

The pedal mechanism of the sewing machine was measured and its structural data were obtained. essence motion a crank rocker mechanism, characteristics analyzed; After mapping components in CATIA software, adding constraints assembling, parametric model is formed, which lays foundation provides reference for simulation dynamic characteristic analysis hinge four-bar mechanism.

This is part two of the paper on conceptual design of an engine valve. The previous paper describes the background and the need of an engine valve for an internal combustion engine. The present state of the engine valve technology and the innovations incorporated in its design has been described. This paper presents the conceptualization of an innovative valve train aiming at lesser number of c...
