...Yonghua Xiong; Lei Tian; Tofael Ahamed; Bin Zhao In this article, the development of the Reconfigurable Data Acquisition Vehicle (R-DAV) that has a high performance as a wheeled mobile robot is presented. The R-DAV is designed to monitor and manage the growing status of bio-energy crops...

... from Classic authors have been reported in which it is possible to find several traces on what we propose. Then some possible ancient motors suitable to be installed into the helepolis are proposed: capstans, tread wheel motors like the ones used by the Greek-Roman cranes, and counterweight motors...

...Chin-Lung Huang; Zhang-Hua Fong The tooth profile error of a gear shaping cutter made by the lengthwise-reciprocating grinding process (LRGP) is usually corrected by modifying the grinding wheel profile. However, such grinding wheel modification cannot eliminate the twisting profile error along...

Finally, particular cases of planetary gearboxes and a gearbox with equal idler pinions are studied, with the conclusion that their application is appropriate...

...Yang-Zhi Chen; Qiang Hu; Lei-Hou Sun The space-curve meshing wheel (SCMW) is a novel mechanical transmission mechanism suitable for small devices. It operates on the principle of space-curve meshing, which is quite different from traditional gearing mechanisms based on the surface meshing principle...

... to explore the design space. The use of this method results in a robot that has higher mobility than a robot designed using engineering judgment. A simple kinematic controller that considers the effects of terrain unevenness via an estimate of the wheel-terrain contact angles is also presented. It is shown...

...Jing-Shan Zhao; Fulei Chu; Zhi-Jing Feng; Sheng Zhao This paper focuses on the synthesis of an independent suspension that can guide the wheel to track a straight line when moving up (jounce) and down (rebound). With displacement subgroups, it first synthesizes a rigid body guidance mechanism...

...Yang-zhi Chen; Liang Luo; Qiang Hu The space-curve meshing-wheel (SCMW) is a novel mechanical mechanism suitable for small devices. In this paper, a design formula of the contact ratio of SCMW is derived from the space-curve meshing equation, which has been established in previous studies...

... by the Isoform® with a straight cone grinding wheel is not accurate enough for high precision requirement. That is why the shaper cutter is used as a rough cutting tool for most cases. A third-order profile correction to the cone grinding wheel is proposed to increase the accuracy of the work gear profile...

...Carlo Gorla; Piermaria Davoli; Francesco Rosa; Claudio Longoni; Franco Chiozzi; Alessandro Samarani In this paper, a theoretical and experimental investigation on an innovative cycloidal speed reducer is presented. The typical cycloid drive has a planet wheel, the profile of which is the internal...

...Michèle Guingand; Didier Remond; Jean-Pierre de Vaujany This paper deals with face gear design. The goal is to propose a simple formula for predicting the width of the wheel as a function of the main design parameters. A specific software was used to achieve this goal. This numerical tool is able...

These ideal characteristics are guaranteed by the particular rigid guidance mechanism whose end effector only has one translation along an exact straight line. Structure of Peaucellier–Lipkin eight-link Linkage...

...Jean-Pierre de Vaujany; Michèle Guingand; Didier Remond Nowadays, the wheels of worm gears with a low module can be made of plastic; thus, classical modeling can no longer be used satisfactorily. The present paper describes an original method for studying the quasistatic loaded behavior of a worm...
