  • In this paper, two types of novel planar Translational Parallel Manipulators (TPMs) by using parallelogram mechanism are conceived. One is made up of two Pa-P (Parallelogram-Prismatic) legs connecting the base to the moving platform. The other consists of two P-Pa legs, which is the kinematic inversion of the former. Since connecting links in a parallelogram mechanism are subject to only tensile/compressive load and all the heavy actuators are mounted at the base, the proposed manipulators can be applied for planar positioning/assembly tasks requiring high stiffness and high speed. The position, velocity, and statics are analyzed, and the design methodology using prescribed workspace and velocity transmission capability is presented. Finally, two types of prototype manipulators have been developed.

  • It is prescribed for the controls layout of agricultural tractors to offer a comfortable workspace in ISO 4253 as international standard. To export other country to the Korea agricultural tractor, it needs to come up to the nation standard. The objective of the study is to investigate for location of control operation of the Korea agricultural tractor after applying the ISO 4253, to know whether it suits or not the nation standards with the tractor of product and supply within the country. As the research result of Korea agricultural tractor, Controls position of them are few in zone of comfort which defined in ISO 4253 and escapes lots in the zone of reach.
