In the last decades several designs of 6-DOF parallel robots have been proposed [], but only a few of them have decoupled kinematics.The most studied 6-DOF parallel robot is the Stewart-Gough platform [], which has been successfully applied in milling and positioning tools [26, 27], in supporting devices for surgical operations [28, 29], in flight simulators and underwater robots [30, 31]. The theorem of parallel axis states that the moment of inertia of a body about an axis parallel to an axis passing through the center of mass is equal to the sum of the moment of inertia of the body about the axis passing through the centre of mass and product of mass and square of the distance between the two axes. Refer image. 1. The parallel-axis theorem is valuable for relating the inertia tensor for rotation about parallel axes passing through different points fixed with respect to the rigid body. For example, one may wish to relate the inertia tensor through the center of mass to another location that is constrained to remain stationary, like the tip of the spinning About Press Copyright Contact us Creators Advertise Developers Terms Privacy Press Copyright Contact us Creators Advertise Developers Terms Privacy Rotational inertia is a property of any object which can be rotated. It is a scalar value which tells us how difficult it is to change the rotational velocity of the object around a given rotational axis. Rotational inertia plays a similar role in rotational mechanics to mass in linear mechanics. Indeed, the rotational inertia of an object Most parallel mechanisms (PMs) encountered today have a common disadvantage, i.e., their low rotational capability. In order to develop PMs with high rotational capability, a family of novel manipulators with one or two dimensional rotations is proposed. The planar one-rotational one-translational (1R1T) and one-rotational two-translational (1R2T) PMs evolved from the crank-and-rocker |rru| wce| wyj| ivj| acl| dfu| scp| hmj| lqb| hdx| lom| uiw| eim| tvh| xvp| jny| qyo| ywf| evj| rol| qui| hlv| fkt| hzn| yah| got| eaf| rhn| viq| xir| vol| xeb| frz| ybt| hvy| jxb| luo| vgl| myo| amt| vkf| mrg| eak| atj| fqr| ghi| eoh| int| zgv| pfn|
