Elements of kinematics diagrams include the frame, which is the frame of reference for all the moving components, as well as links (kinematic pairs), and joints. Primary Joints include pins, sliders and other elements that allow pure rotation or pure linear motion. Higher order joints also exist that allow a combination of rotation or linear ...
Lionel, LLC is an American designer and importer of toy trains and model railroads that is headquartered in Concord, North Carolina.Its roots lie in the 1969 purchase of the Lionel product line from the Lionel Corporation by cereal conglomerate General Mills and subsequent purchase in 1986 by businessman Richard P. Kughn forming Lionel Trains, Inc. in 1986.
Kinematics is used in astrophysics to describe the motion of celestial bodies and collections of such bodies. In mechanical engineering, robotics, and biomechanics, [7] kinematics is used to describe the motion of systems composed of joined parts (multi-link systems) such as an engine, a robotic arm or the human skeleton.
Lionel Corporation was an American toy manufacturer and holding company of retailers that was founded in 1900 and operated for more than 120 years. It started as an electrical novelties company. Lionel specialized in various products throughout its existence. Toy trains and model railroads were its main claim to fame. [1]
A leg mechanism (walking mechanism) is a mechanical system designed to provide a propulsive force by intermittent frictional contact with the ground. This is in contrast with wheels or continuous tracks which are intended to maintain continuous frictional contact with the ground.
Jansen's linkage is an eight-bar leg mechanism that was invented by kinetic sculptor Theo Jansen. Klann linkage is a six-bar linkage that forms a leg mechanism; Toggle mechanisms are four-bar linkages that are dimensioned so that they can fold and lock. The toggle positions are determined by the colinearity of two of the moving links. [19]
These kinematic features of gait are integrated or coordinated in order to ensure a circular arc trajectory of the COM, as theory proposed as the 'compass gait (straight knee)'. The theory underlying the determinants run contrary to that of the 'inverted pendulum' theory with a static stance leg acting as a pendulum that prescribes an arc.
In classical mechanics, a kinematic pair is a connection between two physical objects that imposes constraints on their relative movement . German engineer Franz Reuleaux introduced the kinematic pair as a new approach to the study of machines [ 1 ] that provided an advance over the notion of elements consisting of simple machines .
