Automatic sketching of planar kinematic chains [PDF]

, 1994
In this paper an original method for the fully automatic sketching of planar kinematic chains is described. This procedure may ease the interpretation of the results obtained during the enumeration of complex multi-loop kinematic chains.

Flocking and formation control for a group of nonholonomic wheeled mobile robots

Cogent Engineering, 2023
The problem of flocking and formation of a group of nonholonomic wheeled mobile robot is addressed in this paper. Based on the cascade structure of the kinematic model, two kinematic controllers are proposed to achieve formation and flocking behaviors ...

Kinematics and dynamics of Jansen leg mechanism: A bond graph approach [PDF]

Simulation Modelling Practice and Theory, 2016
The Jansen mechanism is a one degree-of-freedom, planar, 12-link, leg mechanism that can be used in mobile robotic applications and in gait analysis. This paper presents the kinematics and dynamics of the Jansen leg mechanism. The forward kinematics, accomplished using circle intersection method, determines the trajectories of various points on the ...
