چکیده

This paper presents a novel unified theoretical framework for differential kinematics and dynamics for complex robot motion optimization. By introducing 18×18 comprehensive motion transformation matrix (CMTM), forward differential kinematics and dynamics including velocity and acceleration can be written in a simple chain product like ordinary rotational matrix. This formulation enables analytical computation of derivative of various physical quantities including joint force or torques with respect to joint coordinate variables and their derivatives for a robot trajectory in an efficient manner (O(NJ), where NJ is the number of the robot’s DOF), which is useful for motion optimization.

Dynamics of a Running Below-Knee Prosthesis Compared to Those of a Normal Subject

The normal human running has been simulated by two-dimensional biped model with 7 segments. Series of normal running experiments were performed and data of ground reaction forces measured by force plate was analyzed and was fitted to some Fourier series. The model is capable to simulate running for different ages and weights at different running speeds. A proportional derivative control algorit...
