When a humanoid lifts a heavy object, or carries an object in a bag or a carriage, it needs to change the reference CoM(center of mass) and ZMP(Zero Moment Position) in order not to fall down. However, it is not natural to design a reference CoM and ZMP to lift or to carry an object every time. In this paper, objects held by a hand are considered as an augmented virtual link connected at the end of...
We have developed a Boltzmann equation solver for two-dimensional (2D) semiconductor devices based on the spherical harmonics expansion and the maximum entropy dissipation scheme for stabilization. The large system of equations is partitioned according to the order of the spherical harmonics and solved by a memory efficient blockwise Gauss-Seidel method. Results are presented for a 2D NPN Si bipolar...
Stable and effective enforcement of hard constraints is one of the crucial components in controlling physicsbased dynamic system. This paper presents a new implicit constraint enforcement technique that is stable over large time steps and does not require problem dependent adhoc parameters. The conventional explicit Baumgarte constraint stabilization confines the time step to be within a stability...
