Physicists uncover a universal limit on timekeeping precision, proving that anything from heartbeats to ocean waves can be a ...

Abstract: For 3D walking control of a biped robot we analyze the dynamics of a 3D inverted pendulum in which motion is constrained to move along an arbitrarily defined plane. This analysis yields a ...

Abstract: The control, prototyping, and experimentation of rotor-based systems (aerial robotic platforms) were highlighted recently for rotation around pipes for inspection, measurement, and ...
