The problem of control for group of pendulums is considered. Control goal is the synchronization of several remote pendulums over Internet. Some theoretical approach is presented. It is based on some experiments about statistic data of delays for control over Internet. Simulation results for several pendulums are presented. Experiments "in hardware" results are also presented (hardware- pendulums, constructed with Lego Mindstorms NXT, software-cloud mechatronic laboratory, http://cmlaboratory.com).
