Abstract: A multifunctional track system with two or more independently movable trolleys which can run along the track system and are adapted to receive multiple interchangeable components for data collection, navigation, and cargo transportation is disclosed. The trolleys and the track system communicate data to a central station, which monitors and sends instructions to the trolleys. The system can have horizontal, vertical or angular segments and the trolleys are enabled to move along all segments and switch between tracks. Various operational units in the trolleys are possible in the same system.

Abstract: The invention a multi-purpose, multi-reusable, multi-ejectable grenade and anti rioting device in a single unit.
