Multi-robot system

Abstract A multi-agent system, comprising a server and at least two robots controllably wirelessly connected with the server, where the server contains at least one software agent allocated to each robot, which software agent provides abstraction from the robot being implemented in the hardware and enables to calculate, analyze, optimize and control the implementation of different scenarios of robots operation. The robots with marker sensors, odometers and collision sensors send their location and a (part of a) global map of a to a server with a global map, robots’ positions and marker positions, the server updates the global map, plans work of the robots in optimal way, divides the environment in areas allocated to the robots.

TRACKED PLATFORM FOR ROBOTIZED VEHICLE PROVIDED WITH MOBILE TRACK SEGMENT

Abstract The invention is related to mechanics, in particular to devices, configurations and methods that provides high mobility and wide use of the tracked platforms int. al. development of mobile robots. The goal is to provide a platform with high mobility and ability to move in rough terrain and ensure a good contact with the terrain. The platform includes central chassis, driving wheels with appropriate track tensioners, tracks – one for each side, pulleys, movable front heavers, heaver springs and additional pulleys that maintain good wheel contact with the track and acts as a track vibration reducer. While platform moves, if an obstacle is relatively far and therefore heaver’s arm is large, track adapts to the obstacle configuration providing better contact with the terrain, but when the heaver’s arm is small enough, the heaver spring lifts up the platform thereby allowing to get over the obstacle effectively. This relatively simple construction reduces platform’s dependence on operator’s direct sight contact or complex sensor systems in order to operate autonomously and maintaining good abilities to overcome obstacles.

Abstract The invention is related to mechanics, in particular to devices, configurations and methods that provides high mobility and wide use of the tracked platforms int. al. development of mobile robots. The goal is to provide a platform with high mobility and ability to move in rough terrain and ensure good contact with the ground. The platform includes central chassis, eight driving wheels that in pairs are coupled with tracks, wheel pair joints, and independent chassis joints that allow to move independently of the left and right side wheel sections. The chassis joints maintain the chassis in balance during motion. This allows to overcome obstacles that maintain different loads on left end right side wheel sections without loss of balance or contact with the ground. Tracks provide relatively high road adherence and uses only one motor for each wheel pair thereby simplifying the construction.
