Abstract

A robotic platform is presented, having a tiltable operational assembly. The operational assembly incorporates imaging means, designation means and operational means in a synchronized manner thus simplifying the maneuvering of the robotic platform and the operation of its operational means by a remote operator. The operational assembly can be tilted backwards in order to shift the center of gravity of the robotic platform towards its rear to decrease pressure from the front end of the robotic platform to the ground. Alternatively, the operational assembly can be used as an arm which applies pressure over obstacles to raise its distal end from the ground while overcoming obstacles. Tilting the operational assembly also provides double-sided operation of the robotic platform without the need to perform maneuvers which flip the entire robotic platform.
