There are three different aspects of the military robotic that should be differentiated. Starting from the top level there is the Mission Planning, the path planning and the navigation. Mission planning is mission specific and considerably changes according to the scenario.
Firstly with the data provided by the Mission Planning, the Path Planning produces paths and waypoints taking into account the dynamic and kinematics capabilities of the robots involved in the mission. The Navigation consists in avoiding those obstacles while following the paths of initial. In order to pass or avoid obstacles and to recover from small path changes the robots must be equipped with position and distance sensors. Control architectures for navigation are deliberative generally, meaning that there is a strong coupling between the sensors data and the motion commands sent to the robot actuators. These architectures are based on simple behaviors that are combined sing BCM (Behavior Coordination Mechanism). The systems have to be at least provided the following capabilities: sensor information distribution and distributed behavior communication and coordination mechanisms in order to implement coordination.
Several navigation aspects were found vital for military purposes but not yet foreseen to be solved under the current development speed when analyzing the five selected military tasks. Following are vital gaps were found in the field of navigation and mission planning:
• Following of the autonomous road.
• Autonomous driving in mixed traffic.
• Moving in all terrains in all weather conditions.
• Following the leader, manned or autonomous.
To achieve the roadmap, following has to be done:
• Prioritize different driving conditions, concept and agree on real target scenario.
• Decide and develop experimental systems.
• Organize the trials.
• Define the performance measurements.
• Improve the navigation technology through experimental systems.
• Manage the technology group of navigation.
• Develop coordination and interaction within technology group.
