Distributed Architecture For Mobile Navigation
The Distributed architecture for mobile navigation (DAMN) is a mobile robot architecture developed by Julio K. Rosenblatt at Carnegie Mellon University. DAMN consists of a collection of independently operating behaviors such as "go-to-goal" and "avoid obstacle", and an arbiter. The arbiter generates a set of feasible action possibilities for the robot over a short time horizon, and the behaviours vote on (i.e. express utility for) these candidate actions. Votes may be weighted by a mode manager. The Pareto optimal action is then sent to the vehicle controller. One method of obtaining votes is for behaviours to asynchronously update a utility map over the configuration space of the robot. The arbiter then overlays paths resulting from action candidates onto the map, and samples utilities along the paths. This approach is known as ''utility fusion''. In DAMN, the decision-making process is distributed and asynchronous, without the need for an hierarchical structure. See also * Th ...

Mobile Robot
A mobile robot is an automatic machine that is capable of locomotion.Hu, J.; Bhowmick, P.; Lanzon, A.,Group Coordinated Control of Networked Mobile Robots with Applications to Object Transportation IEEE Transactions on Vehicular Technology, 2021. Mobile robotics is usually considered to be a subfield of robotics and information engineering. Mobile robots have the capability to move around in their environment and are not fixed to one physical location. Mobile robots can be "autonomous" (AMR - autonomous mobile robot) which means they are capable of navigating an uncontrolled environment without the need for physical or electro-mechanical guidance devices.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Transactions on Robotics, 2021. Alternatively, mobile robots can rely on guidance devices that allow them to travel a pre-defined navigation route in relatively controlled space.Hu, J.; Tur ...
