In some complex environment, the train and the base station (BS) cannot connect directly. We compare Pound to the state-of-the-art solutions through extensive experiments and show that it performs equally well, or better in all the test cases, including a control-over-network example. Pound allows the use of multiple ROS masters (roscores), features data compression, and importantly, introduces a priority scheme that allows favoring more important flows over less important ones. In this paper, we present a thorough analysis of the problem and propose a new ROS node called Pound to improve the wireless communication performance by reducing delay and jitter in data exchanges, especially in multi-hop networks. However, the TCP connections that the platform relies on for connecting the so-called ROS nodes presents several issues regarding limited-bandwidth, delays, and jitter, when used in wireless multi-hop networks. With the growth of its popularity, it has started to be used in multi-robot systems as well.

The Robot Operating System (ROS) is a popular and widely used software framework for building robotics systems. We showcase the effectiveness of our approach in an application where two drones have to carry an object from one location to another in a coordinated manner. This information is used in a PID controller with a consensus strategy to perform a coordinated flight defined by a set of waypoints. Thus, each drone knows its current drone's position as much as the position of its partner. Rather than having a central controller, we have implemented a single individual controller for each drone involved in the coordinated flight. For this technique to be utilised, a single camera is mounted onboard the MAV, and even when a monocular camera is used to perform visual SLAM, if the camera angle w.r.t to the base of the drone and altitude are known, then the scale of the MAV's pose can be estimated. In contrast, in this work, we present an approach for GPS-denied scenarios where localisation is resolved by using a well-known technique in robotics: visual simultaneous localisation and mapping. Although impressive, these demonstrations strongly depend on the use of GPS in order to effectively deploy MAVs in a coordinated fashion. In recent years, we have seen demonstrations performed by giant companies such as Intel, where hundreds of drones perform a coordinated flight in the open sky.
Flight coordination of Micro Air Vehicles (MAVs) has become an essential task in the autonomous fight of swarms of drones.
