The ability to accurately estimate the position of robotic agents relative to one another, in
possibly GPS-denied environments, is crucial to execute collaborative tasks. Inter-agent …

Ultra wide band (UWB) radio positioning technology is widely used in indoor high-precision
positioning scenes, while obstacles in the wireless signal propagation path will cause the …

The relative pose estimation is one of the most fundamental components for multi-robot
systems, while it still remains an open and challenging research topic in infrastructure-free …

In this article, we study the problem of estimating the four-degree-of-freedom (3-D position
and heading) robot-to-robot relative frame transformation using onboard odometry and …

Inter-agent relative localization is critical for any multi-robot system operating in the absence
of external positioning infrastructure or prior environmental knowledge. We propose a novel …

The vision-based relative localization can provide effective feedback for the cooperation of
aerial swarm and has been widely investigated in previous works. However, the limited field …

In multi-robot missions, relative position and attitude information between robots is valuable
for a variety of tasks such as mapping, planning, and formation control. In this paper, the …

Most distributed algorithms for robot coordination require relative location information, but
how to obtain relative locations in a distributed manner is still a primary problem to address …

The relative position and orientation estimation is one of the most fundamental components
for multi-robot systems, while it still remains an open and challenging research topic in …

Ultra-wideband (UWB) systems are becoming increasingly popular as a means of inter-robot
ranging and communication. A major constraint associated with UWB is that only one pair of …
