“…(Zhou and Roumeliotis, 2006) used a combination of direct and indirect detection approaches, where colored cylinders were installed to be detected by omnidirectional cameras. In addition, (Gentner et al, 2018;Boroson et al, 2020;Cao and Beltrame, 2021) propose to replace visual loop closures by Ultra-Wide Band (UWB) measurements from beacons onboard the robots. Given a few distance measurements provided by the UWB sensors, the robots can estimate their current relative pose with respect to each other and establish a common reference frame.…”

“…An interesting, yet still underdeveloped, trend is to leverage the communication medium for inter-robot measurements. This has been successfully done with UWB (Gentner et al, 2018;Boroson et al, 2020;Cao and Beltrame, 2021) or WiFi (Liu et al, 2020), and could be a promising avenue using multipath analysis with channel estimators in 5G networks (Ge et al, 2021). Future techniques might even sidestep inter-robot data transfer completely by communicating via sensor observations of each other and predetermined cues such as visual tags or behavioral patterns (Kim et al, 2010).…”

“…Significant attention has also been given to UWB as a sensing modality for robotic platforms. TrackIO (Dhekne et al, 2019) deploys a UAV-UWB system to estimate first responders' location and velocity even in deep indoor environments, while the autonomous Puffer project (Boroson et al, 2020) uses UWB for pose graph optimization. However, UWB typically needs to operate on wide bandwidths resulting in significant FCC restrictions on operating range and power (Mahfouz et al, 2009).…”
