Bearing-Only Formation Control with Limited Visual Sensing ....

This work solves the bearing-only formation control problem for two agents with limited field-of-view sensing. We propose a bearing-only control strategy for both the position and heading of each agent that guarantees the desired formation is obtained from almost all initial conditions, and ensures that the agents always remain inside the field-of-view of the sensor.

Bearing-based formation control of a group of agents with ....

[9]. In bearing-based formation control problems, a group of autonomous agents (mobile robots, UAVs) has to achieve a target formation specified by some bearing information (bearing vectors and/or subtended bearing angles) [10]. A focus of bearing-based formation control is designing decentralized control laws using only bearing information.

Bearing-Based Formation Control of a Group of Agents With ....

A focus of bearing-based formation control is designing de-centralized control laws using only bearing information. Con-sider a small quadcopter, the relative bearing, which is the unit vector obtained from a relative position vector by normalizing its length, can be acquired from the onboard cameras, thanks to vision-based techniques [6], [11].

Bearing-only formation control using an SE(2) rigidity ....

Each agent is tasked with maintaining predetermined bearings with their neighbors. Using the recently developed rigidity theory for SE(2) frameworks [1], we propose a gradient-type controller to stabilize the formation. The central construct in the SE(2) rigidity theory for this work is the directed bearing rigidity matrix.

Physical Interpretation of Rigidity for Bearing Formations ....

Research on formation control and cooperative localization for multirobot systems has been an active field over the last years. A powerful theoretical framework for addressing formation control and localization, especially when exploiting onboard sensing, is that of formation rigidity (mainly studied for the cases of distance and bearing measurements).
