چکیده

The paper deals with vision-based localization and control of leader-follower formations of unicycle robots. Each robot is equipped with a panoramic camera which only provides the view-angle to the other robots. As an original contribution, the localization problem is analytically studied using a new observability condition valid for general nonlinear systems and based on the Extended Output Jacobian matrix. The state of the leader-follower system, estimated via the extended Kalman filter, is used by an input-state feedback control law to stabilize the formation. Simulations as well as experimental results validate the theoretical results and show the effectiveness of the proposed design.

Leader Follower Formation Control of Ground Vehicles Using Dynamic Pixel Count and Inverse Perspective Mapping

This paper deals with leader-follower formations of non-holonomic mobile robots, introducing a formation control strategy based on pixel counts using a commercial grade electro optics camera. Localization of the leader for motions along line of sight as well as the obliquely inclined directions are considered based on pixel variation of the images by referencing to two arbitrarily designated po...

Optimal adaptive leader-follower consensus of linear multi-agent systems: Known and unknown dynamics

In this paper, the optimal adaptive leader-follower consensus of linear continuous time multi-agent systems is considered. The error dynamics of each player depends on its neighbors’ information. Detailed analysis of online optimal leader-follower consensus under known and unknown dynamics is presented. The introduced reinforcement learning-based algorithms learn online the approximate solution...

Persistent Multi-Robot Formations with Redundancy

A multi-robot formation composed of autonomous agents may need to maintain an overall rigid shape for tasks such as collective transport of an object. To distribute control, we construct leader-follow formations in the plane that are persistent: designated “leader” robots control the movement of the entire formation, while the remaining “follower” robots maintain directed local links sensing da...
