tinySLAM-based exploration with a swarm of nano-UAVs
Johan Markdahl, Mattias Vikgren
This paper concerns SLAM and exploration for a swarm of nano-UAVs. The laser range finder-based tinySLAM algorithm is used to build maps of the environment. The maps are synchroniz…
Swarm Bug Algorithms for Path Generation in Unknown Environments
Alexander Johansson, Johan Markdahl
In this paper, we consider the problem of a swarm traveling between two points as fast as possible in an unknown environment cluttered with obstacles. Potential applications includ…
Asymptotically stable polarization of multi-agent gradient flows over manifolds
La Mi, Jorge Gonçalves, Johan Markdahl
Multi-agent systems are known to exhibit stable emergent behaviors, including polarization, over or highly symmetric nonlinear spaces. In this article, we eschew lin…
Automatic traction control for articulated off-road vehicles
Johan Markdahl
Construction equipment is designed to maintain good traction, even when operating in difficult off-road conditions. To curb wheel slip, the vehicles are equipped with differential…
Counterexamples in synchronization: pathologies of consensus seeking gradient descent flows on surfaces
Johan Markdahl
Certain consensus seeking multi-agent systems can be formulated as gradient descent flows of a disagreement function. We study how known pathologies of gradient descent flows in Eu…
Robust synchronization of heterogeneous robot swarms on the sphere
Johan Markdahl, Daniele Proverbio, Jorge Goncalves
Synchronization on the sphere is important to certain control applications in swarm robotics. Of recent interest is the Lohe model, which generalizes the Kuramoto model from the ci…
