We study the problem of seeking the source of a scalar signal with a force-and torque-
controlled unicycle. The vehicle does not have the capability to measure or track its position …

We study the problem of source seeking without position measurements in three-
dimensional Euclidean space. The source-seeking agent is modeled by a second-order …

In this letter, an extremum seeking controller (ESC) is designed for stabilization and output
minimization for a class of second-order control-affine nonlinear systems. The main difficulty …

In this paper, we investigate the stabilizing effect of an extremum seeking control law on a
class of underactuated Lagrangian control systems with symmetry. Our study is motivated by …

A Dubins-car like robot travels within an area in which an unknown scalar field exists. Only
sensors that measure the field value at the current location are available. We present a …

This paper presents a simple control approach for global trajectory tracking and formation
control of underactuated surface vessels equipped with only two propellers. The control …

The paper deals with the problem of cooperatively finding a source of an unknown
environmental field by a relatively small group of robots whose communication range is …

A robot of the Dubins-car type travels in a planar workspace that hosts an unknown scalar
field. Two sensors supply the robot with the point-wise field measurements. The paper …
