The preservation of connectivity in mobile robot networks is critical to the success of existing algorithms designed to achieve various goals. The available connectivity control algorithms mainly work through preservation of existing edges in the network. A link may be deleted if distributed decision making determines that the edge is not a cut-bridge. A controller is presented which allows edges...
This paper provides the design and implementation of an -optimal control of a quadrotor unmanned aerial vehicle (UAV). The quadrotor UAV is an underactuated rigid body with four propellers that generate forces along the rotor axes. These four forces are used to achieve asymptotic tracking of four outputs, namely the position of the center of mass of the UAV and the heading. With perfect knowledge...
Many applications require multiple mobile robots to move with a common velocity and at fixed relative distances. We present a time-invariant, state-feedback control law and a novel vision-based pose reconstruction system that allows one differential drive robot to follow another at a constant relative distance. The control law does not require measurement or estimation of the leader robot velocity...
