In this direction, a first contribution of this work is an extension of rigidity theory to weighted frameworks and the rigidity eigenvalue, which when positive ensures the infinitesimal rigidity of the framework. We then propose a distributed algorithm for estimating a common relative position reference frame amongst a team of robots with only range measurements in addition to one agent endowed with the capability of measuring the bearing to two other agents. This first estimation step is embedded into a subsequent distributed algorithm for estimating the rigidity eigenvalue associated with the weighted framework. The estimate of the rigidity eigenvalue is finally used to generate a local control action for each agent that both maintains the rigidity property and enforces additional constraints such as collision avoidance and sensing/communication range limits and occlusions. As an additional feature of our approach, the communication and sensing links among the robots are also left free to change over time while preserving rigidity of the whole framework. The proposed scheme is then experimentally validated with a robotic testbed consisting of six quadrotor unmanned aerial vehicles operating in a cluttered environment. }, keywords = {Decentralized control, distributed algorithm, distributed estimation, graph rigidity, multi-robot}, doi = {10.1177/0278364914546173}, url = {http://ijr.sagepub.com/content/34/1/105}, author = {Daniel Zelazo and Antonio Franchi and Heinrich H.

Generally, the dynamics of the body manipulated with uncoordinated forces of thrusters is nonlinear. The problem we consider is how to design the unilateral force each agent applies to ensure the decoupling and linearity of the linear and angular (i.e., translational and rotational) accelerations of the body and thus allow a controller to be designed in a simpler manner, instead of developing sophisticated nonlinear control techniques. Here consider two types of unilateral thrusters with (i) all fixed directions, and (ii) all non-fixed directions, respectively. To address the problem, we design two decomposition frameworks, each with its advantages, on the structure of the forces and control policy such that (i) the linear and angular accelerations of the body are decoupled and controlled independently, and (ii) the control that ensures the forces to be unilateral (only for thrusters with non-fixed directions) is independent from the linear and angular accelerations. As a result, the closed-loop dynamics of the body is linear with respect to both the linear and angular accelerations; thus the control of the body becomes trivial, which may provide a convenient and alternative methodology for design of a physical system with a quick estimation and reference of the manipulated forces required.}, issn = {1573-269X}, doi = {10.1007/s11071-014-1643-3}, url = {http://dx.doi.org/10.1007/s11071-014-1643-3}, author = {Li, Wei and Spong, Mark W.} } @conference {160, title = {Dynamic Movement Primitives for Cooperative Manipulation and Synchronized Motions}, booktitle = {IEEE International Conference on Robotics and Automation (ICRA)}, year = {2014}, author = {J.
