Resumen:

Control of an autonomous robot moving in cluttered environments guided by a single CCD camera is described in this paper. The objective is to guide the mobile robot to arrive at a goal pose (position and orientation) started from an initial pose in the environment where there may be static obstacles that can be observed by the camera. The control scheme consists in three modules: the control module which ensures the exponential tracking to a desired trajectory; the on-line path/trajectory planning module which plans the desired path using LOS (Light-of-Sight) strategy and then parametrizes it into a trajectory; and the depth-estimation module which takes a sequence of target image along the path in the CCD camera mounted in the mobile robot to estimate the target Cartesian coordinate in the inertial frame and passes it to the path/trajectory module. The trajectory tracking controller and the depth observer are devised relying on the contraction analysis ensuring the exponential convergence in both designs. Simulations are included to illustrate the control scheme. © 2019 ACM.
