Visual servoing requires an object in the field of view of the camera, in order to control the robot evolution. Otherwise , the virtual link is broken and the control loop cannot continue to be closed. In this paper, a novel approach is presented in order to guarantee that the object remains in the field of view of the camera during the whole robot motion.(More)
Precision agriculture involves very accurate f a r m vehicle control along recorded paths, which are not necessarily straight lines. In this paper, we investigate the possibility of achieving this task with a CP-DGPS as the unique sensor. T h e vehicle heading is derived according t o a Kalman state reconstructor, and a nonlin-ear velocity independent(More)
