First, we develop a kinematic model of the vehicle in error coordinates expressed in a moving reference frame, which is partially linked to the vehicle. We give a change of coordinates and input combined with a new variable instead of the time-index that transform the original system into a form that can be viewed as a perturbation of a nominal linear time-invariant system. The nonlinear term in the perturbed system satisfies a linear growth bound. Subsequently, linear control feedback is applied to the full nonlinear system and local exponential stability of the closed-loop perturbed system is achieved. Simulation results illustrate the effectiveness of the proposed controller.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The most crucial step in the vision-based estimation of the vehicle motion consists on detecting matchings between image pairs. Here we propose the extensive use of texture analysis as a tool to ameliorate the correspondence problem in underwater images. Once a robust set of correspondences has been found, the three-dimensional motion of the vehicle can be computed with respect to the bed of the sea. Finally, motion estimates allow the construction of a map that could aid to the navigation of the robot.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

In this paper, we propose a simple color landmark model for self-localization and a fast landmark detection and tracking algorithm based on the proposed landmark model. We develop a color landmark with symmetric and repetitive structures, which shows invariant color histogram characteristics under some geometric distortions. Detection and tracking of the model are accomplished by a factored sampling technique in which color similarity is estimated by the color histogram intersection. We also use the color similarity to update the color histogram model of the landmark model for robust tracking under illumination change. We demonstrate the feasibility of the proposed technique through experiments in cluttered indoor environments.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

Our work is based on looking at the displacement estimate that can be derived from registering overlapping imagery of the seafloor. Our approach is realistic in that it does not require large overlap and in that it can handle translational and rotational motions between image pairs in an unstructured terrain. We demonstrate our approach on a photographic survey conducted by the Argo towed vehicle covering several square kilometers off of Guam in the Pacific Ocean over a period of almost two months.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

We consider mobile robots equipped with low degree-of-freedom \"palm manipulators.\" The advantage of using this sort of nonprehensile (i.e. nongrasping) manipulator is its simplicity and versatility.

Accordingly, a general solution can be written by solving the nonlinear equations in the correct order. Another implication of this structure is that a completely general solution to the linearized (perturbative) dynamics exists. The associated vector convolution integral is the general relationship between the output error and both the input error and reference trajectory. Solutions for errors in individual coordinates are in the form of line integrals in state space. Response to initial conditions and translational scale errors, among others, is path independent and vanishes on all closed trajectories. Response to other errors is path dependent and can be reduced to expressions in error moments of the reference trajectory. These path dependent errors vanish on closed symmetric paths, among others. These theoretical results and the underlying error expressions have many uses in design, calibration, and evaluation of odometry systems.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.

Tasks are performed using a unique six-degree-of-freedom (6-DOF) magnetic levitation haptic device. The arrangement allows a user to exert and experience real and virtual forces using the same 6-DOF device. During the virtual task, a peg and hole are rendered haptically, and visual feedback is provided through a graphical display. During the real task, a physical peg is attached to the underside of the haptic device. Using only real forces/torques, the peg is inserted into a hole in a plate attached to a force/torque sensor, while positions/orientations are measured by the haptic device. positions/orientations and forces/torques are recorded for both modes. Preliminary results indicate increased task time, larger total forces and more failures occur with the virtual task. Recorded data reveal user strategies that are similar for both tasks. Quantitative analysis of the strategies employed should lead to identification of significant factors in haptic interface design and haptic rendering techniques.","PeriodicalId":319679,"journal":{"name":"Proceedings 2001 IEEE/RSJ International Conference on Intelligent Robots and Systems.
