In this paper, we present a numerical algorithm to compute the optimal grasp on a simple polygon, given contact forces of unit total magnitude. Forces are compared with torques over the radius of gyration of the polygon. Our analysis shows that the optimal grasps may be of a continuum. We also address a grasp optimality criterion for resisting an adversary finger located possibly anywhere on the polygon boundary. The disparity between these two grasp optimality criteria are demonstrated by simulation with results advocating that grasps should be measured task-dependently. The paper assumes non-frictional contacts.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

When the lower jaw rapidly closes, it may come in hard contact with the upper jaw if the food is a crushable one. To clarify the mechanism of rapid jaw motion, the authors focused on the nonlinearity of the human muscle that is known in the field of the physiology or biomechanisms. The authors propose a feasible mathematical model for the muscle and its nonlinearity. A nonlinear spring mechanism is then designed based on the mathematical model. As a result of chewing experiment, the authors confirmed control of the rapid closing motion of the robot jaw using the nonlinear spring mechanism.

This paper reports some research results by applying Lenz and Tsai's approach (1989) to calibrate a SCARA arm equipped with a hand-mounted camera. In order to measure robot poses, a new technique was employed to calibrate the camera at various robot configurations. The camera calibration technique is singularity free even when the image plane is nearly-parallel to the camera calibration board. Second, the modified complete and parametrically continuous (MCPC) model was used to describe the geometry of the SCARA arms because there is no model singularity in the MCPC model for this type of robots. Experimental studies were conducted to demonstrate the feasibility of the present approach for calibrating SCARA arms. Some practical recommendations are also made for robot users who need to calibrate SCARA arms.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

The minimal application of inter-robot communication is required to develop an autonomous and flexible mobile robot in such an environment. In order to reduce communication application function of action observation is introduced into a robot. A mobile robot gains more information about the local working environment by observing actions of other robots. It always tries to plan motions for avoiding a collision with its own sensory data. The effectiveness of this approach on collision avoidance is verified with simulation experiments.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

Using an estimated epipolar constraint, the proposed scheme can generate trajectories for the visual servoing system on the 2D image planes by a simple obstacle avoidance method without reconstructing 3D geometry. The proposed scheme is based on the idea, \"as long as one of the projected trajectories does not intersect with projected obstacles, the trajectory in 3D space can avoid the obstacles\". An experimental result is shown to demonstrate the validity of a combination of the proposed trajectory generator and the visual servoing control scheme.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

A sequence of image feature points is used to express the reference trajectory that the mobile object should track and the mobile object is controlled by a feedback control law derived from the sequence of image feature points. This control is robust and flexible because the mobile object tracks a reference trajectory in an object-centered coordinate system of the target object. Moreover, the trajectory can be taught with only an image sequence. Simulation showed that a mobile object can track a trajectory described in an object-centered coordinate system.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

During pushing motion of antenna, the contact point generally shifts on the environment's surface, which either underestimates or overestimates the rotational compliance and eventually brings a sensing error for localizing the contact point. The goal of this paper is to consider the effect of the environment's curvature on the rotational compliance. We show that the rotational compliance of the antenna being in contact with a curved environment depends on not only the contact distance but also on a new nondimensional parameter including the pushing angle and the environment's curvature where the antenna makes contact. We further show experimental results to support the theoretical analysis for various environments with different curvature.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.

With respect to other methods that compute shape and motion from a sequence of images with a calibrated perspective camera, this method converges in a few iterations, is compositionally efficient, and does not suffer from the nonlinear nature of the problem. With respect to factorization and/or affine-invariant methods, this method solves for the sign (reversal) ambiguity in a very simple way and provides much more accurate reconstructions results.","PeriodicalId":124483,"journal":{"name":"Proceedings 1995 IEEE/RSJ International Conference on Intelligent Robots and Systems.
