| | PDF (990 KB) | HTML Media

A 5-SPU robot with collinear universal joints is well suited to handle an axisymmetric tool, since it has five controllable degrees of freedom, and the remaining one is a free rotation around the tool. The kinematics of such a robot also having coplanar spherical joints has previously been studied as a rigid subassembly of a Stewart-Gough platform, which has been denoted a line-plane component. He... View full abstract»

| | PDF (882 KB) | HTML

Body movements of flying insects change their effective wing kinematics and, therefore, influence aerodynamic force and torque production. It was found that substantial aerodynamic damping is produced by flapping wings through a passive mechanism termed “flapping countertorque” during fast yaw turns. We expand this study to include the aerodynamic damping that is produced by flapping... View full abstract»

Publication Year: 2011, Page(s):865 - 875

| | PDF (549 KB) | HTML

Variable stiffness actuators are a particular class of actuators that is characterized by the property that the apparent output stiffness can be changed independent of the output position. To achieve this, variable stiffness actuators consist of a number of elastic elements and a number of actuated degrees of freedom, which determine how the elastic elements are perceived at the actuator output.

• ### A Vacuum-Based Bonding Mechanism for Modular Robotics

Publication Year: 2011, Page(s):876 - 890
Cited by:  Papers (9)
| | PDF (1735 KB) | HTML Media

We explore vacuum as bonding force for modular robotics. Vacuubes are a set of modules that propagate vacuum across their interfaces in order to generate adhesive forces to form and hold structures. We use analog circuits to simulate vacuum transients and understand critical design parameters and then validate these insights in experiments. A 49-module structure that employs vacuum bonding is demo... View full abstract»

• ### Analysis of Bounded Cable Tensions in Cable-Actuated Parallel Manipulators

Publication Year: 2011, Page(s):891 - 900
Cited by:  Papers (27)
| | PDF (883 KB) | HTML

Cable-actuated parallel manipulators (CPMs) rely on cables instead of rigid links to manipulate the moving platform in the taskspace. Upper and lower bounds imposed on the cable tensions limit the force capability in CPMs and render certain forces infeasible at the end effector. This paper presents a geometrical analysis of the problems to 1) determine whether a CPM is capable of balancing a given... View full abstract»

• ### A Kinematic Control Framework for Single-Slave Asymmetric Teleoperation Systems

Publication Year: 2011, Page(s):901 - 917
Cited by:  Papers (24)
| | PDF (1606 KB) | HTML Media

This paper is concerned with asymmetrical teleoperation, where the master/slave subsystems have different degrees of mobility. In particular, dual-master trilateral control of a possibly kinematically redundant slave robot (KRSR) and single-master control of a kinematically deficient slave robot (KDSR) are considered. In the case of a KDSR, the motion of the master robot is restricted to the natur... View full abstract»

Cited by:  Papers (84)
| | PDF (1328 KB) | HTML

This paper presents a novel human-like learning controller to interact with unknown environments. Strictly derived from the minimization of instability, motion error, and effort, the controller compensates for the disturbance in the environment in interaction tasks by adapting feedforward force and impedance. In contrast with conventional learning controllers, the new controller can deal with unst... View full abstract»

• ### Flocking for Multiple Elliptical Agents With Limited Communication Ranges

Publication Year: 2011, Page(s):931 - 942
Cited by:  Papers (14)
| | PDF (721 KB) | HTML

In existing flocking and coordination control systems of multiple agents, an agent is considered as a single point or a circular disk. For agents with a long and narrow shape, fitting them to circular disks results in a problem with the large conservative area. This paper presents a design of distributed controllers for flocking of N mobile agents with an elliptical shape and with limited c... View full abstract»

• ### Learning Stable Nonlinear Dynamical Systems With Gaussian Mixture Models

Publication Year: 2011, Page(s):943 - 957
Cited by:  Papers (118)
| | PDF (2410 KB) | HTML

This paper presents a method to learn discrete robot motions from a set of demonstrations. We model a motion as a nonlinear autonomous (i.e., time-invariant) dynamical system (DS) and define sufficient conditions to ensure global asymptotic stability at the target. We propose a learning method, which is called Stable Estimator of Dynamical Systems (SEDS), to learn the parameters of the DS to ensur... View full abstract»

In this paper, we propose a new information theoretic approach to achieve visual servoing directly utilizing the information (as defined by Shannon) contained in the images. A metric derived from information theory, i.e., mutual information, is considered. Mutual information is widely used in multimodal image registration since it is insensitive to changes in the lighting condition and to a wide c... View full abstract»

Percutaneous intervention has attracted significant interest in recent years, but many of today's needles and catheters can only provide limited control of the trajectory between an entry site and soft tissue target. In order to address this fundamental shortcoming in minimally invasive surgery, we describe the first prototype of a bioinspired multipart probe that can steer along planar trajectori...

• ### Solvability-Unconcerned Inverse Kinematics by the Levenberg–Marquardt Method

Publication Year: 2011, Page(s):984 - 991
Cited by:  Papers (30)
| | PDF (1500 KB) | HTML

A robust numerical solution to the inverse kinematics is proposed based on the Levenberg-Marquardt (LM) method, where the squared norm of residual of the original equation with a small bias is used for the damping factor. A rather simple idea remarkably improves the numerical stability and the convergence performance, even in unsolvable cases. Discussion is done through an investigation of the con...

This paper studies a distributed path-planning problem: How can a sensor network help navigate a nontrial robot to its desired goal in a distributed manner? We consider the case where each sensor node is equipped with sophisticated sensors capable of giving a map for its sensing region. We propose a distributed sampling-based planning algorithm, where every sensor node creates a local roadmap in i... View full abstract»

Publication Year: 2011, Page(s):1004 - 1010
Cited by:  Papers (18)
| | PDF (1008 KB) | HTML

This paper proposes a new set-membership approach to solve range-only simultaneous localization and mapping (SLAM) problems in the case where the map is described by an arbitrary occupancy set (i.e., we do not assume that the map is composed of segments, punctual marks, etc.). The principle is to transform the SLAM problem into a hybrid constraint satisfaction problem (CSP), where the variables ca... View full abstract»

A concept of online trajectory generation for robot motion control systems that enables instantaneous reactions to unforeseen sensor events was introduced in a former publication. This concept is now extended with the important feature of homothety. Homothetic trajectories are 1-D straight lines in a multidimensional space and are relevant for all straight-line motion operations in robotics. This ... View full abstract»

A new feedback control model is provided that allows a wheeled vehicle to follow a prescribed path. Differently from all other methods in the literature, the method that is proposed neither requires the computation of a projection of the robot position on the path, nor does it need to consider a moving virtual target to be tracked. Nevertheless, it guarantees asymptotic convergence to a generic 2-... View full abstract»
