Ambulation by crutches takes up to twice the energy of normal gait and can lead to injuries of the hands and arms. The compliant composite forearm crutch described in this article seeks to address these problems. The new crutch is made of a single composite piece and has an S-curve in the main body to provide shock absorption and return of energy with the goal of reducing impact and repetitive ...

The objective of the authors is to achieve a vertical jump in experimentation using the humanoid robot HRP-2. After satisfactory results considering rigid foot ground contact, this paper studies the vertical jump considering a compliant contact and discusses the differences between both models.

In a grid computing environment, heterogeneous resources are distributed in multiple VOs which may have different local policies. Hence, scheduling and resource management are challenging tasks in this context. Since a meta-scheduler is able to provide a virtualized resource access interface to end users, and enforce global policies for both resource providers and consumers as well, it plays mo...

The paper presents a formal approach to prototyping of products in virtual reality environments. Virtual prototyping of products is considered as a consistent simulation and visualization process mapping the source product model into its target visual representations. The approach enables to interrelate formally the product and visual information models with each other by defining mapping rules...

Service Availability Forum has defined a set of APIs to enable the building of off-the-shelf components for applications providing highly available services. A set of services has been defined and the Availability Management Framework is the service responsible of managing availability and therefore shifting this task from the applications to the middleware. Designing an AMF compliant configura...

We present a fully scalable cell injection system in a lab on a chip format that allows for on-chip cell pre-processing, injection and post-processing. Injection is performed by an integrated microneedle which is actuated by the compliant deformation of the PDMS (polydimethylsiloxane) fluidic channel by a single axis actuator. The needle actuation is 90.9% of the applied displacement. The cells...

The adhesion and friction behavior of soft materials, including compliant brushes and hairs, depends on the temporal and spatial evolution of the interfaces in contact. For compliant nanofibrous materials, the actual contact area individual fibers make with surfaces depends on the preload applied upon contact. Using in situ microscopy observations of preloaded nanotube hairs, we show how nanotu...

This paper gives an overview of the different levels of sensor processing complexity found in forcecontrolled tasks, and explains which techniques from Bayesian probability theory are appropriate to cope with uncertainties and missing information at each of the different levels. The paper reduces all approaches for “intelligent” compliant motion sensor processing to a basic set of just four cla...

We propose algorithms to synthesise the specifications modelling the capabilities of an agent, the environment she acts in, and the governing norms, into a process graph. This process graph corresponds to a collection of courses of action and represents all the licit alternatives the agent may choose to meet her outcomes. The starting point is a compliant situation, i.e., a situation where an a...

Although the grasp-task interplay in our daily life is unquestionable, very little research has addressed this problem in robotics. In order to fill the gap between the grasp and the task, we adopt the most successful approaches to grasp and task specification, and extend them with additional elements that allow to define a grasp-task link. We propose a global sensor-based framework for the spe...
