Science teaching in secondary schools is often abstract for students. Even if some experiments can be conducted in classrooms, mainly for chemistry or some physics fields, mathematics is not an experimental science. Teachers have to convince students that theorems have practical implications. We present teachers an original and easy-to-use pedagogical tool: a cable-driven robot with a Web-based...

This paper presents a novel approach to remote tactile interaction, wherein a human uses a telerobot to touch a remote environment. The proposed system consists of a BioTac tactile sensor, in charge of registering contact deformations, and a custom cutaneous device, in charge of applying those deformations to the user’s fingertip via a 3-DoF mobile platform. We employ a novel data-driven algori...

Individuals often act out intended actions in situations where they are unnecessary or have no impact on the execution of that intention. We refer to these behaviors as redundant actions. Despite the apparently superfluous nature of redundant actions, they are frequently produced in certain situations and have the potential to provide insight into the embodied nature of intentions. One clear ex...

This paper describes the design, implementation and evaluation of Electronic Blocks, blocks with electronic circuits inside them. By placing Electronic Blocks on top of one another young children build “computer programs” – each stack of Electronic Blocks is capable of a different function. Significantly, the blocks programming input and program output are based in the physical world, with the ...

Teed lines are widely used in rural power networks in China. The paper theoretically analyzes the voltages and currents when a single line-to-ground fault occurs, constructs a new mathematical model for fault location on the teed lines, performs corresponding MATLAB simulations. Simulation results show that currents near the source (bus M) are almost independent of fault positions and fault res...

In this paper we present a telerehabilitation system aiming to help physiotherapists on the shoulder and elbow treatment. Our system is based on a two-arm haptic force feedback to avoid excessive efforts and discomfort with the spinal column and is remotely controlled by smart phone. The validation of our system, with the help of muscular effort measurements (EMG) and supervised by a physiother...

The existence of digital artifacts commonly used to interact with current television system does not guarantee that those devices are adequate to the developments with iDTV, where new types of applications should be offered. The coexistence of an increasing number of facilities that make use of the remote control could result in more complex interfaces limiting its popularization. This article ...

High-capacity wireless IP networks with limited delays are nowadays being deployed in both underground and open-pit mines. This allows for advanced remote control of mining machinery with improved feedback to operators and extensive monitoring of machine status, wear and fatigue. Wireless connectivity varies however depending on channel impairments caused by obstacles, multi-path fading and oth...
