NASA mission concepts for the upcoming decades of this century include exploration of sites such as steep cliff faces on Mars, as well as infrastructure deployment for a sustained robotic/manned presence on planetary and/or the lunar surface. Single robotic platforms, such as the Sojourner rover successfully flown in 1997 and the Mars Exploration Rovers (MER) which landed on Mars in January of ...

The control system for a personal aid for mobility and health monitoring (PAMM) for the elderly is presented. PAMM is intended to assist the elderly living independently or in senior assisted living facilities. It provides physical support and guidance, as well as monitoring basic vital signs for users that may have both limited physical and cognitive capabilities. This paper presents the desig...

This article presents a network-controlled approach of user terminal mobility within an m based Wireless LANAccess Network. bz a first part, this article makes a review of the mobility support, on the subject of emerging W~N technologies as HIPEICLaN/2 and IEEE 802.11, on the one hand, and, regarding m networks as currently studied within tETF, on the other hand. Both types of lP mobility proto...

Over the past few years, modern mobile subscriber devices such as Smartphones, tablets and PDAs have become more and more popular which use network resources in a more aggressive way and last for longer durations involving dramatically increasing traffic volumes. But traditional mobility management schemes have hardly taken this issue into account. Distributed mobility management is considered ...

The w-iLab.t is a large-scale generic wireless experimentation facility. Two locations are equipped with in total over 260 wireless nodes. In the w-iLab.t Zwijnaarde location mobile nodes are hosted. The mobile nodes are mounted on top of robots, of which the movement can be fully controlled by the experimenter. Due to a high accuracy positioning algorithm, the exact position of the robots is k...

This paper introduces a general policy-based management framework within an IP network. It describes how a policy-based approach can be applied to deal with QoS, security, access control, mobility, etc. The framework presented here is derived from IETF works in Policy Framework working group and in Resource Allocation Protocol working group. Then, we describe some applications that could be han...

In this paper we propose a new engine management system for hybrid vehicles to enable energy providers and car manufacturers to provide new services. Energy forecasts are used to collaboratively orchestrate the behaviour of engine management systems of a fleet of PHEV’s to absorb oncoming energy in an smart manner. Cooperative algorithms are suggested to manage the energy absorption in an optim...

Collection of user statistics and network traffic is crucial for understanding user behavior and for creating network workload models. It is also valuable for the management of commercial wireless networks. In this paper, we report on the analysis of billing records collected from the Telus Mobility Cellular Digital Packet Data (CDPD) network. The longest continuous billing record that we exami...

Many people who are mobility impaired are, for a variety of reasons, incapable of using an ordinary wheelchair. In some instances, a power wheelchair also cannot be used, usually because of the difficulty the person has in controlling it (often due to additional disabilities). This paper describes two low-cost robotic wheelchair prototypes that assist the operator of the chair in avoiding obsta...

Header The control of a legged robot walking on difficult terrain demands the development of efficient and reliable algorithms to coordinate the movement of multiple legs according to a diversity of requirements. We present a control structure, implemented on a six-legged robot, in which the aspects of stability, mobility, ground accommodation, gait generation, and robot heading are integrated ...
