Introduction to Mobile Robots
Mobile robotics is an area of active research with enormous,untapped potential for the future – for household use, foruntapped potential for the future for household use, forapplications in industry and production, for elderly care, in hospitalsas well as in a host of other fields.
One of the biggest hurdles is the fact that currently there are nowireless communication technologies available that totally fit theg yspecific needs of robot systems.
However, both for system pricing and for time needed forproducing first standards, it would be highly desirable top g , g yre-use already existing building blocks, both in terms ofprotocols and standards, but also in terms of systemreference architectures, hardware blocks and software

Communication solutions for wireless roboticswireless robotics
At the moment, it is necessary to standardize three basic types of communicationin the field of robotics:
Communication between the individual components of the
robot itself. The internal wiring of robots can become very clumsy, even messy and can become very clumsy, even messy and
unmanageable. Body-area network solutions could become a basis for standardization providing the communication parameter
requirements needed for this applicationapplication.
Communication between a (mobile) robot and a fixed wireless
Communication between robots, without a base station.
Robots should be able to communicate directly with one or a (potentially large) number of
peers, when they get into each other
a (mobile) robot and a fixed wireless base-station. Wireless links based on
currently available technology, i.e. IEEE 802.X, are in routine use for simple tasks.
However, the results in terms of transmission quality latency and in

jointly.
transmission quality, latency and in particular, robustness, are not
completely satisfactory.
Communication parameters for wireless roboticswireless robotics
Depending on the application and the communication solution, therequirements for the network links will vary considerably.However it will be possible to identify limits for minimum serviceHowever, it will be possible to identify limits for minimum servicequality including:
• Bandwidth• Latency Times• Acceptable Compression Losses• Acceptable Compression Losses• Parameters relevant to overall network safety• Minimum end-to-end reliability/availabilityy/ y

Taking a closer look from the networking perspectivenetworking perspective
Evolving toward teams of robotssupported by wireless ad-hoc networks,the main motivation for connecting therobots is to achieve a common mission ofthe robots in a distributed and parallelmanner.manner.
Effective communication among robots isa difficult issue in the coordination ofa difficult issue in the coordination ofgroup behaviour. Real-time wirelesscommunication can help dynamic resourcemanagement and self-organization for ateam of cooperative robots.
Machine to machine communications willquickly become as important as machine-q y pto-human, human-to-machine or human-to-human information exchange. With thisparadigm shift, the average distancebetween communication pairs willcontinuously decrease

Super-intelligent Wireless Personal Cooperative Robot (SPR)
The answers to the challenges lay in smart, intelligent and self-g y , gorganized wireless communications designs: Super-intelligentWireless Personal Cooperative Robot (SPR).
The key concept for implementing SPR is the Wireless CooperativeRobots Network, making use of whatever consumer/controlelectronics devices available in a home/indoor scenario to buildintelligent self-organizing networks.
