WIRELESS COMMUNICATIONS IN NETWORKED ROBOTICS

IEEE 2009

Summary:

Networked Robots refers to multiple robots operating together incoordination or cooperatively1 with sensors, embedded computers, andhuman users. Cooperation entails more than one entity working toward acommon goal while coordination implies a relationship between entities thatensures efficiency or harmony. Communication between entities isfundamental to both cooperation and coordination and hence the central roleof the network. Embedded computers and sensors are now ubiquitous inhomes and factories, and increasingly wireless ad-hoc networks or plug-and-

play wired networks are becoming commonplace. Robots are functioning inenvironments while performing tasks that require them to coordinate withother robots, cooperate with humans, and act on information derived frommultiple sensors. In many cases, these human users, robots and sensors arenot collocated, and the coordination and communication happens through anetwork.

Abstract:

The XBee/XBee-PRO ZB OEM RF Modules

are designed to operate within the ZigBeeprotocol and support the unique needs of

low-cost, low-power wireless sensornetworks. The modules require minimalpower and provide reliable delivery of data

between remote devices. The modules

operate within the ISM 2.4 GHz frequency

band. The robots are connected in such a waythat the communication between them will be

in a bonded link that they are always

transferring the data so avoid the obstructionand transfer the accurate data from the place

it stays. A robot is equipped with a wireless

camera to transfer the video data of thelocation where the robot goes. That is linked

with the second robot to detect the presence

of metal, heat and presence of humidity from

the locations. The data that is collected by thesecond robot is sent to the first one and this

alerts the user from the location there. This is

done to make a systematic manner to

incorporate the network between to Zigbee

modules in an efficient manner for a lowpower consumption and pinpoint connection

for fast data transfer. The network type usedhere will be a pinpoint type of network forcommunication since we have two modules

to communicate. The rugged nature for the

robots are in such a way that they can travel

in different places. The sense the metal with aproximity sensor that sensory signal finds the

strength of the material and the send the same

to the master other robot to find the locationof that place. If the presence of heat around

that are it detects that and send that to the

robot and gives a continuous image transferto the system. This heat is detected with

thermistor and then the signal is converted in

to digital signal and that is read by the

controller and the same is transfer to theother robot. This forms a link to the both the

robots for continuous transfer of the data

between the robots to from a Zigbee network.
