WIRELESS COMMUNICATIONS IN NETWORKED ROBOTICS
[attachment=24948]
Summary:
Networked Robots refers to multiple robots operating together in coordination or cooperatively1 with sensors, embedded computers, and human users. Cooperation entails more than one entity working toward a common goal while coordination implies a relationship between entities that ensures efficiency or harmony. Communication between entities is fundamental to both cooperation and coordination and hence the central role of the network. Embedded computers and sensors are now ubiquitous in homes and factories, and increasingly wireless ad-hoc networks or plug-and-play wired networks are becoming commonplace. Robots are functioning in environments while performing tasks that require them to coordinate with other robots, cooperate with humans, and act on information derived from multiple sensors. In many cases, these human users, robots and sensors are not collocated, and the coordination and communication happens through a network.
Abstract:
The XBee/XBee-PRO ZB OEM RF Modules are designed to operate within the ZigBee protocol and support the unique needs of low-cost, low-power wireless sensor networks. The modules require minimal power 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 way that the communication between them will be in a bonded link that they are always transferring the data so avoid the obstruction and transfer the accurate data from the place it stays. A robot is equipped with a wireless camera to transfer the video data of the location 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 the second 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 low power consumption and pinpoint connection for fast data transfer. The network type used here will be a pinpoint type of network for communication 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 a proximity sensor that sensory signal finds the strength of the material and the send the same to the master other robot to find the location of that place. If the presence of heat around that are it detects that and send that to the robot and gives a continuous image transfer to 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 the other robot. This forms a link to the both the robots for continuous transfer of the data between the robots to from a Zigbee network.
