hi sir , i am chandra mouli i want coding,ppts and documentation it will help for completing my project succesfully[/font] to my mail chanduramu1[at]gmail.com and chanduramu5[at]gmail.com
Based on the ARM7 development board, this paper presents the avoiding obstacle and the ZigBee wireless control functions for the omni directional mobile robot. By using ultrasonic transducers, the built-in controller receives the obstacle distance signals, and then calculates the control signals to power three omnidirectional DC motors that are installed in a mobile robot. On the other hand, via the built-in RS-232 port, the controller as well as receives remote control PC signals through the Zig Bee wireless communication. The graphical interface of the human machine is programmed by the Visual Basic software in the PC part; Such mobile robot remote control functions and message transmission are shown on the screen. The results of the experiment provide the ARM7 implementation techniques for the omnidirectional control robot; Also expand ZigBee wireless communication techniques in the field of intelligent robot research.
Mobile robots perform various forms of tasks to serve human beings, such as home robot, robot inspection, robot security, robot education school, robot rehab, and so on. Conventional mobile robots have used the front steering and the rear wheel drive mechanism to respond to all necessary robot movements, but movement restriction is a major problem in using such a mechanism. The omnidirectional configuration is the most suggested mechanism for the mobile robot, which has the ability to change direction within the limited space in the interior environment. To achieve real-time control and provide high-speed with an acceptable error in the omnidirectional directional robot (ODMR-based controller (ARM7) has been widely used by the robotics community.Otherwise, wireless home network technology can be class in wireless LAN, Bluetooth and ZigBee. The ZigBee has advantages such as low power consumption, large transmission range, and the ability of mesh networks, which are more suitable for network sensor applications than other wireless alternatives. Based on the above points, this paper presents an integration of ODMR obstacle control function and ZigBee control function, which are implemented in an ARM 7 development board. A case study of three active omnidirectional wheels was configured to Make the mobile robot the whole move. Also, when combining the ZigBee technique with Visual Basic (VB) program language A human machine graphic interface was used to remotely control the ODMR movement to achieve the desired location.
