endeavor. The Word ELECTRONICS was defined by the Institution of Radio Engineers as follows : The Field of Science & Engineering which deals with Electronic Devices & their utilization. The Atmel AT89 series is an Intel 8051-compatible family of 8 bit microcontrollers (µCs) manufactured by the Atmel Corporation. Based on the Intel 8051 core‚ the AT89 series remains very popular as general purpose microcontrollers‚ due to their industry standard instruction set‚ and low unit cost. This allows

TFRH robot is based on embedded system. The TFRH has mainly two Atmel AT89S52 microcontrollers which communicate with each other via an RF module 434 Mhz. This will be explained in the forthcoming sections. The TFRH is based on 8-bit microcontroller The IC used was Atmel AT89S52 ICS. The hardware cost is reduced by removing various sub ICs used in the design. The design part had successfully removed the 8255 IC and had used multiplexer cd 4051 to support the 7 different motor for the various function

the Atmel AVR family of microcontrollers. The program is a native 32bit application that runs under the Windows 95‚ 98‚ NT 4‚ 2000 and XP operating systems. The C cross-compiler implements nearly all the elements of the ANSI C language‚ as allowed by the AVR architecture‚ with some features added to take advantage of specificity of the AVR architecture and the embedded system needs. The compiled COFF object files can be C source level debugged‚ with variable watching‚ using the Atmel AVR
