Standard Interface Between NC-Machine and Industrial Robot

Sammanfattning: The aim of this thesis is the design and implementation of a standardized interface to communicate a NC machine with an industrial robot. This interface consists of an ‘electronic box’ which includes a powerful board that is perfect for automation projects composed of a microcontroller, serial ports, optocouplers, relays, etc… The main component of this PCB is the microcontroller. The Atmel AT90CAN128 microcontroller is a good choice for this purpose since it is perfectly suited for industrial and automotive applications and it supports CANopen and DeviceNet implementation.   The industrial robot’s communication between the board is performed through CAN bus. In order to communicate the interface with the NC machine it has eight optocouplers that are used as inputs and eight relays are used as outputs. Developments of programs using C language to communicate robots and NC machines have been developed by the software that provides Atmel for 8-bit AVR applications called AVR Studio 4 + WinAVR.
