Mechatronics Mechatronics The term mechatronics was ‘invented’ by a Japanese engineer in 1969, as a combination of ‘mecha’ from mechanisms and ‘tronics’ from electronics. The word now has a wider meaning, being used to describe a philosophy in engineering technology in which there is a co-ordinated, and concurrently developed, integration of mechanical engineering with electronics and intelligent computer control in the design and manufacture of products and processes. As a result, mechatronic products have many mechanical functions replaced with electronic ones. -William Bolton Mechanics mecha Mechatronics Eletronics tronics Mechatronics Defined “Integration of electronics, control engineering, and mechanical engineering.” – W.

Mechatronics VS Robotics Robotics can be considered as part of Mechatronics as it involves these mechanical, electronics and computer engineering fields. A robot is a good example of a mechatronic system.

Charles Ume Embedded systems The term embedded system is used where microprocessors are embedded into systems and it is this type of system we are generally concerned with in mechatronics. A microprocessor may be considered as being essentially a collection of logic gates and memory elements that are not wired up as individual components but whose logical functions are implemented by means of software. For a microprocessor to be used in a control system, it needs additional chips to give memory for data storage and for input/output ports to enable it to process signals from and to the outside world. Microcontrollers are microprocessors with these extra facilities all integrated together on a single chip. 03 MICROPROCESSOR VS MICROCONTROLLER Parameters Microprocessor Microcontroller Applications Gaming, web browsing, Dedicated for specific task document creation etc. (camera, washing machine) Structure Memory and I/O device CPU, Memory, and I/O are connected externally present internally Cost and Power High Low consumption Memory (RAM) 512 MB up to 32 GB 2KB up to 256 KB Storage (ROM) Hard Disk (128 GB to 1TB) Flash memory (32 KB to 2MB) Size of Registers, Address 32 bit or 64 bit 8 bit, 16 bit or 32 bit and data bus
