A robot is a good example of a mechatronic system. Most robots integrate software, electronics, and mechanical designs in a synergistic manner (meaning that the separate parts act together in such a way that the combined effect is stronger than the sum of the separate effects of each one of the components). Other examples of mechatronics are the digital thermostat and the anti-lock brake system. Both were originally designed as mechanical systems and have been improved later by their integration with electronic controls and digital computing elements.
