Part A
State the trends in mechatronics.
Answer
Current trends in mechatronics include the integration of Artificial Intelligence (AI) for predictive maintenance, the expansion of the Internet of Things (IoT) for real-time connectivity, and the development of miniaturized systems like MEMS.
Write about digital i/o devices.
Answer
Digital I/O devices are components that communicate data in binary form (0 or 1). Input devices like push buttons, limit switches, and proximity sensors provide binary signals to a controller, while output devices like LEDs, relays, and solenoid valves receive binary commands to perform physical actions.
