- 3. "A reprogrammable, multifunctional manipulator designed to move material, parts, tools, or specialized devices through various programmed motions for the performance of a variety of tasks" What is a robot? Role of Robotics in Industrial standards Mostly automatic manipulation of rigid parts with well-know shape in a specially prepared environment. In Medical Mostly semi-automatic manipulation of deformable objects in a naturally created, space limited environment.

- 6. Sensor-Driven Robot Control • To accurately achieve a task in an intelligent environment, a robot has to be able to react dynamically to changes ion its surrounding Robots need sensors to perceive the environment Most robots use a set of different sensors • Different sensors serve different purposes Information from sensors has to be integrated into the control of the robot
- 7. Robot Sensors • Proximity sensors are used to measure the distance or location of objects in the environment. This can then be used to determine the location of the robot. – Infrared sensors determine the distance to an object by measuring the amount of infrared light the object reflects back to the robot – Ultrasonic sensors (sonars) measure the time that an ultrasonic signal takes until it returns to the robot – Laser range finders determine distance by measuring either the time it takes for a laser beam to be reflected back to the robot or by measuring where the laser hits the object
- 8. Robot Sensors • Computer Vision provides robots with the capability to passively observe the environment – Stereo vision systems provide complete location information using triangulation – However, computer vision is very complex • Correspondence problem makes stereo vision even more difficult

- 12. SMS based remote control system BLOCK DIAGRAM Nokia 3310 phone has F-Bus connection that can be used to connect the phone to a microcontroller.
- 13. TRIAC CIRCUIT The device is driven by a triac circuit that acts as solid state relay . The triac circuit is driven by DC voltage input and typically 10 mA of current , which the microcontroller can provide very easily . Thus turning on/off can be accomplished by giving a logic high/low to the input of triac circuit
- 14. Design of RF circuits for data transfer Radio is a device that wirelessly transmit or receive signals in the radio frequency (RF) part of the electromagnetic spectrum to facilitate the transfer of information. The front-end of a radio is comprised of transmitter and receiver. Cellular/mobile radio communications, WLAN, etc., Components involved in designing RF circuits: Low Noise Amplifiers Mixers Clock generators Power Amplifiers Antenna Duplexer Onchip passive components (Inductor, Capacitor and transformer)
