2. It contains different modules
Object detection and angle determination in
the path using IR sensor.
SMS protocol (F-Bus) development.
Design of RF circuits for data transfer.
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)
