This document discusses a sensor-based motion control system for a mobile car robot. It contains modules for object detection and angle determination using IR sensors, developing SMS protocol communication, and designing RF circuits for wireless data transfer. The document provides background on robot definitions, types of robotics, and how sensor feedback is used for robot control. It describes proximity, infrared, ultrasonic, and computer vision sensors that robots use to perceive their environment. The mobile car robot project uses an IR sensor to detect objects and determine the robot's path, SMS communication for remote control, and an RF circuit for wireless data transmission.

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.

 Humanoid Robots
Different types of ROBOTICS

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

9. Ways of connecting of mobile car robot

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)
