Elements of Robotics

1. An Elements of Robotics.
2009

2. Systematic Approach
 Understanding the requirements.
 Rough outline of design.
 Knowledge of components as required.
 Simulation and debugging.
 Physical realization.

3. SENSING CONTROLLING ACTUATING
-Test -Manipulate -Execute
• Sensor • Controller • LCD
• Transducer • Processor • Motor

5. PIC
 ’Peripheral Interface Controller’ by
Microchip.
 Programming software-MPLAB by
Microchip
AVR
 ‘Advanced Virtual RISC’ by Atmel.
 Programming software-AVR studio by
Atmel

6.  AT89Cxx series by Atmel.
 P80C51 or P87V51 by Philips.
 ATmega8 or ATmega16 by Atmel.
 PIC18Fxxxx by Microchip.
 MSP430xxxx by Texas Instruments.

7.  Microcontrollers are self sustainable CPUs
with adequate RAM and ROM.
 uCs are capable of handling devices up to a
certain complexity.
 But are capable of supporting almost all of
our robotics projects.

8. Controllers Peripherals, Drivers , Interfaces
Digital Signal Processors Video and Sound Cards, DAQs
Processors CPUs

10. Piezo-Electric Thermo-Electric
Sound
Ex:Ultrasonic
Temperature
Ex:Thermistor
Pressure
Ex:Pressure Gauge

11. Opto-Electric Chemo-Electric
Light Intensity
and Clarity Chemicals
Ex: LDR, Ex: Gas and
Photo-Diode, Smoke Sensors
Photo-transistor

12.  Motive – “SMART”
 Intelligent use of
mechanical
phenomenon for
sensing.
 Modern Fabrication
processes.
 Applications.

13. PRESSURE - ELECTRICITY
 Converts Pressure into
voltage.
 Converts Voltage into
Pressure.
 Converts Alternating
voltage into Vibrations.
 Converts Vibrations to
Alternating voltage.

14.  A Circuit Biasing the Sensor.
 A Circuit Coupling the sensor to Controller.
Ex: An IR LED Sensor Circuit.

16. STEPPER MOTORS HELICAL MOTORS
 Precision Control  Medium Control
 Slow speed  Comparatively Fast
 Adequate Torque  High Torque

18.  Multi-meter.
 Breadboard.
 Power supply DC 5V and/or 12V.
 Soldering Iron with Stand.
 Soldering wire and De-soldering wire.
 Single Strand & Multi-strand wires.
 Switches and Connectors.
 Devices(LED, R, L, C, Pot., etc).
