Introducttion to robotics and microcontrollers

  1. 1. Name: Raja Sekar.GRoll No: 41
  2. 2.  A general overview of what robots are, and theessential components embedded within Relevant examples of microcontroller and robotapplications to help the participants understandcontexts and applications of these technologies Contextual understanding makes it easier to relateprogramming efforts to basic science, math, orengineering concepts
  3. 3.  A microcontroller is a kind of miniature computerthat found in all kinds of gizmos Generally speaking, if a device has buttons anda digital display, chances are it also has aprogrammable microcontroller brain.
  4. 4. Microcontrollers are single chipcomputers specifically designed to:◦ Read input devices, such as buttons and sensors◦ Process data or information◦ Control output devices, such as lights, displays, motorsand speakers
  5. 5.  The BASIC Stamp 2 embeds a microcontroller, thePIC16C57, on a module to make programming anduse very simple, yet very powerful. Additional components on the module provideeverything needed to systems and applications, likerobotics.
  6. 6. 5V RegulatorRegulates voltageto 5V with a supply of5.5VDC to 15VDCResonatorSets the speed at whichinstructions are processed.EEPROMStores the yourPBASIC program.Interpreter ChipReads the BASICprogram from theEEPROM and executesthe instructions.Serial SignalConditioningConditions voltagesignals between PC serialconnection (+/- 12V) andBASIC Stamp (5V) forProgramming.
  7. 7.  A robot is a machine that gathers information aboutits environment (senses) and uses that information(thinks) to follow instructions to do work (acts)◦ The “sensing” part provides input to the robot throughswitches, light sensors,◦ The thinking part is the microcontroller brain◦ The acting part could be through lights, motors, actuators,sounds, etc
  8. 8.  Robots come in many shapes and sizes1. Kawadas HRP-3P humanoid robot2. Fanuc ArcMate 100i precision, high-speed welding and cutting robot3. MINI-ROBOT RESEARCH —Sandia National Laboratories4. Mini-robot that can travel throughthe bloodstream
  9. 9. EcologicalData CollectionEME SystemsUndersea ResearchHarbor BranchInstituteJP AerospaceTest Launch
  10. 10.  Robotics requires a basic understanding of electricityand simple wiring diagrams The relationship between current, voltage and resistanceis expressed by what is known as Ohm’s Law, variationsof which are expressed below:V = IR; I = V/R; R = V/IRVI+VR+ -
  11. 11.  Simple programming to cause Boe-Bot to performbasic tasks Adding input and output circuits Making sounds Measuring and calculating◦ Distances◦ Angles◦ Speed◦ Rotation
  12. 12.  Acceleration Tilt and tilt angle Incline Rotation Vibration Collision Gravity
  13. 13.  Sensing and measurements Signal Conditioning Data logging Graphical analyses Feedback continuous control
  14. 14.  Parallax Educational Resources◦ http://www.parallax.com/html_pages/edu/index.asp What is a Robot?
