  1. Examples of practical applications of BASIC Stamp controller

  2. Some applications of the BASIC Stamp controller • …. • Chalmers University of Technology, Sweden - lab robot camera- you can see whats happening in their laboratory over the web. http://mac5.pe.chalmers.se • Hugh MacMillan Rehabilitation Centre, Toronto, Ontario, Canada, has a project using the STAMP to control an artificial hand for young amputees

  3. Stamp Interfacing • A Robotic bug built by Greg Birdsall and Fred Richards for the X-files uses a BASIC Stamp controller

  4. The Pocket-Bot Robot platform • This miniature robotic vehicle has independent four wheel drive and bumper sensors. • Kits are also available for sensing heat or light and for following a line. http://www.divent.com/pocketbot.html

  6. Stamp Interfacing Example of Stamp Interfacing • Corky'z Robotz- an IR Controlled robotic toy. http://www.geocities.com/ SiliconValley/Park/1302/robotz.htm • Corky'z Robotz- an IR Controlled robotic toy. http://www.geocities.com/ SiliconValley/Park/1302/robotz.htm

  7. Stamp Interfacing Example of Stamp Interfacing A Digital Weather Station using wind direction, wind speed, temperature, humidity and rain gauge sensors. http://oeonline.com/~tparnell

  8. Emminence Airship Project Purpose of this Project: • A fun and exciting learning opportunity Practical Applications • Advertising • Scientific Research • Military and Police • Telecommunications

  9. Physical Design of the Airship • One or more spherical balloons • A plastic gondola to house the electrical equipment • Helium used to fill the balloons

  10. How it Works • User gives commands through a PC keyboard • These commands are relayed through the RF transceivers to the blimp • The blimps on-board intelligence interprets the commands and performs the corresponding functions

  11. The Ground to Air Transmission • The Basic Stamp II gives the transmitter the appropriate bit pattern • The On-Board Stamp then receives the bit pattern from the receiver • Based on the bit pattern received, the Stamp will set the appropriate bits high or low

  12. The On-Board Stamp is interfaced with the motor driver circuit • Propeller motors are used • There is an enable and a fwd/bwd signal for each motor The Motors

  13. Onboard System • Subsystems controlled by CPU GPS Video Compass Motion Control Processor Motion Control Circuitry Central Processor

  14. Internet Based Operations • Operator connects to operation station to assume control PC PC Operation Station PC PC

  15. Reusable Software Design • Robot software specification defined according to system capabilities. • Operator software uses robot specification to coordinate data channels. • Central Mission Control Stations allow for control of robots around the world.

  16. DataTurbine Developer API • Data sources are coordinated and mapped to operator

  17. Robot Software Architecture • Built on Windows OS • Developers API for data transmission with TCP/IP • Interface for operator received controls • Autonomous mission platform Autonomy Application Coordination Application Data Turbine Operating System

  18. OperatorSoftware Architecture • Built on Windows OS • Developers API for data transmission with TCP/IP • Operator communication and control specification • Interface for control devices • Interface for data output Input App Output App Client Core Specification DataTurbine Operatirng System

  19. Future Features • Internet control capabilities • A possible GUI • A joystick or some other device • GPS on-board the blimp • A digital compass on-board • The ability for positional commands • An on-board camera • A possible collaboration with RoverWerx

  20. Future Missions • Autonomous missions with other Intelligent Robots

  21. MIDI communication Protocols

  22. Reminder • Serial Communication (RS-232) • principles • Configuration • Transmission • Programming • MIDI • Characteristics • Transmission • Definitions • Standards • Programming

  23. Serial Comunicacation • Bit by bit • Asynchronous • Serial Protocol for RS-232 (RS-432, MIDI...) • (0 logic [+3,+25V] and 1 logic [-3,-25V]) RS 232C • 110 to 256.000 bauds • Connector with 9 pins, 3 used. • Transmit Data (TXD) pin 3 in DB9 • Receive Data (RXD) pin 2 in DB9 • Ground (SG) pin 5 in DB9 • cables that switch 2 and 3

  24. RS-232 transmission • UART (Universal Asynchronous Receiver/Transmitter) • Parity bits, etc, check it in your documentation. RS-232 Programming COM Ports • In PC • COM 1 3F8 • COM 2 2F8 • COM 3 3E8 • COM 4 2E8

  25. MIDI • Musical Instruments Digital Interface • http://www.midi.org • http://www.harmony-central.com/MIDI/Doc/doc.html

  26. MIDI Transmission • Serial and asynchronous • 31.250 bauds • 1 bit stop and no parity  1 byte = 10 bits • Conector DIN (5 pines, 3 used) and unidirectional cables • Bidirectional communication needs to cables  • (MIDI IN y MIDI OUT)

  27. Examples of connections

  29. Buchla’s The thunder • BioMuse (Brainwave detector!)

  30. Will be in next projects related to Cyber Theatre Many applications of DSP, speech technologies, sound technologies and microcontroller technologies

  31. Micromouse Hardware

  32. Pre-Built Robots Approx. $100 - $200 Contains chassis, motors, wheels and microcontroller (Basic Stamp)

  33. Lego Robotics Kits Easy to prototype Must make your own IR sensors Programming Languages: Logo Not Quite C

  34. Custom Made Mouse Can choose the individual components Can achieve better performance over kits Much more satisfying and fun • Main components: • Microcontroller board • Wall sensors • Motors • Batteries

  35. Propulsion choices DC Motors Servos Stepper Motors • DC Motors • Cheap, small • Need gearbox • Need shaft encoders • H-Bridge • Discrete • SGS Thompson L293D • Can drive two motors • 600mA per motor

  36. Propulsion Servos Need to modify for continuous rotation Need shaft encoders Can be driven without H-Bridge Come with attachments Perfect for Basic Stamp • Stepper Motors • Less torque than DC motors for a given size and weight • Do not need shaft encoders • LSI chips can handle logic and power • Allegro UCN5804LB • 1.25 A • 35 V

  37. Sensors IR Sensors Proximity Easiest to implement Distance Sharp GP2D02 • IR Sensors • Wall Feelers • Wall Feelers • Simple to make and adjust • Tend to get hung up at wall openings

  38. Simple Microcontroller Techniques for Sculpture

  39. Why use microcontrollers in Sculptures? • To sense and respond to viewer’s actions • To sense and respond to environmental changes • To sequence events • To set up contingencies • To control motion, light, sound

  42. Problems to solve • reverse directions of two motors at particular points in their travel • ensure that the moving arms don’t become and remain synchronized

  43. PIC is used to: • check when the motors have hit their CW and CCW limit switches • reverse the motors’ direction • add a little delay to the time it takes one of the motors to reverse directions in order to prevent synchronization

  44. #include <12c509.h> #use delay(clock=4000000) void main () {set_tris_b(0b001111); //four lines are inputs, two are outputs while (1) { if(input(pin_B0)==0) // if cwLampLimit is touched {output_high(pin_B4);} // activate lampMotorRelay} if(input(pin_B1)==0) // if ccwLampLimit is touched {output_low(pin_B4);} // de-activate lampMotorRelay} if(input(pin_B2)==0) // if cwShieldLimit is touched {output_high(pin_B5); // activate shieldMotorRelay delay_ms(500); } //wait half a second to ensure //non-synchronous movement if(input(pin_B3)==0) // if ccwShieldLimit is touched {output_low(pin_B5);} // de-activate shieldMotorRelay} }}
