Get MAD

• Get Me A Drink!!!

6
What is Get MAD

• Get MAD is a prototype vending machine robot that
  operates on Radio Frequency Identification (RFID)
  commands.

7
Basic Operation

• Receives RFID signal from a unique RFID card
  which contains information about the drink to
  vend.
• Navigates to the correct vending tower.
• Triggers the vend switch.
• Receives the drink.
• Returns back to deliver drink.

8
Sensors

• Sonar
• Bump Switches
• Infrared (IR) Sensors
• Radio Frequency Identification (RFID)

9
Sonar

• Obstacle Avoidance
• A sonar sensor is placed on the front for
  Obstacle Avoidance.

10
Bump Switches

• Trigger vending
• A switch is located at the base of every vending
  tower.
• When triggered, it starts the vending process

11
Bump Switches

• Weight Sensor
• The drink holder is situated on top of another
  bump switch.
• Once the drink is delivered into the holder, the
  switch is triggered and the robot begins its
  return to base.

12
Infrared (IR) Sensor

• Line Tracking
• Three infrared sensors are placed at the bottom
  of the robot for line tracking.
• Each one of them must be on top of the line for
  the robot to be on course.

13
Infrared (IR) Sensor

• Intersection and Destination Detection
• A fourth IR sensor will be used as an eye for
  detecting an intersection.
• This sensor will also be responsible for
  detecting the stop point for vending.

14
Special Sensor

• Radio Frequency Identification (RFID)

16
RFID Sensor

• Drink Selection
• An RFID card will inform the robot of what drink
  to vend.

17
RFID Sensor

• Tower Sensing
• Every tower is equipped with an RFID card that
  complements the Drink Selection RFID card.
• If the RFID matches, the robot recognizes what
  tower to vend from.

IR Code Summary

• 3 IR eyes
• Each returns a value of 0 if over white surface
  and 1 if over black.
• 111 equals on course
• 000 equals completely off course
• Remembers previous code in order to bring robot
  back on track from a 000 reading

24
RFID Current

• 2 tags on hand
• One tag 0 the other 1
• Possible combinations go from 00-11
• User black dots to calculate tower position

25
RFID Future

• Multiple tags
• A tag mounted on each tower as ID
• A free tag for each tower for selection
