Functionality List

The functionality of the pre-programmed robot must include sensory detection, ball retrieval system, and wireless communication. Below is a list of the further definitions of each functionality.
(designed /constructed/Integrated /tested

1. Must use phototransistor to detect the grid and follow it(Tested)
      o Has to be somewhat close to detect
      o QRD 1114 x4
      o Air/Black : Max Values
      o White : Low Values
      o Follow the grid through ranges of values in code

2. Must calculate distance traveled (Designed)
     o Through the code

3. Must tilt the ball latch for the ball to drop down and the ball must land in the catcher (Tested)
     o At the Beacon
     o Elastics to hold the ball latch
     o Detect the ball inside the catcher with micro switch

4. Must use IR sensors for the robot to communicate with the two beacons to determine direction to travel in (Tested)
    o Real-time updates
    o Receiver: 751-1023
    o Transmitter:751-1209-ND
    o The receivers and transmitter must be on the same level

5. Must wirelessly communicate with the farmer to give updates to ZigBee series 2 modules (Tested)
   o WRL10414

6. Must be pre-programmed to perform autonomously to complete the four tasks (Tested)
   o Must move by itself using wheels : DU-BRO 3.00 (must have good traction)
   o Have its own power supply : LC18650
   o Commissioning/Programming the Arduino Board (Pro Mini/Mega)
   o One controller for motor loops (Mega), another for sensor loops (Mini)

7. Must have Proximity Sensor detect walls/obstacles (Tested)
   o Avoid them
   o Around 30cm

8. Must map out the arena with beacon location, obstacles, and past movements (Designed)
   o Arduino Code : 2D Array

If the robot performs each of these functions properly, the robot would successfully rescue both sheeps and complete all four allotted tasks.
