Task acknowledgment

20th Oct 2012The first group meeting served to take a deeper reading of the problem, look into similar projects and start creating the conceptual scheme of the questions involved. 
From this meeting we revolved around the following themes



  • Robot Construction guidelines
    • Light sensor protection made with sponge to minimize light changes in the room. We know for a fact that different lighting conditions in the room will dramatically affect the readings of the light sensor.
    • 2 or 3 wheel model of robot? What complexity difference between both? Our minds were set on 2 motorized wheels. We had indications that having a free rotation 3rd wheel would cause problems during rotation. A possible solution could be having only 1 motorized wheel, which would in turn have another motor for steering it. 
    • We must minimize friction for the rotation to be perfect. On the 2 motorized wheel configuration, we had a hint that we could use a round smooth object to serve as 3rd support point. This circumvents the 3rd free rotation wheel problem. The smooth round object will minimize friction.
  • Game doubts
    • When the "Mold" encounters the "Toaster" it loses 1 turn and restarts at position (6,6)? Partially true. It does looses 1 turn but maintains its position and then continues from there on.
    • Smell and temperature are measured how ("Butter" / "Toaster")? Undergoing discussion
    • Positions are indicated at start to the program? No, the Robot has to recognize them as it goes.
    • Or are they determined automatically during the game? Answered before.
    • Is there an initial recognition of the game board? Probably not. We need to discuss this possibility but the spirit of the game indicates that it's probably of the exploring type.
  • Implementation / Logic
    • The route calculation has to consider barrier deviation, the "Toaster", the expectable route of the "Mold" and influence the "Mold" route so that it doesn't hit the "Butter".
