Figure 1: New time table
Figure 2: Food distributor subfuction
Figure 3: mechanical movement subfunction
Figure 4:food handling & distributing subfunctions
Figure 5: sensor feedback& client request medium subfunctions
Figure 6:track subfunctionSummary:
The best alternative for each subfunction are:
1.mechanical movement subfunction :4 wheel (motor)
2.food handling & distributing subfunctions: tube & tray/slide
3.sensor feedback& client request medium subfunctions : Button (Bulb)
4.track subfunction: single slotted
FAILURE EXPECTATION
1.Sensor
We using IR & LDR sensor. We maybe face with the sensor problem because the data transfer for this sensor as analog signal. That easily gets disturbance and noise from the environment.
2.Track
Because the tyre follows the track, maybe friction will effect to the motion moreover when the tire moving in inline condition. The moving maybe stuck during moving.
3.Motor
We are using cheap motor. We concern about the speed and torque will be affected by the load on the body of robot. That will affect the smooth motion of moving.
4.Interfacing Between Hardware And Software Algorithm.
The software is not compactable with the hardware. Need some modification for interfacing them.
The improvement stage will be done later..
