DISCUSSION

Since the last 3 months ago, we have mission to produce a functional autonomous robot for serving water or food during either meeting or convention session for our Mechatronics System Design. For that reason, we have equipped the robot with intelligence system and embedded with flexible function during its operation.

Since we have limited budget and equipments, most of the materials that are used for this project from recycle materials that can be found in MSD lab, Robocon lab and Mechatronics workshop. The design of prototype needs lots of modification compared to the alternatives design that we have chosen before due to the problem that we faced to find the exact materials for this prototype concept. Thus, from that, our finalized budget for this project less than RM 50 because many materials are from recycle things. The final prototype design as shown below.

PROTOTYPE PRODUCT

By the way, due to the load is quite heavy because of a box we put onto the base car, make the motor cannot run very well since the torque is quite small rather than the load. The motor torque and speed cannot bear the force from the heavy load of the box, causes it sometime stuck during running.

However, we have successful created the food container which the foods or beverages will be brought by robot and the customer just push the button to make it throw out the food from the box. The box is created by plank and we design it well in order the food can go out from container easily.

The single slotted track we have created it from aluminium element because of easy to figure it as same as the shape we want to create such as for corner side (round shape). So, the tyres of the robot run and follow very well in the slotted track. It can rotate the table smoothly by following the track depend on suitable speed that mean not much faster or too slow.

CONCLUSION

Our objective of this experiment has been achieved although it doesn’t function well during presentation. Based on our knowledge learned in the Mechatronics degree programme, our ideas to improve the project is always in our mind. This project is an introduction to the world of robot that aids our daily life. Hence, with this robot there is safety for confidential meeting and also it can save companies money from using in unnecessary things.

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 subfunction

Summary:

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..

PROJECT DEVELOPMENT WEEK 5

2009-09-07T21:39:00.000+08:00

Below are some design for our prototype..We have list 7 of them here..

Alternative 1:conveyor

Alternative 2: Arm mechanism

Alternative 3: Rotation tray

Alternative 4:button and ejector

Alternative 5: Tube & tray/slide

Alternative 6: pulley & box

Alternative 7: Mini deliver robot

Conclusion:
From these 7 alternative prototype ,we entirely have choosen Alternative 5: Tube & tray/slide as our primary design hitherto refer to pugh diagram..

Possible circuit:

There are two ways of constructing the voltage divider,with the LDR at the top,or with the LDR at the bottom

Below is the circuit for IR sensor

The basic design of the infrared proximity sensor

PROJECT DEVELOPMENT-WEEK 3 & 4

2009-08-19T01:34:00.001+08:00

Since we are in the week 3, we have to develop the model. We decide to advent the intelligent food distributor robot using the track like in the diagram below rather than using line following that we have decided before because of some modification in our design. So,the project still in under progress.

(Client Request Medium)

1. Button(Bulb)
This type of button is made from simple a switch where it is connected to a bulb. By assuming the use of light sensor, the sensor attached to the robot will sense the light as white spot as the rest of the track is black. Whenever the client switches on the bulb, the robot that as is in movement will stop at particular spot (light on) and distributes the food.

2. Slide Card
This idea is the degrading version of Bulb Button where the light sensor is detecting the white card as the client slot the card under the track upon requesting the food.

3. Infrared Button.
This Button is quite advanced in its class where the receiver in the robot will detect the signal sends by transmitter when the client pushes the button.

4. Remote Control
The same concept as infrared Button and the different is instead of button, it will portable like remote controller.

5. Bluetooth Phone
The idea of this medium is enable client to request upon pressing his/her hand phone.
