Working on slide presentation ( week 11 )

From the report on weekly 12th, I have basically done with the Flow Chart and the Block Diagram where I  can know what is the exactly function of the parts.I also added the comprising 3 type of motor and this is my finding;

• Servo Motor (SELECTED)  - Least expensive non-surplus source for gear motors. Can be used for precise angular control, or for continuous rotation.
•  Stepper Motor  - Consumes high current. Needs special driving circuit to provide stepping rotation. Cannot support heavy structure due to low torque.
• Continuous DC motor  - Requires gear reduction to provide torques needed for most robotic applications. Poor standards in sizing and mounting arrangements.

 I'm also doing  a comparison between Microcontrollers between PIC (Peripheral Interface Controller), Atmel AVR (8-bit microcotroller), and Intel 8051 (8-bit microcontroller). Function of this Sensor is to detect the obstacles while the robot is on the run.Below is the result of the comparison.

• IR sensor (Infra-Red) - Low power requirements with simple circuitry. There is no special or proprietary hardware is required, can be incorporated into the most integrated product
• Ultrasonic Sensor - The readings from an ultrasonic sensor can be distorted by Density, Consistency, Material

• Triangular-Based Sensor - High input is required. The sensing is very   sensitive and a lots of noise. The sensor is very sensitive and must always      kept clean otherwise it effect the accuracy of sensing. The operating     temperature is very limited and required external cooling system.

I have decided to choose  the IR Sensor because itt is simple and easy to operate. It is also  the most suitable for this project.
