Simulated Car Control in Proteus

Objectives

The objective is to use Systems Engineering practices to design the various subsystems (steering, motor controls, etc.) work correctly together.

Guidelines

The project begins with the identification of required part in Proteus. The microcontroller, DC Motors, sensors, H - Bridges, Joy Sticks (Potentiometers as voltage divider). A detailed study of unfamiliar components will take place after. Additional resources are available in the Files section of the Course Menu. You must integrate the subsystems and program the microcontroller to operate the car.

The course labs will provide information and focus on the subsystems. Nevertheless, each of you is expected to invest time outside of class to complete the project.

You will present your Simulated Car Control in Week 8. There will be more information provided by your instructor during Weeks 7 and 8.

A Project Manual is also required. The Project Manual requires the following information:

1. An Analysis of Alternatives showing the alternatives considered and a justification for the chosen alternative;
2. A Bill of Materials that includes the eventual cost of building the simulated car;
3. A System Description that shows the data flow between the system and the subsystems, and between the subsystems;
4. An Operators Section, which describes how to operate the system; and
5. A Testing Section, which shows the Test Plan and results of the testing.

Milestones

Week 1: Review the requirements for the Project Manual. The testing procedures that you develop as you build the subsystems will be included in the Project Manual.

Develop software to control DC motor speed. Develop software to control stepper motor. Use H-Bridge to control motors.

Week 2: Develop software to steer the servo motor.

Program the interface between the potentiometer (voltage divider) and the microcontroller.

Week 3: Perform overview of the Systems Engineering approach. Identify subsystems to meet system requirements.

Week 4: Use voltage and current monitoring to assess the power requirements for each subsystem. Monitor subsystem power voltages while the system is operating to measure the amount of feed through and determine if interference is present.

Week 5: Determine the timing requirements for data to and from the subsystems. Choose the appropriate (interrupt or polling) techniques.

Week 6: Determine the requirement for a networking capability. Consider software routines to allow communication between systems and subsystems. Evaluate subsystem communications to ensure that requirements are met.

Week 7: Perform final testing of the project.

Week 8: Don't forget to submit your Project Manual and your lab.
