Week of 2/7/22 - Weekly Report 16

Plans for next week:

• Continue Testing Raspberry Pi PWM signal controls for motor, brakes and servo.

• Develop standard code that allows each individual module to control the smart car.

• Work on individual Modules.

Group Meeting memo:

• Discussed the generation PWM signals using a Raspberry Pi.

• Discussed test procedures for PWM control signals focusing on safety.

• Continued discussion on PCB design

Project Progress

Quinn:

• Worked on testing PWM signals generated by the Raspberry Pi 4 B.

• Calculated required frequency and duty cycle for smart car controls and verified they operation in practice. Noting: that the duty cycle of the PWM controlling the servo directly relates to degree/direction of wheel rotation; that motor requires minimum level of torque to operate smoothly that once reached increases in duty cycle proportionally increases speed.

Jordyn:

• Adding CAN bus connections to Eagle

• Reviewed new CAN Bus design

• Looked at other other options besides PCB for CAN Bus

DJ:

• Assisted on testing the PWM signal generation and control of the car.

• Next Weeks Plan: Test the Arduino Nano using the ACC algorithm.

Jacob:

• Tested the PWM signals used to control the car

• Got both the servo motor and motor to work and will work on getting the specific duty cycle requirements for each

• We need to set up the code so that the other modules will be able to control the car through the raspberry pi main controller.
