Drivetrain Testing Plan

Constraint Validation

Listed below are key metrics that must be measured to ensure our design means competition requirements. This data may help with improving designs, but mainly is intended to verify constraint conformity. These tests will require no support from software, firmware or electrical.

The mass of each of the following items should be recorded:

Description

Measured Mass (kg)

Description

Measured Mass (kg)

 

7.10

 

1.40

*Weigh and record each suspension bar separately

 

2.25

*Weigh and record each wheel module separately

3.05

2.30

(Empty)

 

33.5

Power Performance Testing

Listed below are tests designed to quantify and understand the motor performance of our drivetrain. These metrics are intended to provide hard data on basic electro-mechanical performance of the drivetrain, and is mainly intended to validate the following items:

  • motor spec’ing calculations and assumptions

  • power draw estimations

  • basic driving functionality

These tests will require electrical and firmware support, as well as odrive functionality and basic software to perform the following functions:

  • Independent and simultaneous control of all 6 wheel assemblies (on/off, and direction control)

  • Motor speed control

  • Logging of motor RPM, current and voltage (recording PWM cycling), preferably in CSV format

 

Competition Performance Testing

Listed below are tests designed to get a good understanding of how our drivetrain will perform at competition. This section will be revisited after the first set of testing is completed. For more details, please contact @Austin Tailon Huang .
