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.

title Mass Measurements
The mass of each of the following items should be recorded: Description Measured Mass (kg) Expand title Chassis (MR22-DT-A0014) 7.10 Expand title Differential Bar (MR22-DT-A0007) 1.40 Expand title Suspension Bar (MR22-DT-A0015) *Weigh and record each suspension bar separately 2.25 Expand title Wheel Module (MR22-DT-A0030) *Weigh and record each wheel module separately 3.05 Expand title Electrical Box (MR21-EB-B-Ahu) *Weigh ebox with all interior components (fan, jetson, odrives, etc) and wiring *Ensure that proper adapters are installed 2.30 (Empty) Expand title Battery Pack (P/N TBD) To be revised when proper battery pack is selected. In mean time, measure, weigh, photograph and document whatever battery solution is installed on rover Expand title Full Drivetrain Assembly Measure and weigh a fully functional drivetrain (no gimbal, all components described above installed, wired and functional) 33.5

title Dimension Profiling
The overall dimensions of the drivetrain should be recorded. Competition Constraint: Drivetrain must fit in a 1.2m cube Image RemovedImage Added Measured Length: 1.16m Measured Width: 1.18m Measured Height:

title 1m Drop Test
THIS IS A DESTRUCTIVE TEST, AND SHOULD ONLY BE PERFORMED AFTER ALL OTHER TESTS HAVE BEEN COMPLETED. PLEASE CONTACT Austin Tailon Huang IF YOU WANT TO RUN THIS TEST Test Details Fully assemble a functional drivetrain (drivetrain, EMPTY ebox, wheel assemblies, battery pack, no gimbal) Drop assembly from 1m height Observe any mechanical failures, failed wire connections, broken components, etc. Determine if drivetrain prototype is capable of being controlled at the same efficacy before and after drop Take video footage of drop with slo motion camera (phone camera is probably OK, just frame the video from multiple angles)
