Drivetrain and Chassis Research (2021-2022)

Inspired by the Arm team's research topic list, here are some topics that I (Emily Adam) would like to look more into. Feel free to take any of my topics, join someone else on a topic, or add your own suggestions! In general, I think we should be researching our options, their pros/cons, and what is required to implement that technology. 


Topic RationaleKey Things to ResearchAssignment

Flexible frame styles

  • Understanding the variety of ways that the problem of drivetrain flexibility has been solved will help us grow our perspective. This will help us either A) come up with a brand new design or B) find an option that really suits our team
  • Styles used in industry
  • Styles used by other URC teams
    • How did the team compute their drivetrain geometry
  • Analysis of drivetrain styles
Member styles and implementation
  • Different ways of styling frame members will have different effects on drivetrain properties such as stiffness, robustness, etc.
  • Want to optimize our drivetrain for these qualities as much as possible
  • What styles are used in industry and by other URC teams (i.e. tubes, T-extrusion, etc.)
    • What is the main method of manufacturing when working with them?
    • Generally, what strategies are used to assemble a pair of members?
  • Properties advantage vs weight

Wheel construction
  • Our wheels have a huge impact on how we interact with obstacles and the field in general
  • Polymer 3D printed wheels, metal wheels, balloon tires
  • Tread styles
  • Analysis of the differing wheel styles
  • Size
  • Shape (some teams use 'torx' shape)

Construction materials
  • Also contributes to drivetrain robustness
  • Large impact on rover weight
  • Construction material options and any unique fabrication processes required to use them
  • Potential procurement routes
    • Where might this composite be sold and for how much per meter
    • Potential sponsors? 
  • CARBON COMPOSITES

Drive system styles
  • Deciding the type of motors we want, the number we'll need, and how they'll be implemented will affect the EE plan for drive controllers
  • Viable motors, gearboxes, and motor+gearbox duos of different types and their pros/cons
  • Direct drive vs chain drive and how they are frequently implemented
