General Notes

Lightning talks
- Introducing lightning talks starting next week so we can be cool like the other subteams
- Opportunity to learn about a concept, tool, mechanism etc that can be useful in design
- E.g. SolidWorks tips, four bar linkages
- Open to suggestions for topics!
Trello
- We would like to try moving to Trello for all major mechanical projects
- Already using Trello for drive train
- Please update your assigned parts of Trello when you can
