Task:We 3D printed a chassis with gearing ratio made for  speed not torque

Time spent: 1 hour

Challenges: The axles of the front of the car kept slipping messing up the gear alignment

Task: We 3D printed wheels that were lighter and more efficient than the heavy wheels that we had before. (First Design)

Time spent: 1 hour

Challenges: Getting the wheels to fit the axels due to the small hole for them

Modifications:

03/01 Team Members Present: Cooper S., Nick H., Tristan T.

Task:We decided to scrap the front wheel design to put them into the center front near where the loop goes for the wire and 3D printing a new chassis 

Time Spent: 1 hour

Challenges: the alligator clips for the battery pack kept detaching from the wires

Modifications

Task: Changed the wheels from a small design to a large 3D printed rubber wheel with a 3D printed inner hub.

Time spent: 1 hour

Challenges: The 3D printer was broken so we couldn’t print anything

Modifications:

03/22/24 Team Members Present: Nick H., Cooper S., Tristan T

Task: We made a new 3 wheeled design that has canted front tires and the motor connecting straight to the rear tire. We also mounted the solar panel above the chassis with wooden dowels.

Time spent: 15 min

Challenges: limited time for the meeting to work today.
