Mechanical lift - There will now probably be 4 telescoping tubes (not 3). There are 3 possible hook designs. To do: make sure all pieces of the winch are in Inventor, assemble it all, and figure out the mounting point. Need to order stuff from McMaster-Carr.

Electrical - Went through old BOM and started modifying it. Added stuff to shopping list. Took off Victors and added spike relays instead for kicker (we probably don't need speed adjustment there). Need to correlate with Mechanical - sensors for kicker position, winch, etc.

Drivetrain - Parts are in, robot drivetrain will be built today! Weight estimate is about 50 lbs. for the drivetrain. Brackets need to go on the bumpers this year, because the allowed bumper weight has been increased to 20 lbs. That saves weight on the drivetrain.
