Activity Log


Saturday Week 1

Jonathan Farnham

  • Kickoff
  • Prelimanary ideas developed by drive base team
  • Areas of concern
    • Ramp to H1: 3 inches
    • H2 height above bumpers
    • Drive base will never scale H3

Sunday Week 1

Jonathan Farnham

  • Developed four inch wheel prototype
  • DriveBasePrototype1.jpeg
  • Used field to test four inch wheels on ramp

 

  • Used cad to study wheels needed for H2
    • Tested 4,6,and 8 wheel configs

Tuesday Week 1 

By Jonathan Farnham

  • Decisions being made about drive train configuration
    • Wheel size decisions need to be made
    • Choice of  motor needs to be made: Cim or Neo
    • Number of wheels needs to be decided
  • Mr.C developed skid plate study for 4 inch wheel

  • Developed cad prototype base on variant of last years drive system

  • Waiting on decision from strategy about habitat 2 or habitat 3 requirement
    • Does drive base have to scale H2?
    • If we scale H3 then can we use smaller wheels on drive base?
    • Does drive base have to develop H2 solution?
  • Length of robot has been decided to be 34in.

Wednesday Week 1

Cad1-9-19.jpgCad1-9-191.jpgCad1-9.jpg

  • Making the left and right side of the potential drive base.

Thursday week 1

  • Worked on L channel frame

Uchannelframe.jpg

  • Began assembling belt drive in CAD
