Notes

finding the ideal locations and distances is a lot of guess and check and would be more time consuming if not for Ha's drawing---USE IT!!! 

Work Completed

  • reassembled ramp using Ha's drawing
    • Cut ramp board to be 47 inches 
    • replaced the triangular hinge with a door hinge
      • in the drawing, the distance between piston and leg was too short (as we found out upon assembly), so piston could not fully extend, so we attached leg to where the piston is fully extended (~18.5 inches between robot-side of ramp hinge and leg hinge, ~15.25 inches between leg hinge and piston hinge)
    • mounted piston to leg 4 inches above the hinge 
  • tested ramp with new distances between piston and leg

Challenges

  • Like stated, distance between piston and leg was too short so the piston would not fully extend
  • the wheel does not touch the ground when the piston is not extended
  • the wheel does not tough the ground either when the piston is fully extended 

Work for Next Meeting

New stuff:

  • Move piston mounts further down ramp (away from bot)
  • Move piston mount on leg towards roller/wheel (it should be more than four inches above the hinge)
    • while moving both around ensure that the leg touches the ground upon no and full extension of piston 

Older stuff:

  • check the angle & test with nonadrive?
    • see how steep the ramp can go and the drivetrain can still successfully climb on
  • determine piston size for CAD team
