Engineering Notebook – 09/27/2018

Attendance:

Alex, Charles, Cameron, Drew, Zach

 

Goals:  

All

  • To start creating a prototype hook, lift, claw, and drive train.

Meeting Notes

The team split up into three groups

  • Charles and Cameron:
    • Scratched their idea for using a gear with rubber bands to intake the minerals and started to design a new mechanism that had a basket that would scoop the minerals. Then slide them back on a linear slide, then up and dumped backwards into the cargo hold.
  • Alex:
    • Started programming basic driving codes to get a head start on programming for the season
  • Drew and Zach:
    • Finished making the linear lift and attached it to the drive train. After that they put on a motor and started testing it. The lift worked.

Goals:  

All

  • Watch videos of robots in three days to get ideas for our robot
  • Design and Prototype Mechanisms

Meeting Notes

  • Charles brought a model of a design where 2 rubber bands push down
    from on top of a silver mineral, so they bend out to pick up the ball, but the ball is
    too light to fall out. This idea was decided against because it can’t pick up cubes

  • Our team split into 3 groups.
    • Charles: Ball Pickup
      • Put 2 gears on an axel and put 8 rubber bands attaching corresponding
        holes of the gears.
      • Gears will spin causing the cylinder of rubber bands to rotate and grab the minerals in.
      • Picked up minerals will go into bucket on linear lift.
      • Since the radius of the gears is smaller than the height of the silver mineral, the ball pickup may have to be higher than the main frame, depending on the height of the wheels.
      • The motor can go above the ball pickup and use gears to rotate the ball pickup.
    • Alex and Cameron: Drive Train
      • Started with H frame with 2 bars in middle instead of one.
      • After discussing with Zach, and Drew, realized ball pickup would need more room.
      • Changed frame to A frame.
      • Ball pickup will go in gap in front and the lift for hooking on to the
        lander will go on the back.
    • Zach and Drew: Lift
      • Planned lift design as a two-stage lift. Started to build lift by adding

 

Engineering Notebook – 09/13/2018

Attendance:

Alex, Drew, Charles

Goals:

All

  • Identify which points the team wishes to go for and discuss which mechanisms or types of robots are best suited to achieve these goals
  • Made a list of all possible ways to score points
Autonomous Points Tele-Op Points End Game Points
Landing 30 Points Mineral in Depot 2 Points Latching and Lifting 50 Points
Claiming Depot 15 Points Mineral in Cargo 5 Points Parked in Crater 20 Points
Bonus if glyph is in correct column 30 Points Partially in Crater 15 Points
Parking 10 Points
  • We determined that the hook on the lander is 22in off the ground and the lander’s top was 29.5in off the ground.
