Week 2

System's Integration (Design)

• System’s integration has been working on finishing the frame of the robot. 
• They looked at Team 118’s robot, which has a great intake ball system.
• We will be pursuing this system!
• Check out the link on the right! 

Team 118's Design

The Ball Picker-Upper (Modified)

• Mechanical Fabrication
  • PROTOTYPES!
    • The Ball Intake Systems
      • So as we stated in our last blog post, our top priority is the lower power port. We want to be able to pick up balls from the ground in large quantity and then funnel them.
      • Our first prototype failed epicly, so we modified it.
        • youtube.com/watch?v=yeKlx9b9iKE
        • This did work. However, we would like to create a prototype that centers balls as it enters, so we do not need to add an inner mechanism.
      • Our second prototype was a conveyor belt style. We started a prototype with flexible tubing that we planned to have move in a conveyor belt style. We were going to have this on either side of the ball to lead the ball up the double-sided conveyor belt.
        • (Look at the pictures. I know that’s a confusing explanation)
          • This is one half of the conveyor belt. (below)  
• This is how we viewed the mechanism as a whole (on the left)
• This design was not chosen because it is not space efficient 

• The next ball collector prototype works as a funnel. In theory it is in the shape of a trapezoid
  • Gets many balls in and then funnels them back because we can be carrying 5 balls at a time.
• However, we will be trying out a similar design to the Everything bot’s design team 118 The one I linked in the design section. Check it out!
• The Climber
  • We have the same design as last week, but we hope to work on an elevator for it soon!
• The Chassis (so far)

• Control Systems
  • They have been working on the pigtail three Andersons to connect the motors to the battery
• Fundraising
  • They have been working more on our awesome business plan
    • SWOT analysis!

• Outreach
  • This week we worked on Chairman’s essays and activity ideas for this year’s FIRST Theme for FLL—city planning! We have tons of great ideas check them out below.
    • Check for more next week!
