1. The Plan

We have come to the conclusion that the best method of scaling the castle near the end of the match is using a telescoping arm to latch onto the bar and then lift with the arm.  

2.  To Do

  • Figure out the measurements that are alotted to the scaler team.
  • Collaborate with the drivetrain team to ensure that those measurements will work well.
  • Design the telescope nesting arm.
  • Finish CAD work.
  • Select motors 

Scaler Mechanism to Lift Robot:

Two CIM motors

AndyMark Toughbox Mini with 12.75:1 Ratio

#35 Chain with a 12 tooth sprocket on the transmission shaft going to a 28 tooth sprocket on the scaler mechanism.  This is contingent on the gearing inside the scaler mechanism.

3.1  What we're working on

  • Design rollers/stops for the arm stages
  • Design lightning holes
  • Design motor mountings and figure out how to attach to the drivebase
  • Send parts to chamtek
  • Finish CAD work

3.2  Photos

This is the hook we will be using.
