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.
Scaler Pivot Arm:
Use Versaplanetary 100:1
12 tooth sprocket on motor shaft driving a 42 tooth sprocket
3. Update 1/26/16
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.
This is the actual arm we designed.
