D-Bug #3316 Offseason CAD projects

During the offseason we at D-Bug ran CAD projects to get our new and veteran CAD sub-team members ready for the new season. Here’s a taste of what we got done:

** - Two Stage Elevator:**

  • 2 stage Cascade elevator, rises over 2.2 meters in 2 sec.
  • powered by 2 775Pro motors through a 1.63 VersaPlanetary gearbox.
  • Power transferred by #25 chain in all stages.

** - Butterfly Module:**

  • Butterfly drivetrain with 4 4" omni wheels and 4 2.5" Colson Performa wheels
  • Running at 13 fps in omni mode and 6 fps in colson mode.
  • Switching between modes by 4 pistons.
  • Compact design takes up minimal volume

** - Basketball Shooter-Turret**

  • Designed for standard basketball
  • Turret rotation through #25 chain, driven by Bag motor
  • Moving-Hood for multiple (unlimited) shooting angles, driven by window motor
  • 8" AndyMark (rubber threaded) Fly-Wheel shooter, driven by a CIM motor

We will be happy to receive any comments, questions and constructive criticism!
Stay tuned for information and CAD of the 4th mechanism of a telescopic arm

I can’t open the files. Can you check if the permissions are public?

Should be fixed now. Let us know if you have any problems opening them.

I have a few questions about your designs.

For the two-stage elevator, I see how the lower elevator is linked to the 775pros, but how is the top elevator linked?

For the basketball turret, what motor is driving the non-CIM pulley set? I would assume it has a built-in reduction or the shield would go way too fast. Also is there any plan to have a pot on the shield? And what holds the pot on the BAG? I assume it has something to do with the floating piece of metal next to it.

  • The 2nd stage is driven by another #25 chain which is connected to static profiles (So the distance between the 2 stages is constant).
  • Something wrong went with the stp file, but the 2nd pulley set is driven by a window motor, and a pot should be attached to it.
  • The hole turret rotation will be controlled by a pot and a limit switch for Match-Beginning-Calibration.
  • The floating plate is actually part of a tension mechanism
