Electrical board CAD:

Our 2024 robot Synthwave for the Crescendo game was capable of all elements of the game except the trap.

Some of the mechanical design highlights are as follows:

  • Absolute encoders on our compact 3D printed swerve drives
  • Our fastest robot
  • 3D printed suspension treads
  • Robust – no breakages (except when a robot arm came down on our breaker box cover and broke it)
  • No mechanisms outside the chassis perimeter
  • Under 14.5” tall in starting configuration – permitting maximum speed with no tipover.
  • Through robot game piece handling
  • Under bumper game piece intake
  • Single hook for most reliable climbing
  • Articulated & sprung hook to eliminate any moment on the arm while hanging on the chain
  • Special hook profile to prevent slipping
  • Lift arm elevated by cannon, reducing motor requirements.
  • Compact needle roller bearings held by 3D prints for lift arm extension
  • Clamshell style 3D printed cable management for quick changes or additions.
  • Strong torsion springs for cannon rotation assist
  • Sprung loaded intake roller assembly raises up for greater ground clearance when not intaking notes.
  • Dual belts for note manipulation
  • Two servo operated locks prevent post-match drop (and missing the climb)
  • Two screws total for bumper removal.

This year we moved from LabView to Java. A Github link to the code is below:

As always, questions and comments are welcome.

I love the decision to have the dual RSLs, also the electrical board is great!

What can I say? I’m a slave to symmetry!
Thanks for your comments.
BTW, the CAD for the electrical board was completed in it’s entirety by a female student (who also happened to be our team captain).

BTW, if you are interested in just the 3D printed swerve drive, use this link:

And if you are interested in the 3D printed suspension treads, use this link:
