DESIGN

Fail: Took lots of time to redrill mounting holes to move electronics to make the 2023 robot into a test drive base.
Fix: Design custom mounting brackets for all electronics that use a standard ½ inch hole pattern with 10-32 bolts. The 2024 bellypan will have a 1⁄2 inch hole pattern across it so electronics mount easily. Added embedded lock nuts to the 3d prints so electronics mounting only requires a single allen wrench.

Control System Mounting Bracket CAD (Onshape): Onshape

ANNOUNCEMENT

We will now be posting our updates on our new 2024 build thread: FRC 4322 Clockwork | 2024 Build Thread | Open Alliance

This is our team’s chain of command. We break our technical sections down into software, design, and fabrication. Our business/administrative sections are broken down into business, outreach/awards, and recruitment. For electrical stuff, both software and hardware come together to wire up the robot.

12/20 Update

• Routed RoboRIO to RPM (Nemo)
• Routed RoboRIO to PDP (Nemo)
• Routed PDP to RPM (Nemo)
• Mounted RSL (Nemo)
• Finished Result:

KICKOFF PREPARATION

• Cleaned our room and moved tables
• Mounted whiteboards onto walls

• Scheduled online trainings over student winter break
  • Onshape CAD training
  • Design Training
  • Electrical Training

12/17 Update

MECHANICAL

• Finished 4 MK4i Modules (SHUTDOWN)
• Mounted 2 MK4i modules (SHUTDOWN)
• Created standardized electronic CAD mounts for some electronics so they can be on the same grid mounting pattern

ELECTRICAL

• Wire managed all SparkMAXes, NEOs, Radio to RPM, and CAN loop (Nemo)
• Moved breaker mounting holes and mounted it down (Nemo)

• Mounted RIO and plugged in RIO power and Ethernet cables (SHUTDOWN)

12/16 Update

MECHANICAL

• Disassembled a 3 motor swerve MK4i and started assembling 2 motor swerve COTS Level 2 Mk4i

• Assembled MK4i module up until motor steps (8 and 9)

• Disassembled spare 2023 intake

SOFTWARE

• Finished creating an Autochooser for 2023 Robot(Nemo) drivebase
• Started working on 2024 MK4i swerve drive code

ELECTRICAL

• Made new mounting holes for PDP (Nemo)
• Mounted last 4 SparkMAX (Nemo)
• Mounted RPM, Radio, and RoboRIO (Nemo)
• Made pigtails/wires that connect to the PDP (Nemo)
  • Added pigtails onto the robot and attached them to the PDP
• Partially wire managed 2 SparkMAXes to their respective NEOs (Nemo)
• Wire managed 4 SparkMAXes to the PDP (Nemo)

12/15 Update

MECHANICAL

• Started disassembling 3 motor swerves & assembling SDS MK4i
  • Regreased large bearing with red jelly grease

• Finished up to step 5 of if SDS Assembly Guide

• Secured bumpers onto SHUTDOWN drivebase

• Filled gap between frame and bumper to make it fit tighter

ELECTRICAL

• RSL and Breaker still need to be mounted (Nemo)
• All SparkMAX’s connected to motors (Nemo)
  • 4 sparkMAX’s have been mounted, the other 4 have been positioned
• Connected encoders to turning motors and put electrical tape to secure it (Nemo)

Failure: 4 SparkMAX holders did not line up with the mounting holes (Nemo)
Fix: Made holes bigger and shifted them over in whatever direction needed so bolts would fit without having to drill out new holes (Nemo)

Failure: Found out that PDP was covering part of a RoboRIO mounting holes (Nemo)
Fix: Moved the PDP and redrilled new mounting holes for it
