So so close to fully modeling out 3D printed pieces for the Flywheel/Intake Subsystem. 3D printed out some test pieces with slight difficulties. Cut hex shafts semi-straight to length according to the CAD model. Finally ordered 2D Lidar.

Like yesterday’s devlog, today was mainly a modeling day with getting the collars, spacers, inserts, and belt pulleys on the shafts. I also designed a top support plate which will also be where the motors are attached, which I’ll work on tomorrow. 

While I worked on the CAD I had printing some test shaft collars and inserts for the flywheels. Printing these items ultimately was due to how long it would take for real metal ones to ship and with the deadline being tomorrow there wasn’t much time. But there were some issues in printing today possibly due to using brand new filament and I might have refilled it wrong. 

After fully modeling out how the shaft of the flywheels would look like I cut them out of a stock ½” hex shaft at 4” long each. I also cut out the shafts for the intakes at 8.25” long each. Yet I don’t think it will be done by tomorrow afternoon as I’m still unsure when the cut and bent sheet metal will be done and it will take a while to print every piece needed.

Lastly I bought a 2D Lidar so that next week I can give the robot true vision with it being able to always know where the cones are not just based on how tall they are in the video feed.
