Robotics Log 03 - Prototyping Day 1
Starting on Prototypes & KitBot
Mon, January 12 (4:00 PM - 7:00 PM)
At this meeting, work started on prototypes. Since the CAD lead already finished designing the over-bumper intake, it was cut on the CNC by the end of the day. Our mechanical lead (Link) helped some other mechanical members (and Kylie) assemble the KitBot. Unfortunately (after the meeting) they realized that instead of building the square drivetrain, they accidentally are building the standard one, so some work will have to be corrected on Tuesday.
My prototype (the tube indexer) was actually almost completed. I put holes for bearings and woodscrews to hold a piece of polycarb into a piece of plywood. A mentor tried to explain to me how this was actually a bad prototype because it didn’t test the effects of balls pushing against each other, even though that wasn’t originally the point. We decided that we will design and build a different prototype that is much longer (5-8 fuel long?) and goes at a 180-degree angle rather than 90, and with a belt in the center.
Meetings until Scrimmage: 41
Things Completed at This Meeting:
Mechanical:
- Started assembly of KitBot Drivetrain & Tube Indexer
CAD:
- Started CAD of Spindexer & Hooded Shooter
- Finished CAD of Over-Bumper Intake
- CNCed Over-Bumper Intake
Media:

Scrum Board:
| Prototype: | Tasks: | Test By: |
|---|---|---|
| KitBot | Build (Steps TBD) | Thursday |
| Climber | Design -> CAD Design -> CNC -> Build | Friday/Saturday |
| Hooded Shooter | Finish CAD -> CNC -> Build | Friday |
| Over-Bumper Intake | CNC -> Build | Friday |
| Spindexer | Finish CAD -> CNC -> Build | Friday |
| Tube Indexer | Gather Materials -> Drill/Cut Holes -> 3D Print Spiky Wheels? -> Assemble | Thursday |
Team Goals for Next Meeting:
Mechanical:
- Make more progress on KitBot (fix drivetrain to be square)
- Assemble over-bumper intake (~80%)
CAD:
- Finish CAD for hooded shooter & spindexer
- Come up with plan for climber, make progress with CAD (at least 50%)
My Goals for Next Meeting:
- Either explain to mentor how my prototype is good or design new one which will be CNCed
