Today was winter ball so we started at 11 since we had to clear out at 7 vs. our usual 8. The field is almost done. Both belly pans were finished, and most the plates were completed. CAD finished the mcmaster order. Not to much other than that.

The belly pan was attached and riveting to the second drivetrain today. We ran out of rivets again but we got some from 115 and should get more when our mcmaster order gets here. A lot of stuff arrived today, including our vex order, plastic for the electronics, and the cube covers. It took a pretty long time to cut out all 100+ of the bearings we ordered. The belly pan was completely attached save for a couple rivets, and we mounted all the wheels and chain we can. Over on the CAD side of things we fixed the intake issue so I am pretty happy about that. No pictures today, oops.

We had a rest day, and brought some switches and a monitor out and played mario kart and various
other games, including risk. It was very fun, and we had a lot of great food from the parents. CAD team
continued their work on the robot, and will hopefully have a model done by Wednesday. Not many
pictures today…

Friday we just kept machining. We have been running the CNC and mill pretty much non stop the 11th and have made a lot of the parts. With that, we always have to have a student ready to cut out the parts and sand the tabs down so it is pretty loud in the lab. We have been putting together the big order for everything we need and we are almost done with it. We need to get those ordered ASAP! CADing has been putting the finishing touches on the robot…

Today we had another productive day. The machinists worked pretty much the entire time milling gearboxes. The belly pan was started, which took a while to cut since we are not using the cnc router for it. Programming finally got their offseason bot and were practicing current limiting and using the fancy versaplanetary gearbox encoders. The field is nearly done, and our big vex order is arriving Tuesday.

We finished CNCing the pretty much all the plates and we are working on the elevator bearing plates.
They have been laid out really nice in CAM so it is really easy to cut them out and sand. The second
belly pan had its pockets cut out and will be attached to the robot tomorrow. The vex order should be
arriving tmr evening so we can sort and add those to the part inventory. The lathe has also been running
a lot, as there are a lot of different shafts on the robot that need to be cut to the proper length.

During our Monday off for MLK day we had a meeting from 12-8. Electrical finished wiring up the e plate
for the offseason robot, and Joel started getting code loaded on it to test PID loops, encoders, and
current limiting / detecting. They ran into issues getting the talons (motor controllers) set up and
eventually traced it to the leads on the CAN wires not being stripped enough to make a good connection.
Over on the mech side of things the team got a lot of good work done on the prototype and field. They
are pretty much replicating what I have in CAD right now so it will be good to test it in wood before
making it out of metal. Patrick / Rohan spent a lot of time machining, and the drive rails and a number of
other parts of the drivetrain are done. CAD working on a new cam system for the elevator, as well as
getting the gearbox for the elevator set up properly.

Not much different happened today, the majority of mech worked on assembling this giant field. The
programming team started work on our part number system, which I am very thankful for. We will be
able to enter a part number into a search bar and the info about it is pulled up including a screenshot of
the part. This will integrate nicely with the OnShape built in BOM for increasing efficiency. CAD team is
chugging along, and we have our elevator parts pretty much cadded up, as well as the crazy 4 775 pro
elevator gearbox. Tomorrow should be a chill day with only machining and cad meeting, the rest hanging
out.

We had a very productive meeting today, getting a lot done and moving us closer to following the schedule. Joel and the programming team worked on programming our offseason bot, and electrical spent more time getting the e plate finalized. CAD made some minor changes, but I ended up helping a lot over on the fabrication side of things. We are even closer to having the field completed, and have the scale arm complete. The manual and CNC mill were running pretty much the entire time, getting the 2x1 milled for the drivetrains. We now have both drivetrains riveting together, along with all the drive shafts. Tomorrow we will work on the belly pan as well as the gearbox. We also got our intake working reliably.

After the 3 day weekend we all got back into the lab for a pretty productive day. We had our first
all hands meeting and it was good for the team to see each subteams progress. No one had
any questions or comments which we should try to address for the next one. We should hold
them weekly on Thursdays. On the CAD side of things, we have been making good progress.
Aarzu finished the elevator supports, which we can use to mount some e components which will
be nice. Mech continued working on the field, finished the drivetrain 2x1 parts, and Rahul is
almost done with prototype V3. Joel has been working updating the firmware on the robot to
make the workflow faster when we get the e plates in.
