In REBUILT™ presented by Haas, two competing alliances are invited to score fuel, cross obstacles, and climb the tower before time runs out. Alliances earn additional rewards for meeting specific scoring thresholds.

During the first 20 seconds of the match, robots are autonomous. Without guidance from their drivers, robots score fuel into their hub. Fuel can be pre-loaded into a robot, obtained from the human player, collected at the depot, or picked up throughout the center of the field. Some robots may also climb the tower to obtain additional points.

During the remaining 2 minutes and 20 seconds, drivers control their robots. Based on the result of autonomous play, alliance hubs will alternate between active and inactive, shifting gameplay between both sides of the field. Robots can collect fuel at any point in the match and may control any amount of fuel at a time. Drivers control their robots to score fuel into their hub while it is active and may perform defensive strategies or collect more fuel while their hub is inactive.

As time runs out, all hubs become active, allowing all robots to score. Robots can climb to the tower’s highest heights to score additional points and claim match bonuses to increase their position in the rankings.

The alliance that earns the most points wins the match!

    Teams (and people) we, well, appreciate Once again, I will second @dkavner’s comments and give my round of thank-yous: 2468 for being wonderful, organized, well-prepared captains 1756 and 3931 for being awesome partners and again to 1756 for somehow fielding pneumatics in 2026 4201 for getting our robot and pit there and for their moral and material support. They even lent us a spare Mk5n in the off chance that we’d need it or any of its parts in elims. @p_nguyen cheered and even helped strategize with us all during elims. 5199 for their additional support all through Champs. 5199’s […]

    +1 to the TPU 72D pulleys. This year was our first year running stubs and we decided to go straight for the 3D printed pulleys rather than being limited with certain teeth and tubing diameter with the WCP ones. Shoutout @Basuj for such a goated configurable 3DP stub roller and putting us on the 72D tech. Before we went full on 72D, we actually used Polymaker PA6-CF. However we faced two main issues with those stubs: 1. we still faced issues with the stub eventually cracking after repeated impacts/the flanges would snap off and 2. PA6-CF at the end of […]

    TorstenTortise: How important are the spokes of that pulley? Are they providing stiffness with extra walls or is it just for weight? Primarily weight, but aligning the walls in the load direction doesn’t hurt. Our other pulleys are standard and hold up just fine, I just printed this one like this as a test. Indiebot: We’ve had issues with sheering on our stub rollers, do you think this type of tpu would help prevent that? I don’t know how they would perform compared to PEEK but this stuff has crazy layer adhesion similar to other TPUs. We haven’t had issues […]

    guineawheek: TPU stub rollers? Apparently, a well-known NorCal team with similar resource constraints printed their stub roller bodies out of cheap 95a TPU (with the key being 100% infill and 4+ walls), and these had apparently lasted for ~3 events without breaking. Apparently, TPU has a tendency to dent rather than crack like PETG, making it kinda like SRPP but for 3d prints. Try 72d TPU. It’s even stiffer than 95a, easier to print, and doesn’t have to be solid infill (I personally use 5 wall 30% gyroid). It’s also AMS capable and just as durable as 95a. I repeated […]

    A seasonal review Let’s start looking back at the season, shall we? Our kickoff/early season analysis seemed really sound We correctly identified that: turrets were valuable for all the reasons we thought they would be dye rotors were both an optimal turret indexer but would require significantly more iteration resources than we could afford to pull off having good camera coverage would be critical for our strategy climb was buns we needed every single piece of aluminum we could get pocketed, pocketed Now, there were a couple misses. Mainly: we undervalued ball capacity we didn’t fully realize how strong the […]

    Things I did instead of watch Einstein One of the unfortunate parts of being division finalists is that we were too busy packing up our pit and getting food for us to actually get good seats for Einstein. And after checking whether I really wanted to be in the Archimedes seats with absolutely nothing there, I mostly decided I was going to do other things. Fulfilling a year-long promise First, I had to actually be in the Einstein stands for a bit I had been planning for nearly a year: That’s right. I brought a calibrated sound level meter to […]

    guineawheek: Also really appreciated the football-style field whiteboards to graph out strategy plays. This was by far my favorite thing their strat team did. I even took pictures. If we ever have a match strat team that consists of more than just one student and myself I would love to run things this way in the future. Here’s a pic I yoinked of the setup. Read full topic

    Galileo A7 We initially considered doing a picklist, because we had figured due to the oncoming scorch in our division we might be a first pick. I then tried metagaming it out myself, and at least by surface-level scouting and metrics like EPA or OPR it didn’t seem like we were gonna be a first pick, so I advised all of our (sleep-deprived) students to scrounge sleep as soon as possible. Additionally, I figured that any team that would even bother to pick us to begin with would have a strong scouting team and would know who else to pick. […]

    To clarify some of our issues: Q98 We didn’t lose the crimps on all of our cameras. We lost one of 12 crimps on each of two adjacent cameras, which was enough to mess up our vision. We decided to use Molex SL connectors for our cameras due to our poor experience with USB connectors last year. While this was a good choice, we didn’t spend the time to find and document the best practices for working with the 24-28 AWG camera wires. Our students are trained for working with 22 AWG CAN wires. They struggled with the camera wiring […]

    Championship qualification matches – Day 2 The rather annoying thing about our robot is that it always seems to work great for 5 matches, break for another 5, and then work again for the last 5. You could see this at OC (break, work, break), DCMP (work, break, work), and here (work, break, work again). It feels like after 5 matches our robot reaches its MTBF and then we need to fix everything again. But somehow, it worked out. Q73 Qualification 73 – FIRST Championship – FIRST Robotics Competition – Galileo Division This match went okay. We persisted under heavy […]

    guineawheek: The spare intake ended up using PEEK stub rollers May I ask why you chose PEEK over common materials like PA6 or PETG for this application? Was it for heat resistance, lower friction / no lubrication, or dimensional stability under load? Read full topic

    Championship Qualification Matches – Day 1 On day 1 of quals, our robot performed pretty well, despite the challenges. Q13 Qualification 13 – FIRST Championship – FIRST Robotics Competition – Galileo Division Despite 2813’s issues with vision in their first match and on practice day, they managed to pull through for this qualification match. We additionally had 931 focus on controlling balls as they fell into neutral and occasionally going to shoot, emulating a strategy we ran with 4201 back in SoCal. Altogether we were able to score over 600 points. One problem. Our opponents scored over 700 points. I […]

    So, um, how did this happen? Well, let’s start with practice day. First: get the robot and pit in the venue Thankfully, both SoCal trucks arrived on time this year. The 53’ truck with our robot in it arrived first, and the 26’ truck with our pit arrived a couple hours later as it had to wait in a much longer line to get in. While the FMA people were antsy about when they could unload their truck, we were all thankful that it had gotten here on time. Big thanks to @Joy4201 @Andrew_Kempen and @jjsessa for their work on […]

    I, uh, well, um, HUH?!?!?! After 2025, where we had built a fantastic robot that just wasn’t Champs viable, we had set a general goal to build a robot that would peak later in the season, and hopefully unlike last time, be pickable at the Championship level. We pretty explicitly wanted to emulate 294’s 2025 season where they had traded early event performance for lateseason success. And…well…the results speak for themselves. We have, by all measures, overshot this mark as not just playing in elims, but ending up as a division finalist first pick. We got one match farther than […]
