2025 Reefscape

             This week, we made huge improvements to be well prepared for the East Bay Regional (EBR).              Since we finished CADing last week, we were able to start assembly immediately. This week has been packed with testing, improvements, and strategic discussions as we gear up for upcoming competitions. From refining intake mechanisms to optimizing our scouting app, every detail is being fine-tuned to ensure peak performance.              We assembled spare components onto the beta bot for testing purposes, ensuring reliability and durability under competitive conditions. Additionally, minor improvements were made to the scouting app to allow for better usability and efficiency. To address control system stability issues, adjustments were made to the plate under the CANivore. On Wednesday, we focused on improving the practice field to better simulate real competition environments. By Friday, we had fixed the camera mount to ensure better visibility and alignment during matches.             A new intake system with a larger wheel was implemented to address the issue of pushing the coral away during both practices and competitions. We are currently testing different wheel sizes, comparing 5-inch and 3-inch wheels, while evaluating the impact of material flexibility under high-speed rotation. Significant progress was made [...]

             Returning from the SAC regional, the team made notes to get ready for the next competition, the East Bay Regional (EBR).              The team met for a competition debrief in the beginning, which included discussion of competition performance, robot improvements, and logistical improvements for the next competition. We realized that driver practice and tuning auto routines would be the main focus of weeks 4 and 5.              Another meeting on Friday, the team began fixing a few minor flaws in each subsystem. Per the competition debrief, we decided to replace a MaxComposite plate for aluminum on the outtake. Along with the outtake, the team had agreed upon improvements to the intake, gearing the first roller faster to allow the driver to intake coral at higher speeds, and adding a larger wheel to the center roller to better vector the coral in its horizontal orientation.              The team additionally worked on improving the energy chain on the elevator, as it had previously caught on the hard stop, which prevents the outtake from fully stowing. Furthermore, the software team has been working on speeding up all the movements of the elevator and wrist, as well as tuning the vision alignment [...]

On Monday, the team made significant progress in assembling key parts of the robot. With our new designs coming together, we focused on refining vision alignment by retesting the angle and direction of the camera for auto on the old robot, ensuring it properly detected AprilTags for more precise movement. Meanwhile, our driver continued practicing, further improving his skills to maximize our robot’s performance on the field. The control systems team worked on crimping the e-chain. Additionally, we finished assembling our third elevator of the season. We also had many students in the classroom building spare subsystems for Vantage and disassembling subsystems from the older iteration for spare parts. They labeled them and packed them into our pit and trailer. At the end of the day, we finished wiring and tested the new coral and algae scoring mechanism on our field, running a few cycles to check for reliability. We also worked on organizing the pit, making sure everything had a designated spot to make setup easier at competition. We checked our packing list multiple times to ensure we had all necessary tools and backup parts. Once everything was prepared, we loaded up our trailer and sent it off to the competition. We also posted our robot teaser, which was exciting to finally share after all the work that [...]

Preparing for Sacramento, we've upgraded our robot and strategy based on Pinnacles insights. Here's our progress. After lots of hard work over the past week preparing for and attending Pinnacles Regional, we gathered together on Wednesday to debrief about our performance at the competition. During our time together, we split up into three groups in order to evaluate the aspects of our performance - the pit team, strategy team, and scouting team. For the pit, everyone agreed that our indexer was our weakest subsystem due to the 50% jam rate, even though we got lucky and it performed closer to a 95% rate at Pinnacles, we wanted to learn from our mistakes and continuously improve the robot. We also rewatched all our matches from Pinnacles, and compared our scouting data and saw that our outtake was outtaking the coral much faster than we needed at the angel of our outtake, so we redesigned it with the help of the strategy team and our driver Arman who did a phmonel job at Pinnacles. Lastly, the scouting team has undergone many big decisions and renovations as well, such as an automatically selected ‘Leave’ and an alert to remind scouters to click from auto to teleop, this is allowing us to improve the accuracy of our data. We are also trying to [...]

Leading up to the event, our team was in full-on work mode, focusing on three key areas: refining our autonomous routines, perfecting our coral scoring, and ensuring our climb was rock-solid. Our programming team worked tirelessly to get our auto consistently hitting Level 4 during practice, while the mechanical and design teams collaborated with the drive team to fine-tune our climb along with the different communicative elements of our PS5 controller. Friday was all about practice matches. Our auto performed somewhat consistently, hitting Level 4 and giving us a strong head start in every game. Even though our vision system wasn’t fully operational, our driver delivered an outstanding performance on the field. And our climb is currently 8th in the world. Thanks James! (Our human player was the main designer behind it). It worked flawlessly every match, securing crucial endgame points. Seeing all our hard work pay off was an incredible feeling. Saturday: Quals and Quick Fixes Saturday’s qualification matches brought intense competition. We noticed an issue with our coral intake and outtake system—corals would sometimes slip or drop during the switch from auto to teleop. We also noticed that the angle on outtake wasn’t working well for L4, messing with our auto and teleop cycles. Fortunately, our new scouting app and video reviews helped us quickly identify the [...]

             This week, as we near the end of our build season, we had to commit to get our robot done in time and done well. We started the week with a friendly visit from two great teams: Quixilver and Goldstrikers. We discussed robot design with them, figuring out which methods worked for the other teams.   We also had a lot of improvements to make on our own robot. Our robot was a little overweight, so we needed to figure out how to add some weight reduction. We changed our plates to be thinner and gave the belly pan some grates. This resulted in a mad sprint to machine and assemble our robot, which means we now have three competition drive trains! An Alpha bot, Beta bot, and our final robot, named Vantage!              We began to remake the robot, with the overweight one being used for driver practice as the new one continues to get built. This helped our weight problem tremendously, and we should be underweight now.             Furthermore, we had a lot of subsystem changes. For our outtake, we shortened the bottom plate and then bent it so the coral would be deposited from the indexer more smoothly.       [...]

             We started the week by assembling the final subsystems of our robot. We mounted and calibrated the elevator, worked on bumpers, began manufacturing parts for our intake and indexer, and mounted the outtake onto the elevator. Meanwhile, our Software team created code for each subsystem to streamline the final weeks of integration testing before our week 1 competition.              On Wednesday, we began assembling the deep cage climb mechanism. Our manufacturing team quickly made the necessary parts, allowing the assembly to proceed smoothly. Our Software team also continued refining our intake and indexer code, and our Control Systems team attached the energy chain to our elevator.              On Saturday, our hardware team calculated that our robot would be overweight. They immediately brainstormed creative ways to reduce the weight. They decided to switch the Drivetrain rails from 1/8 to 1/16 inch, the Battery belly pan from 1/4 to 1/8 inch with an additional weight reduction grid pattern; the polycarb cover for the control system board was also reduced from 1/8 to 1/16 inch. Manufacturing for these changes began immediately. The upside is the team would now have a beta bot that will be used to test and finetune near-final subsystems, and auto routines, and allow our driver to continue to practice on our practice field while [...]

             With our first competition just around the corner, every second counts. We pushed forward on all fronts during week 5—manufacturing, mechanism assembly, coding, scouting, and more—all while making exciting progress on our robot and beyond.              On Wednesday, we held a critical design review. We discussed minor changes to our mechanism designs to reduce size for better packaging, improve coral lifecycle from intake to outtake, and keep our robot weight below 115 lbs.              Our scouting app team has also made significant progress. They implemented data visualization in the form of charts, which made the analysis process quicker. Additionally, we finished assembling the elevator and tested its voltage to check its efficiency.              Our vision team continued to perfect their integrated vision assist when approaching the reef to score. With the new bumper rule changes, the team has decided to use EVA Foam over traditional solid-core pool noodles. The EVA foam has proved easier to work with, as we were able to order 40 x 80 sheets and cut them down to the required size for baltic birch bumper backings. This year, we are making practice bumpers in addition to our comp bumpers.           [...]

             Over the course of this week, our team has made steady progress toward finalizing our Reefscape competition robot! Our driver, Arman, continues to practice with the Crescendo competition robot, Alphabot, and the Reefscape competition drive train. Arman has been testing out different controllers, he recently settled on the Scuf Reflex FPS controller.              Eric and Max had another productive week working on the scouting app. The UI was finalized, AI features were added, and it is now able to record scoring for Auto, Teleop, and Endgame!              While we are mostly done with the prototyping phase of our build season, our CAD team is working hard to finalize the competition robot CAD and drawing files for handoff to the manufacturing and assembly teams. The Reefscape robot's weight limit of 115 lbs, is proving to be a bit of a challenge, so our design team is looking for creative ways to reduce the weight of our robot and to improve the packaging of the subsystems onto the swerve drivetrain.              As mentioned in last week’s blog post, we decided on a 4-degree angled elevator mounting to simplify the end effector design. The manufacturing team has completed manufacturing all the [...]

             Following a restful MLK long weekend, we continued with data testing, creating many new prototypes, and making some important decisions. On Tuesday, our Design Voting Council (DVC) voted on different orientations of the elevator. They settled on an elevator oriented on its side, angled at 4 degrees, due to its benefit of taking up less space. We also started planning which awards we are going to pursue, working on our tech binder, and ordering apparel. We ended the day with our weekly stand-up presentation.              Throughout the rest of the week, we continued prototyping various mechanisms for deep climb, coral intake, and our autonomous routine. During this time, we decided to test an offset bicep climb to see if it would be possible to place the mechanism on the side of our robot. Through many trials, we observed that the bicep arm with an offset often slipped off the cage.              In parallel with the deep cage climb and autonomous path testing, our team has started testing intake from every orientation. Depositing the coral into the trough (L1) has met our functional requirement of 95% or greater for scoring L1. We also tested stacking coral in the trough to maximize our earned points. [...]
