             After exciting anticipation for the game reveal over winter break, we gathered to watch FIRST’s live stream. We then went straight to reviewing the game manual and brainstorming robot strategies. Our first few days of the season were spent honing in on our robot’s functional requirements and strategy. We also met with the FRC teams BREAD, GravitechX, and NerdHerd to get an outside perspective and exchange ideas.              After deciding our initial strategy, we researched design ideas, taking inspiration from past games and open alliance teams. Before committing to any specific robot design, the team split into Design Groups, each tasked with exploring separately to avoid the entire team fixating on just one design. These teams focused on analyzing scoring potential, identifying challenges, and understanding the game's nuances to optimize gameplay efficiency. Then, we reconvened to collaborate and discuss overarching designs to decide what we would need to prototype. We decided to prototype a ground intake that picks up coral from all orientations and a climbing mechanism inspired by Rust Hounds from Ri3d.              In conjunction with the prototyping groups, a separate group focused on designing the first iteration of our Alphabot. The Alphabot combines our off-season project, a two-stage cascading elevator, a [...]

             The new year means setting up for success, including organizing our Pit, managing operations, and handling new material shipments. Our shop manager, Ellery Han, has been cleaning the Pit and delegating tasks to sort last year's parts, screws, and miscellaneous items. A well-organized Pit is crucial for efficiency. With packages arriving nonstop, we order early to avoid delays and ensure we have everything needed for the Fall and Build Seasons. Students help sort and take inventory, ensuring each subteam knows what materials are available for their projects.              The operations subteam, in which all members are required to contribute at least 4 hours of admin tasks and additional upkeep work, is led by our new operations director, Claire Mayder. She’s been training new students and leads, applying for grants, and more. Our new communications lead, Jahnvi Bheemarasetti, assists Claire.              Our team fundraises the majority of its money in the Fall Season, this includes receiving money from sponsors such as the Wild Cat Foundation–our school foundation that raises money for school-related activities. Big thanks to them as well as all of our other sponsors! We’ve also had significant work done in documentation for operations to ensure efficiency in the build season and [...]

             This is the third year we have worked on the vision project. In the 2022-2023 season, we started the project and wrote code for pose estimation using April Tags. In 2023-2024, we mostly focused on improving the accuracy of our pose estimation, but we also started working on object detection. Our pose estimation was accurate enough to shoot into the speaker by the competition, but our object detection was not functional enough to use the competition.              This year, we are mostly focusing on object detection. The first step is imaging the Jetson Orin Nano that we plan to use since we currently need help finding the one we used last year. We encountered several problems imaging it and installing all of the necessary libraries, but we eventually finished. Our code runs but gets about 7 or 8 frames per second. We are currently trying to improve our framerate, and then we plan to mount a camera on our test robot to create and tune an algorithm to help the driver intake a game piece.              We are also training a practice model. Since FIRST released that there will be two different game pieces next year, we decided to use cones and cubes [...]

As February comes to a close, students have been hard at work during their break. Week seven has led our robot to progress nicely. All of our sub teams have been working hard to prepare for our first competition of the year, Silicon Valley Regional. This week, the arm, shooter, and intake have been mounted and wired onto our robot. Our subsystems were assembled separately and, when done, mounted on the drivetrain. We designed around serviceability and ease of understanding in preparation for competition. All power wires were labeled and routed separately from CAN and sensors for clarity in robot inspections, debugging, and replacing of parts. Wire connectors and extensions, for example, are all centralized in certain accessible locations to avoid having to access our protected upside-down control system board. The programming team has been successful in identifying the initial x and y velocities for shooting while moving (SWM). We can make various test cases, and make them work. We are now working on successfully integrating drivetrain into the test cases by setting drivetrain velocities and attempting to shoot at the actual pose of the speaker. The Vision team has been increasing the accuracy of our computer assisted game piece acquisition. This includes training better machine learning models and fixing the distortion of the camera. We have also [...]
