Week 5 is a busy one for team Iron Claw as we prepare for our upcoming competition. Our CADers have been working day-in-and-out, finalizing the designs of the intake, shooter, and arm. Last week, we decided to change the intake from over the bumper to under the bumper to provide adequate space for an object detection camera, as well as to make sure the intake is as robust as possible. With the addition of our under-the-bumper intake, we eliminated one degree of freedom from our robot. Additionally, we began assembling our prototype, and tested intaking as well as centering as it goes into the shooter. With the new intake, we tested out two centering mechanisms. The first was a set of polycarbonate plates that were bent to create ramps between the rollers. In our testing, we tried several types of surfaces including smooth polycarbonate, sanded polycarbonate, velcro loop, and masking tape. While sanded polycarbonate showed potential, we decided that none of the materials were successful enough as the note jammed on the side. Due to the failure of the plates, we decided to experiment with a pair of passive wheels that would direct the game piece toward our shooter. This seemed to work better, but we are transitioning to a powered wheel solution for the final design, using [...]

Week three concluded with a DVC (Decision Voting Council) vote on our subsystems. As a team, we extended our prototyping process to ensure that our DVC could use the data and information collected to make an informed decision. We also created an integration team that is responsible for researching possible ways to package and integrate the subsystems onto our 26.5” x 26.5” swerve drivetrain. Below is an overview of how the final prototypes progressed and finished over the week. This year, when presenting the final subsystems, the prototyping teams ensured they validated the capabilities against the functional requirements that the team created in week one. The Fliptake team finished a CAD of the prototype and simulated the full range of motion. We also worked on mounting it to Phil, our off-season swerve robot, to test its ability to intake while driving. In its stowed position, the two rollers of the Fliptake are positioned halfway across the robot with a polycord infinity loop, allowing spin in opposite directions. Incorporating a self-centering board cements the note to flip back on the pivot and handoff to the shooter. However, we found that the self-centering board acted as more of a hardstop for the note. During data collection, we accomplished a 100% success rate during 25 trials from the center using the stationary [...]

After last week’s success, we have progressed further on our prototypes, succeeding on many fronts. As a recap for week 1, our DVC (Decision Voting Council), decided on a series of mechanisms that we would prototype and test the geometry for before we decide on our full robot design. Those prototypes are:  Fliptake: an intake consisting of two rollers on a pivot, allowing it to flip and outtake a note into another subsystem. Continuous Intake: an intake that brings the note over the bumper into an indexer. 95-Style Shooter: a shooter design where the shooter wheels are vertical and coaxial on 2 axles that vertically compress the note to fire it. Elevator: a one or two-stage climbing mechanism that may also place a note in the trap on the final robot. Flywheel Shooter: a shooter that has two shooter wheels that are horizontally mounted which compress and fire a note. Big Arm: a climbing mechanism that has an arm that winches down onto the chain to climb up. The prototyping groups are making great progress, they are now focused on collecting data to validate their designs against the functional requirements of the robot. For our intakes, the Fliptake and the Continuous Intake, we have discussed many options and ultimately decided to put each through second and third rounds [...]

After our most successful season yet, Iron Claw Robotics is feeling upbeat and ready for the 2024 Crescendo Build Season! On Saturday, January 6th, our team met over winter break for our annual kickoff day to watch the game release. This year’s 2024 game consists of a ring-shaped game piece called a note, which can be deposited into three field elements: the amp, speaker, and trap. Although the endgame is not a time constrained section, robots can choose to climb on a chain with other robots or score in traps. Over the weekend, the team focused on strategy, dividing into five groups to discuss the best ways to maximize points and create potential auto paths during matches. On Sunday, after the groups presented their strategies to the class followed by a team discussion, the DVC (Decision Voting Council) voted on our robot functional requirements. These requirements dictate our strategy and what the robot will or will not do, playing a crucial role in our design using specific metrics to follow. Devising a detailed plan for strategy is our first important step to ensure our robot’s success. Throughout the week, we spent several meetings split into five groups to research various designs that uphold our functional requirements and team goals. After designs were presented, the DVC filtered twenty six [...]

Team Iron Claw 972 is already one step ahead of the Crescendo game: our practice field is almost complete and ready to go. Thanks to the hard work from mentors Art Chan and Harrison Van Der Walt, having a practice field will not only be important for driver practice, but also for analyzing the accuracy of prototypes and designs when interacting with the field elements. Additionally, our mentor, Aaron Payne, has provided us with a large space in the wood shop to hold the practice field.             We had four out of the five practice field elements made just within the first 10 hours of Crescendo being published, including the speaker and subwoofer, the amp, and the source.  We are also planning to build the stage field element before the end of build season, but are currently waiting on the trap to arrive from Andymark on January 15th, as well as a vendor to sell us Trusses. All other parts of the stage are planned to be cut out using a CNC router, making the process of assembling the field elements a lot faster than the objects that were cut by hand. We look forward to observing how the creation of our field this early in the season will influence how we design [...]

Team Iron Claw 972 has had a successful fall season in preparation of the 2024 season, but with several new changes. Our team elected a competition council of 11 members, who led the fall season adopting a task-based approach. Instead of starting the year with a weekend workshop for newer students, the team leadership was able to introduce students to their technical and nontechnical subteams within class meetings, allowing our team to have more time to focus on efficient training.  Currently our fall season training is focusing around a few advanced projects. Those projects are a Turret, Vision programming, Data Analytics for Robot performance, Data Analytics for Match Strategy, and a standard Swerve Drive Chassis based on a 26.5 by 26.5 frame perimeter with a revised and optimized code base for the SDS MK4i swerve modules. Our team has never designed and integrated a turret onto a competition robot. A turret is a spinning disk and set of gears that allow something such as a shooter to spin a predetermined set of degrees or radians. The turret project allowed the team to spend quality time researching various turret designs from top teams across the FRC community, while teaching the new CADers how to create useful designs for the manufacturing and assembly teams. The team finalized a design and [...]

The end of the 2023 season marks a new era of outstanding potential for team Iron Claw Robotics. Throughout the season, each competition we competed in has helped us pinpoint the strengths and weaknesses of our robot, allowing us to improve our robot more and more in preparation for the World Championships. Our hard work paid off as our team celebrated our victory in the Archimedes Division, setting the bar at unprecedented heights. Our first competition, Hueneme Port Regional, was a great way for our team to test our robot early on in the season and enabled us to learn from the innovative designs of other teams. We were able to test and improve our autonomous routines, as well as score a cone in the high node by extending the elevator and the 4-bar arm. One of our most memorable matches in this competition was Quals 75, when our team got a world record score with team 1678, Citrus Circuits, and team 498, The Cobra Commanders. On the second day of competition, we made it to the playoffs, ending in 5th place, and picked team 687, the Nerd Herds, and team 2429, La Cañada Engineering Club, to be in our alliance. Although we lost in match 7 of the playoffs, we learned how we could improve the design [...]

This past week, on Friday and Saturday, our team competed in the Silicon Valley Regional in San Jose. We were able to load in one day early and due to this, we were able to completely dedicate the practice day to playing as many practice matches as we could. During our practice matches we tested out new autonomous routines that were developed and evaluated the limits of the robot.  Silicon Valley Regional was a great competition for our team to demonstrate the new changes made to our robot. At the San Francisco Regional, we would usually deposit a single game piece onto the grid and balance on the charge station during autonomous. However, we tested out the new autonomous routines, which consisted of both two-piece and three-piece routines at this competition. The three-piece routine was able to run when the robot started in a certain position. We were able to score game pieces quicker and more accurately, and we had the same game piece configuration as we did in the San Francisco Regional. Ultimately, our team ended up in 9th place after the qualification matches. During alliance selections, the captain of alliance #3, team 604, Quixilver, invited us along with team 5171, Deus Ex Machina, to join their alliance. Our alliance fought hard against opposing teams, eventually making [...]

As we are approaching Silicon Valley Regional and the Houston Championships, the team has been working hard to prepare for the competition, and we are¥ continuing to make some small revisions on our robot.  Operations plays a vital role in our ability to attend Houston. This past week, the team has continued to write emails reaching out to parents, friends, and other relatives for funds. We have also contacted local and big businesses, seeking corporate matchings for grants. So far, we have been able to raise around 60% of the fundraising goal of $45,000, and we are working hard to reach the full amount needed to fund the competition. Please help us reach our goal by donating on our website! Any help is greatly appreciated, and would help our team attend Houston.  The Mechanical team is finishing creating spares for the robot, including a spare wrist, elevator and intake. Additionally, we shifted to a new bumper mounting solution and moved the bumpers higher to make engaging in auto more reliable.  The Programming team wrote code for a two piece autonomous and engage, and are working up the speeds for a three piece auto in the final days leading up to the Silicon Valley Regional. The team is also working on programming multiple autonomous routines to increase our flexibility and [...]

This past weekend, our team competed in the San Francisco Regional. Placing the robot on the field at the beginning of a match After setting up the pit and making minor mechanical adjustments to the robot, we focused on cycling practice matches to get as much driver practice as possible. During our practice matches we focused on playing with top teams such as 581, the Blazing Bulldogs, 971, Spartan Robotics, and 649, MSET Fish to gauge our robot and driver’s synergy with other teams. Walkthrough of electrical board during inspection With our new roller intake/outtake and wrist, which we designed once we returned from the Hueneme Port Regional in week 1, we greatly improved our performance. Our new roller intake/outtake allowed for quick alignment and acquisition from the single substation, dramatically decreasing our cycle times, driving up our point scoring during TeleOP. Additionally, we worked on refining our Auto routines to allow for improved charge station engaging. Our robot scored well with fast cycle times from the single substation, and we were able to get our autonomous routine, consisting of one cone being placed onto the top node and then engaging on the charge station, working consistently. We ended the day on an optimistic note and were ready for the qualification matches on Saturday. Systems check and elevator [...]
