January 9/10

Day two of the season went by in the blink of an eye. Great discussions were made, and our priority list started to finalize. Finishing off day two and starting day three, here’s a recap of what happened.


Our build team worked hard to finish most of the practice field. The Hangar Zone has practically been completed, but some minor adjustments for the Low Rung still need to be made. As we continue to vigorously work, we will hopefully see the whole Hub and Terminal Area finished in the next couple of days. Thanks again to build for getting our practice field done. Now, we can better visualize as we begin prototyping.


               

With our priority list finalized after day two, our team has done much research and looked into shooting in the Lower Hub this season. Having to understand that point values are very valuable this season, we think that there is much value in having a fast cycle time, so targeting the Lower Hub would best meet our needs. In terms of the game and how we want to play it, defense is a must. Building a robust robot that can push away others from scoring, while also being able to take a hit will hopefully keep the opposing alliance from scoring much in this game where each ball is valued greatly due to small points. By taking a route of shooting from the Lower Hub, we aim to get the ranking point during teleop, and prioritize the High Rung during the endgame, we hope to get another RP.





                  

We started to prototype a lot more today. From testing out the intake system to building a shooter prototype, our team worked to find a simple solution score optimally with the game elements. We tested variations of wheels including 2inch Mecanum wheels with an omni wheel in the center, and different strengths of 4inch compliant wheels. From what we have seen, it would be best to consider using 4inch, 35A (durometer) compliant wheels for a start.

 












Once we have these mechanisms tested out and have a direction and sense for how we want to implement these techniques, it will be time to CAD. With finals this week, the Wednesday general meeting will be canceled, but nonetheless, hard work will still be exhibited. For now, good luck!

New and Improved!

Hello and welcome to the new blog for Team 2658: Σ-Motion! If you are new, this is the sanctum where our officers share some of the successes, failures, and lessons learned from ongoing projects and events. The blog originated from Toshko Andreev, a 2658 alumni and ex-president. He gifted us the blog posts for the 2020 and 2021 seasons on another platform (We are switching to blogger for more exciting features!). Now, we would like to share some of the progress on things that we have been working on.  Following our many successes from the 2021 season , the team has been hard at work in preparation for the approaching 2022 season. Due to the unfortunate circumstances during the season this year, the team has jumped to the idea of building our award-winning robot (Whirlpool) this summer/fall to help develop our hands-on skills. Whirlpool Breakdown From the use of our bandsaw and drill press to the use of our mill and CNC router, members of the build team are getting parts done on all l

January 26

As we enter the second week, we have been designing the main structure of this year’s robot. Working over the week and going into the weekend, we’ve made many sketches and calculations along with dimensioning and optimizing the alignment of mechanisms. Starting from the base up, we have the drivetrain. This year we have decided to use a Tank Drive because this fast pace game challenges us to have speed in our driving rather than accuracy. We saw many advantages to a Tank Drive than a Swerve drive in that testing a swerve drive would be very risky for our software team. We have never used a Swerve Drive for our robots before, although arguably useful, the better alternative is the Tank Drive. Additionally, our drivers are already familiar with the controls that accompany it. This simple design allows us to maximize the spacing on a 29.5x29.5 square inch drivetrain and reduces the spacing issue we’ve had in the past between mechanisms and electrical designing.

January 17: Wrap Week 1

What better way to start the first week of the season, than to start with a full week of finals! Even with finals on our schedules, we have worked after school to prototype, design, build, and test potential mechanisms that we may implement this season. As the week progressed, we prototyped, worked on essays, and surfed the internet for new ideas and other feedback. Our build team has completed a vast majority of the practice field. It was great to see the Upper and Lower Hubs completed. On the same day, we finished building a shooter prototype so we were able to extensively test that in terms of compression and angle adjustment. As we prototype, we start to hold multiple design reviews. In these critical design reviews, we essentially have broken down profiles and ideas of the soon-to-be robot. Making sure we follow guidelines from our season-strategy priority list, we take into consideration the benefits and necessary improvements our robot must have this year to compete vigorously i
