January 17th



Hello team,

Finals week just finished and we should be able to ramp up productivity on some missed deadlines (most notably finishing the field elements and working on autonomous). However, this past week was not void of progress.

Design-wise, a considerable amount of progress was made on the elevator. The primary structure is in place but motors, climb attachment, and some extra details still need to be worked out. Some initial block-modeling for the linear actuator for the tube has also begun. Design should be able to meet the Sunday deadline for the finalized second mechanism and have parts ordered soon thereafter.





Pictures of the elevator in different positions. Underneath the tube you can see the initial block-CAD for the linear actuator.

Drivetrain parts were ordered and most were received. Some 2x1 tubing and aluminum sheet metal was sent to our waterjet and milling sponsors for precision work and we should receive that back soon. As soon as Build gets those finished pieces assembly should commence right as planned.

The drivetrain parts we have so far clearly labeled and organized in a tote in the build room.


Although they only met for a brief window earlier this week, build was still able to attach the lowest hardstop for the shield generator. Some adjustment may have to be made but it seems generally good for now. As for what should be done over the weekend (or first thing when we come back to school if we aren't able to secure time to work over the weekend) would be the top hardstop for the shield generator as well as completing the leading bay with it's curved pieces. Once that is complete, build should be right on track and free to work on prototypes until the drivetrain pieces come. Once we start working on the robot we should still hopefully have a small team ironing out details and iterations of sub-assemblies with prototypes.

That's all for now but we should hopefully have more of these updates as we move faster through the robot process.

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

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
