Team 2557 Mid-Season Shifting Differential Swerve Release

As we load into our second district event today, team 2557 proudly presents the latest development in our effort to push swerve to its limits: our newly implemented shifting differential swerve drive!

Going into the season, we opted to use our original shifting swerve with the goal of maximum maneuverability while maintaining the ability to both resist defense and play it effectively ourselves. After the fun we had using this capability during our first event, we decided to pull the trigger on this project to fully maximize the defensive ability of our swerve and challenge ourselves in the time between our week one and week five competitions.

The module is driven by a dual Falcon 500 input and shifts via the same ball shifter and rocker arm assembly as our original shifting swerve. The ratios on the shifter are optimized to produce calculated free speeds of 21.66 ft/s in high gear and 6.36 ft/s in low gear. As with the original design, all gears and bearings are available from COTS suppliers and all custom parts should be manufacturable with a lathe and 3-axis CNC.

As a final note, it might be appropriate to comment on our potentially suspicious lack of real photos. This shortcoming is due to the fact that this is, aside from the very real CAD, completely fake. April fools, please don’t ever actually build this monstrosity.

your guys defense at your week one event was nuts cant wait to see you guys at bonney lake

i had to double take as i was actually expecting it to be real due to shifting swerve being a thing and it actually looking about right for the free speeds from the shifting swerve
