Swerve Drive Specialties 2019/2020, Price Reductions and New Products

Price Reductions

  • We have a new source for our bevel gears. The new gears are still high quality and have been toughly tested.

  • Cost savings have been rolled into the price of the MK2 module kits as well. Lower prices are also great for teams who already purchased MK2 modules as they will be able to put a lower price on their BOM.

    • MK2 fundamentals kit has reduced from $380 to $300
    • MK2 standard kit has reduced from $475 to $400
    • MK2 standard kit with all steel gears has reduced from $485 to $410

Java Template Code Updates

  • The MK2 swerve template code will be configurable for NEOs, Falcon 500s, and brushed motors. Whatever combination of motors on CAN and/or PWM that you wish to use will be supported. These updates will be made public once we receive our falcons and have verified everything is ready to go.

That t-shirt was the fastest purchase I have ever made!

Even though I don’t see my team buying swerve, those price decreases on the bevel gears are really nice. The wheel is also nice but I think the shirt is the real winner!

tfw no shirts in my size… I need to lose weight for more than one reason -____-

Fantastic update to one of the best modules on the market at the moment! Competition is absolutely fantastic, and seeing the other wheel options and lower price point surely makes this even more attractive.

I can’t seem to find CAD files for the bevel gears. Do you have step files, or should I save as the ones in the MK2 swerve module?

Patrick - how have you tested the bevel gears? In a competition yet? And are they the same grade of steel?

What is the new bolt do you recommend? if we go from a Screw 10-32 X 3/8 Cap to 10-32 x 5/8 or 3/4

The pair of motor spacers comes with:

  • Qty 2, 10-32 X 2.75" Socket Head Screws
  • Qty 4, 10-32 X 5/8" Socket Head Screws

These are the longer screws that are recommended when using the spacers with the MK2 module.

CAD files for the bevel gears have been added to the product pages.

The gears are the same type of steel. 2910 used bevel gears from the new supplier at Chezy Champs, Peak Performance, and WA girls gen this fall. They are holding up great.

I think that 1533 and 16 have already proved in 2016 that every game is swerve friendly

It can be made to work, I’m not sure if we’re presented with a game like 2016
a) I would choose to run swerve the first time in competition or
b) that a COTS module is viable, as opposed to a
custom one.

A lot of the big appeal of swerve to me right now, among other things, is that I can buy great COTS modules and not spend build season time or machining resources on making them.

“Every game can be played with a swerve drive” != “Every game is a good enough swerve game to justify the design choice”

What design choice? You can buy COTS modules nowadays.
Programming and budget choices is closer to the mark.

Design choice in the broader sense of “will this part of our robot design help us achieve our goals this season.”

Hate to break it to you, but design is not the same thing as CAD.

No need to be rude.
The swerve game has advanced considerably since I was a student. 2791’s old custom swerves that I loved in high school come from a completely different set of constraints than are present today. Back then, there were still “design” challenges associated with swerve. However, single-line comments saying “design is tough” do not accurately portray the different “design” challenges associated with modern swerves. Programming and budget are examples of more specific barriers than the ephemeral “design” you point to. Feel free to elaborate on what you mean by “design” in this instance.
