Sigma Motion Systems 🇺🇸

@comma_ai 😆

Where have I seen this before?

This is what they mean when they say “locked tf in.” The heel toe action, the glasses, the smirk. Renault F1 V10 dyno bench test.

Back to the track.

How to BEST install your motion system...

Compliments.

Boom! The Sigma 2+ from AK Sim Racing instagram.com/p/DVfBfG8kbva/

Sigma 6+ Motion System with all the goodies.

skrsimracing.com - Lansdale, PA - great place to try a DK2+ system on the east coast!

@_boostedmedia Torque, an easy metric for most people to understand and use for comparison, but its not the whole picture. Just like 0-60 times for cars. ;-) A Tesla might be faster to 60 than a Porsche, but a Porsche is lighter and a better long term performer overall.

VNM has quietly built one of the most interesting Direct Drive lineups in Sim Racing - and it's not just about Torque! boostedmedia.net/sim-racing/har… #simracing

😄 The point being not who 'others' are but how Sigma drives value for the customer. We use premium hardware, skip the expensive marketing, reseller margins and provide a better end product to the customer... Product 'quality' can be subjective, but we measure it in three ways. Mechanical, electrical and software (algorithmic) execution. Mechanical: only company to use billet made actuators, pistons and components for excellent rigidity and haptic feedback. Electrical: using premium American made servos (motors) with 75-volt DC architecture. Optically isolated for no EMI interference. We calculate our speed, acceleration and jerk algorithms at 10kHz in our real-time motion controller. Algorithmic: take a more humble approach, focusing on the data, and avoiding the reliance on canned effects. This also gives us a consistent vehicle feel in each software platform without having to constantly tune each vehicle to subjective unvalidated preferences. Hope that makes sense.

@SigmaIntegrale Who are the others lol

Value means, not just the same product at a lower price, but a better product at a competitive price. Nothing beats the DK2, value for value.

@67Designs @mattdykema 💯

Positive news, but within that list several signals colliding. Frontline labor of the quality and attitude needed in today’s modern manufacturing facility at the SMB level remains very hard to find. The #1 constraint in fact, not capital. The educational gap between the output from high schools and what industry needs is massive. The greatest opportunity today is the creation of a national program to take kids as young as 6th grade into “for the love of your country here is how things get made” hands on training and inspiration programs. We have failed generational knowledge transfer and we must fix that by replacing the keyboard addled fathers and create ‘shop’ and inspire the next generation to appreciate manufacturing and working with their hands and their brains. To encourage every young boy (and girl) to find the joy in making things in atoms and not just consuming the world of bits through a 2D LCD watching Twitch. The greatest risk is not capital constraint, it is having enough urgency in developing jobs and opportunity for a joyful life making what we need for our society and to defend our nation and way of life.

🚨 HOLY SMOKES. Here’s what it means in REAL manufacturing numbers: 2.4% inflation = raw material volatility tightens → contracts stabilize, margins stop getting crushed 1% rate drop on a $2M equipment loan = ~$20K–$25K/year saved +$1,400 real wage growth = retention pressure eases across plants +172K private jobs = industrial demand expansion across supply chains Fuel -10% YoY = freight + distribution costs fall Industrial rent softening = lower fixed overhead per sq ft 100% private job creation = capital flowing into productive sectors If sustained 12–24 months: -Capacity utilization climbs -CapEx orders increase -Hiring stabilizes -Domestic output expands That’s what a real manufacturing boom looks like.

@patinaresearch When F1 was F1. 👏

I wonder what they would think about F1 from 40 years ago

Rod end to Rod End Sigma DK2 Actuator. If yaw know, yaw know.

OEM's have often engineered cars with inherent understeer for "safety"... as most people panic brake and hold the brake until the vehicle is stopped. Some of these new systems/sensors can really push towards a more neutral and controlled loss of traction, that might ultimately be safer.

Polestar 1 snow day! It’s a weird car to slide, but also magical. The combustion engine is only hooked up to the front wheels so the two mechanically unlinked rear motors provide an INSANE amount of instant torque vectoring allowing the car to NEVER understeer. It’s totally wild but need to be careful to not give it too much throttle as the front axle can easily overwhelm the rear as it has much more power up front. I’d love to get this car on winter tires but can’t find a set that fits the factory wheels. Here on summers, the speed is low but it also gives the rear motors a chance to show off that insane torque vectoring capability on low mu. Nice work to the @PolestarCars chassis / powertrain team!

@itskyleconner @LucidMotors Good yaw control. Would be interesting to see what the control systems are actually doing in terms of center power transfer and wheel to wheel torque transfer... The handling dynamics seem like a rally car in disguise 🥸...

Many cars now have 2 motors on the rear axle but almost nobody tunes them properly Lucid spent considerable time on their powertrain torque vectoring and slip targets to make the Sapphire turn into the hand of god Watch as I demonstrate the benefit of Lucid’s logic around front / rear slip targets AND individual motor torque vectoring on the rear axle - curing any hint of understeer and making the car incredibly agile On top of this think about how hard it is to estimate actual vehicle speed when all wheels are spinning all of the time - especially when all of the drivetrain calcs / decisions are made off of % of slip, factoring mu levels, all relative to vehicle actual speed. Pure magic - nothing but respect for the lucid calibrations team 👏🫡 🤯
